Knowing that someone would've dumped their unwanted aquarium fish really annoys me as a fish keeper myself. If you want to keep fish, be responsible about it. If you're not prepared to care for these types of fish for the term of their life, don't buy them. And doing some proper research into the fish you're thinking of buying before buying it would be a great idea too. Thanks for bringing awareness to invasive species.
I would hope someone didn’t do this on purpose we have had many large floods in the area in the last couple of years and can only think maybe there pond/tank got taken out
Needs to be better education, most people don't realise local fish stores will take the fish from you. New owners also get told bad information & are destined to fail resulting in them quitting after 2 months & dumping In local waterways
Thank you for bringing this to everyone’s attention, with all the normal life issues like the rent crisis and cost of living we really forgot our backyard friends. I hope some day we can get them out and have our amazing fish selection thriving again. ❤
I'm an old aquatist . These fish have got to be netted out of this system, pronto ! Great that there's a video out there, but we need to get in there and net the bloody things out !!! AND the place needs continued monitoring. Come on Australia !!!!!!
I don’t know if extermination is possible. An example of this is Florida which has dozens of invasive fish species from their aquarium trade. I haven’t heard of them controlling and exterminating even one of the invasive species successfully. The problem is that you literally have to catch every fish. If even a half dozen are not caught - they can breed thousands in the next year or two and you are back at square one. Florida also has ridiculous numbers of nutria (a form of giant rodent) which grows to half a metre. They also have thousands of invasive reticulated pythons and Burmese pythons that grow up to 23 feet. Its a real ark of invasive species, over 500 at last count.
I think the ship has sailed on these but hopefully we can stop others from getting in, they are in every nook and cranny of this system and others, the best we can do is maybe keep them down a little and stop the spread to other waterways that don't have them, this is the main reason for this video.
@@australianbiotopes4563 Yes - education is key here. But unfortunately it just takes one idiot to do the wrong thing. If you can have idiots lighting fires in the middle of a 42 degree day, you will have idiots releasing fish into the system just to be contrary. If the waterway in this video weren’t so huge (like it was a small dam of 5 hectares) you could just bite the bullet and poison the waterway - make sure the Geophagus doesn’t escape the system. But this lake looks gigantic. The fear is this fish might get into other waterways during a mega flooding event. Same way those dozen bull sharks ended ip in that golf course when half of QLD was flooded.
@@Whaleydavey The unfortunate part is the Brisbane River Cod is extinct from over fishing, but the good news is they are now releasing the Mary River Cod that is very similar to the Brisbane River system in large number, so this might bring a large predator back to combat these fish, something that has been lacking for years, we will see in a few years if it helps.
@@australianbiotopes4563 Is that an ideal solution? I watched a RUclips video of how they introduced the Nile Perch into Lake Victoria on purpose. The lake had hundreds of different species of cichlids and most of them were threatened by the huge appetite of this giant fish. However if the Mary River Cod is of a similar size and similar behaviour as the cod it is replacing, I guess there shouldn’t be too much harm done.

I’m a Gold prospector and I’ve learned a lot about many invasive animals through the hobby. There’re so many thorny bushes here that are non native all through the gold fields. Diggers brought the blackberries and thorny trees to provide bush tucker, provide more habitat for non-native animals they brought here that they intended to hunt for food. And brought fish like European Carp, multiple Trout species, Redfin, multiple Perch species I’m probably missing some fish but all these non-native fish compete for resources with native animals not adapted for such competition, and they in turn become threatened by predation and competition for food. Reducing the populations of animals that have lived here and evolved on this land for literally unimaginable amounts of time. Whenever I’m out there it’s impossible to not see an invasive species of something. I always wonder if the old diggers knew that the thorn trees would just take over the fields and make a lot of the gold pretty inaccessible unless you’re wearing a damn EOD suit. I always feel like they’re laughing at me from their graves when I fall into an invasive thorn bush or something. Like they wanted future gold diggers to struggle.

Good job for spreading awareness I live in Perth Western Australia and almost every lake in parks has pearls in them I even drove 3 hours away and still saw them
Thank you! yes pretty upsetting news, once they are there I think they are there for good, I just hope they don't spread into other waterways over there, there are some pretty venerable fish in your neck of the woods.
I appreciate your effort to make this more known in the hobby and public via youtube! Such a shame to destroy old ecosystems by irresponsibly releasing foreign fish.
I’ve seen this kind of thing all over the place. They are beautiful fish, but it’s such a shame that they have ruined the place you like to frequently visit. I will say that the photography is awesome, and you quite eloquently told a very informational story! Great job!
Awesome video! It's really sad to see things like this happening all over the world. I quite often watch videos from Florida and that's just mind blowing how man invasive species they have down there. There are a lot of people that actually think invasive species aren't a problem which is even more insane.
Thank you! yes they are at a whole new level, I don't think there is any turning back from all the invasive species they have, that actually makes me worried we are heading down the same path.
@@australianbiotopes4563 I'm worried about the same thing. I constantly get asked about Vampire Crabs in Australia. They are a banned species from what I am aware but sooner or later some idiot will sneak them in (if they haven't already) and we'll have a new invasive species disaster on our hands. They breed fast and are escape masters so even if people don't intentionally let them out they are good at escaping... We both know how that ends. I wish people were more responsible. At least hear in Europe super cold winters kill most things.
So frustrating to see these Pearl Cichlids in our waterways. Just last weekend I visited Northbrook creek and pulled up over 150 of these in traps (all exterminated). So unfortunate to see their large populations taking over beautiful native Australian fish.
Great video. This might be a dumb question but how do they survive our winter temperatures? I thought they were a warm water species or do they just adapt.
This is so sad! People are irresponsible when it comes to get rid of their pets. Our species is very good in destroying the planet. We live 20 min away from Wivenhoe Dam but I didn't know about this huge problem. Thanks for the video, Jason.
Yes very sad indeed! it's not your fault not knowing, most don't know what goes on even in our local waterways, my aim is to change that as much as I can, mostly it is out of sight and out of mind to most but it's just as important as say our Koala habitat as everything has a chain reaction effect.
@@australianbiotopes4563 we need more people like you. People who don't close their eyes and take action. So much damage has been done by introducing species from other countries. Just look at the cane toads, foxes, rabbits... The list is endless. I feel sorry for those animals too because it wasn't their fault that they ended up in Australia.
Hi Davey, sorry for the late reply. Thank you for taking the time to respond. Much appreciate you commenting. Yes you’re quite right about the isolation aspect of populations. It only takes a furtive female to escape and it’s Florida all over again with rampant invasive species . In Florida, their tropical fish industry is huge. Imports into the States are massive. I have known of Australian Navy personnel buying their marine fish stock from Florida. I suppose my grave concern centres around our fragile waterways and our struggling natives which end up largely as being prey to the invaders due to the nature of the invasive species. And the fact that the invaders spawn so readily here and how the frey are protected . Coming from a scientific background, I just wish that the issue of invasion here, was pushed up the priority list. We are very likely to see total destruction of our natural tropical fish fresh water system to invasive species within a decade. 😢
I lived on Wivenhoe dam 2022 to 2023 and caught cyclids in the dam. I have been 400km West of the coast in FNQ and found cyclids taking over from Sooty Grunter. I have a pet blue gorahmmi I caught in the burdekin.
Yeah it's shocking where you can find feral fish up that way and sometimes makes you wonder how they got there, unfortunately the warmer weather and floods makes for a perfect place for them to spread much easier, people in the tropics have to much more careful or those beautiful places will be ruined, I've come across some scary stuff while filming, it makes me angry some times, hopefully it doesn't get out of hand.
@@australianbiotopes4563 we also have a pet Red Devil about 30cm long caught in Ross River Townsville. We use talapia as Batr bait and join forces to eradicate the pests. The talapia in salt water are good eating I hear 😋👍
@@patrickmcmanus5373 Yeah we got them down here to in the local man made lakes and they have reverted back to their wild colours, nice fish but they don't belong. Just be careful using the Tilapia, if you get caught with it in your possession dead or alive there are big fines, Stupid law as you can buy the flesh now in seafood shops but it's imported of course so the money goes back overseas rather then fixing a problem here. Tilapia actually has a really nice flesh and is farmed all over the world and if you ever have imported fish fingers you are probably already eating it, this country needs to get with the times and maybe try and fix a problem at the same time make some money in the process, we are never going to be rid of them now, they are in just about every waterway this side of the Great Dividing Range and in WA. they should just let people catch and keep if they want to, dead of coarse for food, most will even release them back because they are a no keep fish, I've even spoken to Bio Security about it and it's like talking to a brick wall they are set in their ways with no good outcome.
Great video and footage. Such a horrible shame, impossible to eradicate now no doubt, man a few really stuff it up for the rest of us don't they, so frustrating.
Yes! they don't realise this fish could one day be deemed as noxious and then no one will be able to keep it, not to mention it will make it tougher to keep other fish as well.
Just came back from camping in Imbil State Forest near Kenilworth, caught one of those and a few green swordtail that are also super invasive apparently. 😢 I didnt have internet connection to check if it was invasive, now that i know, next time im there i will net them all.
Ive seen these fish in a remote water hole up in the mountains ( D'aguilar Range) which feeds down the range into Wivenhoe. How do they get into a waterhole like that, when the only water that feeds it is trickles through the rocks?
What part of the river are you at I live near the Wivenhoe dam and surrounding rivers I will pass the message on to all the fisherman I know of around this area
They are still patchy but they are slowly spreading unfortunately, they don't readily take bait like most fish being that they are sand sifters, still they do occasionally get caught.
At 4.14 when the river starts to be noticeable of damage that's when you chuck in big starving catfish from fish farms tried it in carp worked sorta just to many carp but it brought the numbers down abit
They are actually releasing a whole heap of Mary River Cod into the catchment to replace the closely related now extinct Brisbane River Cod, so hopefully when they grow they will cut down the numbers of them and Tilapia, it will be good food for them anyway.
What a shame we've got another pest putting pressure on our waterways. Lovely clear water though! Which creek is this? Is it deep enough for snorkelling?
I think Australian Environmental Departments and Fisheries have to step up and start banning the sale of harmful non-endemic species to save our own wildlife, repair damaged habitat. The list of noxious fish and plant species is just growing bigger, from Gambusia to Tilapia and on and on. You can't sell Queensland as a pristine natural wilderness anymore; that is a joke.
2 Questions. Are they the only fish in QLD waterways with the metallic pattern on the face, so it cannot be mistaken for a native? Are they any good to eat?
Yes it's bad for invasive up there unfortunately, the warm tropical climate doesn't help, at least down this way a lot dies off through winter, but a few tough survive.
No reason why not, just like any other freshwater fish, probably taste nice smoked, and can be collected as they are only invasive unlike Tilapia that are noxious, the only problem is they are a bit fussy with what they eat as adults being sand sifters, I dropped a pile of live worms in front of them while snorkelling and they ignored them and kept sifting, you may get the odd one, the young readily take the bait though and grow fast, so maybe good for aquaculture.
I catch them all the way up the headwaters of the creeks n rivers feeding the Brisbane River.. and in billabongs all thru the forestry..they everywhere :(
It was bad enough when we were dealing with carp and tilapia. Lately (the last 5-6 years) I've been hearing more and more reports of these fish around the western areas of Brisbane. Then plecostomus. Then oscars. I even read reports of peacock bass found near Mackay. Rumors of wolf and jaguar cichlids and red devils are also getting about. We're starting to look a lot more like Florida every day it seems.
I've actually seen the Red Devils in Forest Lake, but you can't fish there, someone showed me a pic of Texans down the Gold Coast, it's really sad, this type of thing will toughen the laws on keeping if people aren't careful, it's getting that way a bit, if we aren't careful we got the perfect temps. here we will be the Florida of Australia.
@@TheCaptainbeefylog Yes I agree, it's peoples fault though, I used to fish my local lake and they would show a blind eye to it, then people started leaving their unwanted line with hooks and sinkers and unwanted bait behind, they also would lite fires along the bank at night to keep warm, and basically just ruined it for everyone, people started complaining and now they have cracked down on it, once this type of thing happens it's hard to reverse the damage done, now the fish will keep breeding unchecked and overflow into our waterways, I think the local councils need to get onto this if people can't fish for them, it's their responsibility to eradicate them, or it's basically just a breeding program for a noxious species.
Yes it would but unfortunately if we have one cold snap in these impoundments they all die as it can get to cold for them, good news is they are releasing a heap of Mary River Cod into the system, but it will take a few years for them to grow.
Tilapia have become a problem in just about every creek from the sub tropics of NSW to Far North QLD along the coastal waterways inland to the Great Dividing Range, this is why I posted this, it could happen with these as well if we're not careful, it's bad enough having one, we don't want another.
If they were below the dam, i would've thought that they could've gotten out of tanks in houses when they went under during the floods. It's sad to know that people have deliberately released them, as they cant get up that side of the dam wall, unless it was from houses that went under in the upper catchment areas.
Not to mention they have been there longer than from the last few floods, the only difference I've noticed is that they seem to breeding much more rapidly now, or maybe there is just a whole lot more that they are being noticed more.
Invasive species are terrible & perhaps impossible to stop (eg. Carp) once introduced. Fish keepers and owners of foreign species perhaps, need licencing. This may pay for education. I'm happy for such, if introduced, as it would be a step forward to stopping such blights
I removed one from Wivanhoe dam about 6 months ago and have since caught fry(babies) at another dam while visually seeing a breeding pair that I was un able to catch although if I had a cast net that could have been a different story
If I would of been able to use a spear or spear gun I could of got a whole heap of them but just like cast nets they are illegal to use in freshwater creeks that aren't tidal.
@@australianbiotopes4563 I haven't looked into cast net laws I'm from NSW but staying in Qld for awhile so learn something new everyday but yeah next time I'm at this dam they'll be my target species
@@GU-24-WD You can in tidal brackish though, that was like last time I went down to NSW and found out you can't use them down there, they should really change the laws nation wide, it would make things easier.
I've been trying, I get everything else but them, they don't seem to want to go into traps, you get the occasional one, the young are easy to catch on hooks but the adults are more fussy, as earth eaters, I even threw live worms in front of them while snorkelling and they ignored them and just kept chewing the bottom.
@@ladypeiandtheclown5410 It's illegal to spear fish in freshwater or I would of done that, while I was snorkelling you could see how close I could get to them, they weren't afraid.
What we need is a native predator to be introduced to this dam because as we aquarists know big fish eat little fish . There will be obvious decimation to other species but these can easily be re-stocked .
We used to have one, the Brisbane River Cod, but is now extinct , the goo news is they are now re-stocking the Mary River Cod back into the system, they have just not long released thousands of fingerlings, they are really closely related to our extinct cod and I think in a few years when they start to get size to them it will help.
It may not just be people being irresponsible, it could also be lack of education, some people don't know any better and don't want to harm the fish and think by setting them free is an option, that is one of the reason for these videos to educate, yes there are probably irresponsible people as well, our local fish club has done up a heap of posters to educate people as well and we have as a group started to hand them out to fish stores to try and help this problem, hopefully it will stop it as much as it can, Most good stores will take unwanted fish back as well as an option to be re-homed.
We will have to wait and see how they go up agains the thousands of Mary River Cod that have been released into the system to replace the now extinct Brisbane River Cod, maybe it will restore the balance, we can only hope 🙂
Yeah it's annoying but better out then in, next time I go out and catch some big ones I'm going to see how they taste, maybe smoke them, the good thing is you can take them home where you can't with the Tilapia.
I just don’t understand why there are not greater restrictions on species the aquarium trade can sell, and why criminalising the release of non native species cannot be reinforced at point of sale. Mum and dad getting little Johnny a fishtank for his room may not have any idea they are doing the wrong thing in liberating the family pet once its outgrown its tank. Educate these people at point of sale and warn of the severe consequences, environmentally as well as legally.
Similar but the Green Terror is from the western side of South America, they are both in the family cichlidae but different sub family, apparently they are around in small numbers to in other areas.
It's been warm for an extended periot, eventually a nasty winter will knock em out I imagine. Still, idiots dumping Cichlids and taking out the native stuff in the mean time.
These have been here for probably over 20 years and are cold tolerant, they come from South America but the areas they come from pretty much match our climate in SEQ. they probably won't get down further south but if they get into some of the waterways further north there could be more problems, they have just become more prolific in the past few years so they are seen a lot more.
Sadly, there will always be people who just don't GAF about the impact of their actions on the Australian enviroment no matter how much information/education is out there. Is the infestation of pearl cichlids so large it cannot be eliminated?
Pretty much, they are right through the system now, and have been found elsewhere as well, with the amount of young they have and how successful they are, I think we are stuck with them.
It is sad that people have been advised to limit the fish, they are so beautiful. The activity of the fish and how they protect their young is awesome. It ends with good news, nice to hear that you protect them too.
I don't protect them they are a feral species and do a lot of damage, there is no good outcome, they are destroying the local ecosystem and there is no way now to stop them.
In their natural environment they aren't a problem because they have natural predators, but here were they don't belong they are doing a lot of damage unfortunately, they have damaged this creek.
@@Manumanunitomidri I agree it's not the fishes fault, but that doesn't change the fact of the damage they do, this is why I am making people aware so they know what damage can be done and maybe stop it happening in the future.
Unfortunately it's illegal to spear fish in freshwater creeks and it's not worth getting fines for it, a bit of a joke, they won't even bend the rules for invasive fish or I would of had the place cleaned out.
Knowing that someone would've dumped their unwanted aquarium fish really annoys me as a fish keeper myself. If you want to keep fish, be responsible about it.
If you're not prepared to care for these types of fish for the term of their life, don't buy them. And doing some proper research into the fish you're thinking of buying before buying it would be a great idea too.

I have tried to share it where ever I can, I also have some friends here that work or have worked in that field that are sharing it as well, lets hope the word gets around, I am going to try and make more of these on other invasive species as I collect the footage as well to make more people aware of this, I'm also in local fish clubs and they have shared them as well, feel free to share it around as much as you can, Thanks 🙂
just quickly wanna thank you for the quality videos you post jeep it up!
Thank you! I try and better my self each time I learn a little more.
Thanks for sharing and raising awareness.
It's an important subject, Thanks for watching and feel free to share it around 🙂
Good job for spreading awareness I live in Perth Western Australia and almost every lake in parks has pearls in them I even drove 3 hours away and still saw them
Thank you! yes pretty upsetting news, once they are there I think they are there for good, I just hope they don't spread into other waterways over there, there are some pretty venerable fish in your neck of the woods.
@@australianbiotopes4563Pearl cichlids can even live in salt water
@@kangaroo0177 Yeah I've mentioned that in other comments, they are very tough.
Caught one a year ago in Bassendean...
@@peteh7966 Sad to see they are over there as well.
I appreciate your effort to make this more known in the hobby and public via youtube!
Such a shame to destroy old ecosystems by irresponsibly releasing foreign fish.
Great message mate! People need to be more responsible!!!
Thank you! yes they do, some probably don't even realise, so I hope to spread the word.
Great video Jason 👍🏽
Thank you! and Thanks for watching 🙂
I’ve seen this kind of thing all over the place. They are beautiful fish, but it’s such a shame that they have ruined the place you like to frequently visit. I will say that the photography is awesome, and you quite eloquently told a very informational story! Great job!
Thank you! and thanks for watching.
Another excellent video pin pointing what an invasive fish can do. Thanks
Thank you! and thanks for watching 🙂
great video dude keep it up 👍
Thank you! 🙂
Awesome video! It's really sad to see things like this happening all over the world.
I quite often watch videos from Florida and that's just mind blowing how man invasive species they have down there.
There are a lot of people that actually think invasive species aren't a problem which is even more insane.
Thank you! yes they are at a whole new level, I don't think there is any turning back from all the invasive species they have, that actually makes me worried we are heading down the same path.
@@australianbiotopes4563 I'm worried about the same thing. I constantly get asked about Vampire Crabs in Australia. They are a banned species from what I am aware but sooner or later some idiot will sneak them in (if they haven't already) and we'll have a new invasive species disaster on our hands. They breed fast and are escape masters so even if people don't intentionally let them out they are good at escaping... We both know how that ends.
I wish people were more responsible. At least hear in Europe super cold winters kill most things.
Chuck Palahniuk . . the sinister author of Fight Club , 'fiction' book . . recounted in the book Haunted . . the invasive species US
@@benwinter2420 Well even parasites have a limit we don't unfortunately.
Can go into rabbit control 'programs' in Australia in past . . but it seems a sore topic
I've recently seen them in the Liege Street wetland and the Cygnia Waters wetland along the north shore of the Canning River.
That's no good Thanks for letting us know.
Well made! Great video
Thanks mate! 🙂
So frustrating to see these Pearl Cichlids in our waterways. Just last weekend I visited Northbrook creek and pulled up over 150 of these in traps (all exterminated). So unfortunate to see their large populations taking over beautiful native Australian fish.
Nice one! I'm happy to hear you got out so many.
Great video.
This might be a dumb question but how do they survive our winter temperatures? I thought they were a warm water species or do they just adapt.
Southern South America probably gets colder then here, we are used to seeing all the jungles but we aren't much different.
This is so sad! People are irresponsible when it comes to get rid of their pets. Our species is very good in destroying the planet.
We live 20 min away from Wivenhoe Dam but I didn't know about this huge problem.
Thanks for the video, Jason.
Yes very sad indeed! it's not your fault not knowing, most don't know what goes on even in our local waterways, my aim is to change that as much as I can, mostly it is out of sight and out of mind to most but it's just as important as say our Koala habitat as everything has a chain reaction effect.
@@australianbiotopes4563 we need more people like you. People who don't close their eyes and take action.
So much damage has been done by introducing species from other countries. Just look at the cane toads, foxes, rabbits... The list is endless. I feel sorry for those animals too because it wasn't their fault that they ended up in Australia.
@@Bonnie10au Exactly! Thank you, I just want our kids to enjoy what I have.
Mozambique tilapia (Oreochromis mossambicus) have taken over the lower Chapman River system here in Geraldton.
Yes they are like Cane Toads now, almost in every creek on the east coast where it is warm enough for them.
Hi Davey, sorry for the late reply. Thank you for taking the time to respond. Much appreciate you commenting. Yes you’re quite right about the isolation aspect of populations. It only takes a furtive female to escape and it’s Florida all over again with rampant invasive species .
In Florida, their tropical fish industry is huge. Imports into the States are massive.
I have known of Australian Navy
personnel buying their marine fish stock from Florida.
I suppose my grave concern centres around our fragile waterways and our struggling natives which end up largely as being prey to the invaders due to the nature of the invasive species. And the fact that the invaders spawn so readily here and how the frey are protected .
Coming from a scientific background, I just wish that the issue of invasion here, was pushed up the priority list. We are very likely to see total destruction of our natural tropical fish fresh water system to invasive species within a decade. 😢
Thank you for commenting but who is Davey, I know my name isn't and I'm the only person doing this channel 🙂
I lived on Wivenhoe dam 2022 to 2023 and caught cyclids in the dam. I have been 400km West of the coast in FNQ and found cyclids taking over from Sooty Grunter. I have a pet blue gorahmmi I caught in the burdekin.
Yeah it's shocking where you can find feral fish up that way and sometimes makes you wonder how they got there, unfortunately the warmer weather and floods makes for a perfect place for them to spread much easier, people in the tropics have to much more careful or those beautiful places will be ruined, I've come across some scary stuff while filming, it makes me angry some times, hopefully it doesn't get out of hand.
@@australianbiotopes4563 we also have a pet Red Devil about 30cm long caught in Ross River Townsville. We use talapia as Batr bait and join forces to eradicate the pests. The talapia in salt water are good eating I hear 😋👍
@@patrickmcmanus5373 Yeah we got them down here to in the local man made lakes and they have reverted back to their wild colours, nice fish but they don't belong. Just be careful using the Tilapia, if you get caught with it in your possession dead or alive there are big fines, Stupid law as you can buy the flesh now in seafood shops but it's imported of course so the money goes back overseas rather then fixing a problem here. Tilapia actually has a really nice flesh and is farmed all over the world and if you ever have imported fish fingers you are probably already eating it, this country needs to get with the times and maybe try and fix a problem at the same time make some money in the process, we are never going to be rid of them now, they are in just about every waterway this side of the Great Dividing Range and in WA. they should just let people catch and keep if they want to, dead of coarse for food, most will even release them back because they are a no keep fish, I've even spoken to Bio Security about it and it's like talking to a brick wall they are set in their ways with no good outcome.
@@australianbiotopes4563 a scientist told me that they have been catching feral fish since 1960
Great video and footage. Such a horrible shame, impossible to eradicate now no doubt, man a few really stuff it up for the rest of us don't they, so frustrating.
Yes! they don't realise this fish could one day be deemed as noxious and then no one will be able to keep it, not to mention it will make it tougher to keep other fish as well.
great video
Thanks!
Keep reporting great work
Thank you! I definitely will 🙂
Just came back from camping in Imbil State Forest near Kenilworth, caught one of those and a few green swordtail that are also super invasive apparently. 😢
I didnt have internet connection to check if it was invasive, now that i know, next time im there i will net them all.
Ive seen these fish in a remote water hole up in the mountains ( D'aguilar Range) which feeds down the range into Wivenhoe. How do they get into a waterhole like that, when the only water that feeds it is trickles through the rocks?
What part of the river are you at I live near the Wivenhoe dam and surrounding rivers I will pass the message on to all the fisherman I know of around this area
I’ve never known this fish was even in our waterways. This is crazy that they’re in reservoirs and waterways. I’ve never come across them.
They are still patchy but they are slowly spreading unfortunately, they don't readily take bait like most fish being that they are sand sifters, still they do occasionally get caught.
Cichlid is a good fish to eat, may be we should drop a few lines down and get ourselves a free dinner
Yes they are healthy in that pristine water to.
Thank you for your dedicated work. This country has way too many imports, in the water and in the streets.
Thanks for watching! 🙂
1:52 is that a tetra ? Which creek is it ?
No it's an Australian Smelt.
As if the Tilapia, livebearers and carp weren't bad enough
Exactly! mate it is upsetting to see.
@@mseeker369 Yes we will never be rid of them, I have seen them in just about every creek up the east coast of QLD.
@@mseeker369 Yes they have been in there for awhile, hopefully the Mary River Cod they are now releasing will cut them down a bit.
At 4.14 when the river starts to be noticeable of damage that's when you chuck in big starving catfish from fish farms tried it in carp worked sorta just to many carp but it brought the numbers down abit
They are actually releasing a whole heap of Mary River Cod into the catchment to replace the closely related now extinct Brisbane River Cod, so hopefully when they grow they will cut down the numbers of them and Tilapia, it will be good food for them anyway.
Music is a bit loud at some points bro. Solid info though, cheers
Thanks for your feedback, yes I noticed my self once it was published, I fixed it in the next one.
@@australianbiotopes4563 Keep up the good work. Very informative
What a shame we've got another pest putting pressure on our waterways. Lovely clear water though! Which creek is this? Is it deep enough for snorkelling?
Yes nice place to snorkel, it's the lower reaches of Northbrook Creek.
I think Australian Environmental Departments and Fisheries have to step up and start banning the sale of harmful non-endemic species to save our own wildlife, repair damaged habitat. The list of noxious fish and plant species is just growing bigger, from Gambusia to Tilapia and on and on. You can't sell Queensland as a pristine natural wilderness anymore; that is a joke.
They are every where in Perth area
2 Questions.
Are they the only fish in QLD waterways with the metallic pattern on the face, so it cannot be mistaken for a native?
Are they any good to eat?
Yes, there are a few saltwater species but they are the only freshwater ones.
@@australianbiotopes4563 Thanks, any good to eat? I'm in Yeppoon. Any sighting of them in the Rocky region?
@@geoffbreen2386 Depends if you like freshwater fish I guess, no they are pretty localised to here for now.
Cichlid are insane. I had one small convict take on two large Oscars. It had to be moved to a different aquarium.
Yes they can be really aggressive.
What is wrong with people to let these things go in our waterways FFS
Exactly!
I’ve seen them on the Sunshine Coast qld. In fresh water parts on a salt water system
They are a little tolerant of salt as well so through heavy rain they may move from one body to another if conditions are right.
I use to keep and bred these years ago. Quite prolific breeders and aggressive fish as well.
Yes they look nice but not the best aquarium fish, I had 10 in a tank, they all got killed but one pair that started to breed, pretty aggressive fish.
Throw some Oscar’s into the mix 😂
That will just make it even worse.
I've spotted them in Cairns QLD creeks, living also in the canals through the city. Shocked me amd was sad to see
Yes it's bad for invasive up there unfortunately, the warm tropical climate doesn't help, at least down this way a lot dies off through winter, but a few tough survive.
Are they good eating?
No reason why not, just like any other freshwater fish, probably taste nice smoked, and can be collected as they are only invasive unlike Tilapia that are noxious, the only problem is they are a bit fussy with what they eat as adults being sand sifters, I dropped a pile of live worms in front of them while snorkelling and they ignored them and kept sifting, you may get the odd one, the young readily take the bait though and grow fast, so maybe good for aquaculture.
Some people are so irresponsible.
Yes or just don't have the knowledge.
Is there an eradication programme similar to the one with crucian carp? Does the government know about their presence?
Not that I'm aware of, that is one of the reasons for this video.
They are even thick in every pond in Perth Wa.
Pretty sad to hear, WA is pretty strict with their laws to.
I catch them all the way up the headwaters of the creeks n rivers feeding the Brisbane River.. and in billabongs all thru the forestry..they everywhere :(
Yes I've seen them pretty far up to, they get into every little corner, I've seen them plowing through a inch of water.
What's the fisheries doing to stop the spreading of this species ?.
Gerard.
Not much as far as I know.
Hi Jason, is this the northbrook creek system?
Yes the lower reaches.
It was bad enough when we were dealing with carp and tilapia. Lately (the last 5-6 years) I've been hearing more and more reports of these fish around the western areas of Brisbane. Then plecostomus. Then oscars. I even read reports of peacock bass found near Mackay. Rumors of wolf and jaguar cichlids and red devils are also getting about. We're starting to look a lot more like Florida every day it seems.
I've actually seen the Red Devils in Forest Lake, but you can't fish there, someone showed me a pic of Texans down the Gold Coast, it's really sad, this type of thing will toughen the laws on keeping if people aren't careful, it's getting that way a bit, if we aren't careful we got the perfect temps. here we will be the Florida of Australia.
@@australianbiotopes4563 a big annoyance for me is being prohibitted by various councils from fishing for pests due to "public safety".
@@TheCaptainbeefylog Yes I agree, it's peoples fault though, I used to fish my local lake and they would show a blind eye to it, then people started leaving their unwanted line with hooks and sinkers and unwanted bait behind, they also would lite fires along the bank at night to keep warm, and basically just ruined it for everyone, people started complaining and now they have cracked down on it, once this type of thing happens it's hard to reverse the damage done, now the fish will keep breeding unchecked and overflow into our waterways, I think the local councils need to get onto this if people can't fish for them, it's their responsibility to eradicate them, or it's basically just a breeding program for a noxious species.
Great video but would be good to turn down the background music so we can hear what you are saying.
Thanks for watching! and thanks for your feedback, yes it was a bit loud in this one sorry 🙂
Which waterway was this filmed in?
The lower reaches of Northbrook Creek.
They been around for awhile. 1997 I 1st recorded finding one in a waterbody near Maryborough
Yes I know they have been here for years, but just in the last few years they have become so prolific.
So lures or bait?
I think bait would be better.
More berra would help ?
Yes it would but unfortunately if we have one cold snap in these impoundments they all die as it can get to cold for them, good news is they are releasing a heap of Mary River Cod into the system, but it will take a few years for them to grow.
This is local to me and i had no idea, how devastating
Yes feel free to go and collect some, the more removed the better 🙂
Tilapia have become a major problem in Brisbane creeks and waterways
Tilapia have become a problem in just about every creek from the sub tropics of NSW to Far North QLD along the coastal waterways inland to the Great Dividing Range, this is why I posted this, it could happen with these as well if we're not careful, it's bad enough having one, we don't want another.
There used to be lots of lungfish in that area
There still is.
I am surprised that they can handle the low water temp in winter Wivenhoe dam
They live in the same types of temps. in South America, not the whole of South America is tropical, a bit like our country really.
If they were below the dam, i would've thought that they could've gotten out of tanks in houses when they went under during the floods.
It's sad to know that people have deliberately released them, as they cant get up that side of the dam wall, unless it was from houses that went under in the upper catchment areas.
Not to mention they have been there longer than from the last few floods, the only difference I've noticed is that they seem to breeding much more rapidly now, or maybe there is just a whole lot more that they are being noticed more.
What the name of the creeks and dams they are in would like to go remove them from the waterways
Try the lower reaches of Northbrook Creek rest area, there are heaps of them there.
How can we battle it as fisherman?
The best we can do is to catch them young, they go for baits as a younger fish much more readily than the older fish.
Invasive species are terrible & perhaps impossible to stop (eg. Carp) once introduced. Fish keepers and owners of foreign species perhaps, need licencing. This may pay for education. I'm happy for such, if introduced, as it would be a step forward to stopping such blights
With the amount of floods they’ve had in SE Queensland, I’d imagine a lot of these fish could of entered the environment accidentally
These were around long before the floods, the only thing the floods probably did was help spread them even more.
I removed one from Wivanhoe dam about 6 months ago and have since caught fry(babies) at another dam while visually seeing a breeding pair that I was un able to catch although if I had a cast net that could have been a different story
If I would of been able to use a spear or spear gun I could of got a whole heap of them but just like cast nets they are illegal to use in freshwater creeks that aren't tidal.
@@australianbiotopes4563 I haven't looked into cast net laws I'm from NSW but staying in Qld for awhile so learn something new everyday but yeah next time I'm at this dam they'll be my target species
@@GU-24-WD You can in tidal brackish though, that was like last time I went down to NSW and found out you can't use them down there, they should really change the laws nation wide, it would make things easier.
Box net the creek for 3 years to try deplete the numbers?
I've been trying, I get everything else but them, they don't seem to want to go into traps, you get the occasional one, the young are easy to catch on hooks but the adults are more fussy, as earth eaters, I even threw live worms in front of them while snorkelling and they ignored them and just kept chewing the bottom.
@@australianbiotopes4563can you spear them instead?
@@ladypeiandtheclown5410 It's illegal to spear fish in freshwater or I would of done that, while I was snorkelling you could see how close I could get to them, they weren't afraid.
@@australianbiotopes4563 damn that’s a shame
What we need is a native predator to be introduced to this dam because as we aquarists know big fish eat little fish . There will be obvious decimation to other species but these can easily be re-stocked .
We used to have one, the Brisbane River Cod, but is now extinct , the goo news is they are now re-stocking the Mary River Cod back into the system, they have just not long released thousands of fingerlings, they are really closely related to our extinct cod and I think in a few years when they start to get size to them it will help.
Wow I had no idea😢why are people so irresponsible😢
It may not just be people being irresponsible, it could also be lack of education, some people don't know any better and don't want to harm the fish and think by setting them free is an option, that is one of the reason for these videos to educate, yes there are probably irresponsible people as well, our local fish club has done up a heap of posters to educate people as well and we have as a group started to hand them out to fish stores to try and help this problem, hopefully it will stop it as much as it can, Most good stores will take unwanted fish back as well as an option to be re-homed.
wait till he meets the aussie carp. surprised the bass are afraid of this guy… must be agressive alright.
The carp are just docile and feed the same as them, these even attacked my camera when they had young, I don't blame the bass 🙂
What a shame, if the aussie bass is cautious of these they must be ferocious
We will have to wait and see how they go up agains the thousands of Mary River Cod that have been released into the system to replace the now extinct Brisbane River Cod, maybe it will restore the balance, we can only hope 🙂
How can I get in touch with you?
You can look me up on Facebook, Jason Sulda and PM me, if I don't reply try again as I do miss some, I get a lot of messages.
I've caught at least a hundred of these bastards in my local creek they make it so hard to catch any natives
Yeah it's annoying but better out then in, next time I go out and catch some big ones I'm going to see how they taste, maybe smoke them, the good thing is you can take them home where you can't with the Tilapia.
My fish tank 😂
Good inspiration for a tank 🙂
I just don’t understand why there are not greater restrictions on species the aquarium trade can sell, and why criminalising the release of non native species cannot be reinforced at point of sale. Mum and dad getting little Johnny a fishtank for his room may not have any idea they are doing the wrong thing in liberating the family pet once its outgrown its tank. Educate these people at point of sale and warn of the severe consequences, environmentally as well as legally.
Looks like green terror
Similar but the Green Terror is from the western side of South America, they are both in the family cichlidae but different sub family, apparently they are around in small numbers to in other areas.
Thankyou
Bloody carp of the North 😢
Not quite but getting there, I'd say Tilapia take that roll, still not good though.
I knew that this would happen.
Who let these into the country in the 1st place ??
They have been here for a long time, unfortunately this happens, that's why I made this video, hopefully it will educate people.
I do need new fish for my aquarium
There is plenty out there.
What is wrong with some of these aquaculturists?
Why would you release an exotic pest?
Madness
It's been warm for an extended periot, eventually a nasty winter will knock em out I imagine. Still, idiots dumping Cichlids and taking out the native stuff in the mean time.
These have been here for probably over 20 years and are cold tolerant, they come from South America but the areas they come from pretty much match our climate in SEQ. they probably won't get down further south but if they get into some of the waterways further north there could be more problems, they have just become more prolific in the past few years so they are seen a lot more.
Sadly, there will always be people who just don't GAF about the impact of their actions on the Australian enviroment no matter how much information/education is out there. Is the infestation of pearl cichlids so large it cannot be eliminated?
Pretty much, they are right through the system now, and have been found elsewhere as well, with the amount of young they have and how successful they are, I think we are stuck with them.
@@australianbiotopes4563 🤬🤬🤬🤬🤬🤬
It is sad that people have been advised to limit the fish, they are so beautiful. The activity of the fish and how they protect their young is awesome. It ends with good news, nice to hear that you protect them too.
I don't protect them they are a feral species and do a lot of damage, there is no good outcome, they are destroying the local ecosystem and there is no way now to stop them.
