Hi mark ive recently mooved to a boarding school and done my first nano aquarium with an amazing aquascape in school its so much more less boring now 😂. Your vids are great and inspiring.
love ottos! cool looking and super chill fish that help balance and clean a community tank. great fish. thanks, mark! looking forward to another video!
Wow thats beautiful. I got 8 in a planted 300 liter tank with tetras. Don't see them too often unless they come out and sit on leaves of plants at front. Or I turn on room light at night. Lovely little fish. 👍👍
How is it going Mark :) Hope you and your fishes are all good. I would love to see one of your old school videos again. You know, diy, guppies and swordtails ;)
I hope I can meet you one day @marks aquatics you have taught me so much and have been my inspiration from day one. I really appreciate all of your hard passionate work you put into this hobby and RUclips. Thank you
One of my favourite fish well done its so nice to see that it can be done if only more people could then less could be taken from the wild . I personally would love to see you breed khuli loaches if it's at all possible .look forward to an update when they get a bit bigger thank you for taking the time to share your success xx
Very late to the vid , I love ottos , I found the recent cory fry ( happy little accident ) I had loved to sit and feast on that same sponge you have on inlet it was crazy seeing them all useing as a bunch of shelves
Quick question to Marks aquatics I just purchased 5 otocinclus catfish, They don’t want the algae wafers I’m trying to feed them, What should I feed them? Also great video eventually I’ll try and breed some 😊
I second the zuchinni although I dont blanch them I just weight them down with a rubber band and a rock. I always make sure my herbivorous fish have some zuchinni, yellow squash, leaf lettuce for them to eat
Sometimes it takes a day or 2 before they start to eat food they don't know yet. So the wafers might still work once they know it. I have most succes with a slice of cucumber but again it might take a day or 2 before they really start on it to eat. And peppers like Mark said are also good.
Awesome video. Thank you so much for the series…I really enjoyed it. Recommend Denison barb for your next project. I hear they are impossible, but I recently saw two stores selling tank raised ones.
Hi Mark, sorry to jump in on the comments section regaring something a bit off topic, however I'm looking for expert advise on controlling a nitrite spike (max reading has been 1.5ppm). 5 days ago I purchased some longtail Panda Corys which unfortunately developed finrot after 48 hours. Within 2-3 days 1 had died, the 2nd died approx 12 hours later, the 3rd was returned to the fish store who were already aware as they have had several reports of the same thing with this particular batch of fish. The issue is that the dead fish was totally hidden away rotting in my tank for around 2 days (unable to find it until today!), and I stated to notice a few Cardinals were surface breathing and my water was clouding up. I treated my tank with finrot treament (half dosage) proir to the clouding then also discovered that the Nitrite had started to rise from zero (I perform daily water tests for 3 days when introducing new fish), however at no point has my Ammonia been anything but zero - which my specialist fish store confirmed on a sample I took in. I started with a 30-35% water change (Nitrites then reduced from 1.0 to 0.5ppm) but within a few hours when I did my next Nitrite test it had gone up to around 1.0ppm again. So I repeated with another 25% change (each time treating the tap water with API quick start to remove the chlorine), however after a few hours again the Nitrite climbed up to 1.0-1.25. I then stayed up all night monitoring the Nitrites every hour, performing another 30-35% water change at 3am this morning, by 7am my Nitrites were 1.5ppm and the fish are stressed out. At this point I've performed 5 partial water changes and the Nitrites keep creeping up and I'm very worried because I have 3 rare plecs and no spare tanks or spare cycled media to combat the bacterial bloom...2 Cardinals and a Glowlight Danio have died so far* Speaking to a local expert he has advised not to treat my tank with Prime (water conditioner) and a new bottle has just been delivered by Amazon - do I treat the Nitrite directly with the conditioner or as I've been advised, will this potentialy put me in a worse position by increasing the toxicity threshold of the water? My water is still cloudy, still around 1.0ppm Nitrite / 0 Ammonia, Nitrates are approx 0.5ppm in a heavily planted 400L tank. My head is telling me to treat the tank with Prime because the fish cannot sustain this for long and I have 3 rare & expensive Plecs that I'm terrified about losing. Please help me :(
Hi Mark I've followed your channel for some time now and I wondered what you use, if anything underneath your tanks to cushion them against uneven surfaces, etc. Regards Ian
Hi I don’t know if you can help me but I bought a pair of clowns 1 week ago, added them to quarantine treated for internal parasites and after a couple of days they were eating, doing 10 percent or less water changes every other day and then when I did a larger water change and added 2nd treatment last night, they have stopped eating today... acting normal swimming but look a little scared and stressed, maybe because of the treatment and heavy water change they are stressed? Any ideas?
I’ve one of the fattest lil fatty arbuckle female ottos I’ve seen, plus 2 or 3 lads. Now would she probably be laying eggs in the Kubotai tank and maybe they’re just getting eaten or what not OR are they too hesitant n scared to lay in a busier tank? I could remove the, into a diff tank for few weeks to see? Have you don’t Borneo Sucker/Hillstream loach breeding? I’d luv to see you do the striped Borneo suckers. THEN I can learn n have a go 😉🤪😁💙
Mark you make it look so easy! You've only just started this project and it's already taking off! Do you have any tips for foraging sources of infusoria, copepods and such to add to a tank?
hi Mark how do you get clean water for water changes for years I've been filling a few 20Ltr drums from the tap adding pond declorinator and a air stone and leaving it min 2h max 4days it's not working for me any more I live in NW pennies and they are using chloride now not chlorine and I think the declorinator is converting the chloride to ammonia I need to figure out what to do over the last 2 years I've had so many tanks crash and lost a lot of fish I have been close to giving in I've all ways gone with if something seems wrong in a tank do a few big water changes but if the new water smells like cat pee what do you do😥
Im in the process of setting up a small fish room to breed my2 favourite fish, chili rasbora and galaxys! your videos have been very inspiring. You are a wealth of knowledge for us and we all appreciate you making these videos. Can I ask any tips for keeping your fish room? I have an outside shed thats enclosed but do you heat your shed or just the tanks? Ob viously were both similar climates so wondering whats most effective
So happy when I saw that this video was just posted!!!
Well done Mark, i have posted this video on my Otocinclus Catfish Group on Facebook, i hope it helps the followers.
Hi mark ive recently mooved to a boarding school and done my first nano aquarium with an amazing aquascape in school its so much more less boring now 😂. Your vids are great and inspiring.
Wonderful series! I've loved otos for decades, but never thought breeding them at home was possible. Thanks so much for showing us how to breed them.
Is there a part 4? How well did they grow up?
Thank you documenting this! Love seeing how they progress :)
Mark, why have you stopped posting? When I first started breeding fish you were my guiding light!
Sadly the electricity bill got so high I had to really down size . Hopefully get going again soon.
Hill-stream Loaches would be fun to watch grow as they change shape so much.
Same for Corydoras. However, this Oto breeding series is far more interesting!
Good Job, great little series.
Thank you for keeping us updated.
I hope you will post their progress with us please. 😊
woop woop, well done mark!!
Great videos mate, straight talking no messing and making it look easy 👏
love ottos! cool looking and super chill fish that help balance and clean a community tank. great fish. thanks, mark! looking forward to another video!
Always good to see some wrigglers. I still get delighted when I see live bearer fry never mind egg layers. Great job Mark 👍
I enjoy watching the videos you make...
Wow thats beautiful. I got 8 in a planted 300 liter tank with tetras. Don't see them too often unless they come out and sit on leaves of plants at front. Or I turn on room light at night. Lovely little fish. 👍👍
You're always successful at breeding the more difficult fish, and I always learn tips, and tricks from you. Thank you for sharing your knowledge.
👍❤👍
How is it going Mark :) Hope you and your fishes are all good. I would love to see one of your old school videos again. You know, diy, guppies and swordtails ;)
Captive bred ottos!!! Keep up the good work!
absolutely amazing Mark 👏
Impressive! Never tried but I always thought Otos would be harder to breed... Or maybe you're just brilliant at it :)
Did the fry survive? Seems like people are able to get the otos to spawn, but raising the fry is that hard part.
Just another amazing project and as always completed with a big success. Very nice videos you are making Mark, keep it up!
Aaand... he's back! Lovely vid yet again.
Can't wait to watch this when I get home n get in my jammies
I hope I can meet you one day @marks aquatics you have taught me so much and have been my inspiration from day one. I really appreciate all of your hard passionate work you put into this hobby and RUclips. Thank you
Thanks for watching 🎅👍

Where is Mark?
Awesome Mark 💕
When is the update???? I've put my RUclips notifications on just to see your update
Brillian stuff , it seems you get most fish to breed Mark.
Very late to the vid , I love ottos , I found the recent cory fry ( happy little accident ) I had loved to sit and feast on that same sponge you have on inlet it was crazy seeing them all useing as a bunch of shelves
Quick question to Marks aquatics
I just purchased 5 otocinclus catfish, They don’t want the algae wafers I’m trying to feed them,
What should I feed them?
Also great video eventually I’ll try and breed some 😊
Try blanched zucchini, make sure to take uneaten out after a day, also having lots of natural algae build ups in the tank helps
I second the zuchinni although I dont blanch them I just weight them down with a rubber band and a rock. I always make sure my herbivorous fish have some zuchinni, yellow squash, leaf lettuce for them to eat
Sometimes it takes a day or 2 before they start to eat food they don't know yet. So the wafers might still work once they know it. I have most succes with a slice of cucumber but again it might take a day or 2 before they really start on it to eat. And peppers like Mark said are also good.
Spiralina tablets, bacter ae, bell pepper, Indian almond leaves
any more native aquarium vids on the horizon?
Probably next spring now.
Amazing Mark, thank you!
Are they still alive, and if ...how big are they now ?
Awesome video. Thank you so much for the series…I really enjoyed it. Recommend Denison barb for your next project. I hear they are impossible, but I recently saw two stores selling tank raised ones.
Awesome
Wow. Congrats mark…they are really jittery swimmin lil guys aren’t they…

Fantastic!!! i hope you're going to breed pangio some day!

Hi. I use underlay for under wooden floors.
it's been 4 months now , have they survived?
Nice update. How many are there?
About 6 🎅👍
Hi Mark, beautiful what yo have done with these otos. I'd like to know the kh and gh of this tank ?
Nice video Mark. Next fish to breed Nannostomus mortenthaleri.
I' m breeding them succesfully.
Great to see them hatching!!!!!! K
Congratulations Mark, another fantastic success, gg. Have you ever tried to breed Bumblebee Gobys?
Happy New Year Mark!! Hope your okay! hoggie UKaps.
Hey Mark I've lost you on fb....don't know how that happened hope your well.
Amazing video Mark really exciting!
Are you planning on selling your little vegetable holders I’d love to get one?
Is there any fish that won't breed for you? Lol. Amazing 👍
Brilliant. I am a huge fan of your work. Did you remove the adults?
Hi I don’t know if you can help me but I bought a pair of clowns 1 week ago, added them to quarantine treated for internal parasites and after a couple of days they were eating, doing 10 percent or less water changes every other day and then when I did a larger water change and added 2nd treatment last night, they have stopped eating today... acting normal swimming but look a little scared and stressed, maybe because of the treatment and heavy water change they are stressed?

Hey Mark, its 2022 Haven't heard from you this bew year yet. Hoping you are well. Hope to hear from you soon.
Hope all is well, noticed you haven’t posted in 2 months.
after watching this I have just got 6 otos
You are a phenomenal fish breeder Mark, is there any fish you've had difficulty trying to breed?
Would like these to start becoming a tank bred species. They'd be less fussy eaters no doubt, if raised on a commercial fish food diet.
I’ve one of the fattest lil fatty arbuckle female ottos I’ve seen, plus 2 or 3 lads. Now would she probably be laying eggs in the Kubotai tank and maybe they’re just getting eaten or what not OR are they too hesitant n scared to lay in a busier tank?

Do you have any tips for foraging sources of infusoria, copepods and such to add to a tank?
Haven't seen a video in awhile. Hope everything is OK. Prayers to you and your family
All ok. Just had a break from it all.
Don't blame you. Just know you are missed.
