Out of all the videos this by far was the best one. Each step is clear and I’m not left with any questions at this point!!! Thank you! Also very entertaining. You are awesome!
I breed guppies, but I have a small group of emerald corydoras. I've had them over a year and suddenly they decided to lay around 200 eggs all over the glass 3 days ago. never planned to spawn them and I've never dealt with fish reproducing that weren't live bearing, I managed to save around 60 eggs that weren't eaten or dropped to the bottom which I couldn't reach because I'm freaking short, so I suppose the guppies got those also!!! anyway they all hatched this morning. no kidding I have around 60 microscopic corydoras in a sterilite container with an air stone. thank you for your video because I really didn't know what on earth to do with them. I never used the methylene blue I just transferred them and I only had one egg turn white and I tossed it to the guppies. I'm so happy!
Ashley. The methylene blue is not a must. The fact that almost no eggs turned white means your Corydoras are very fertile. Congrats on your eggs hatching. Just remember this is only the beginning of the battle to keep them alive until they are big and strong enough. Daily maintenance is crucial. 👍
@Seamus hey I think you're right.. in my tank I have Cory's, guppies that continue to breed non stop, and some Otocinclus and it's well planet. a few nights ago I bought some new pellets for my bottom feeders but I noticed they were not eating them like the ones I had before.. it was late at night so i siphon the water out so they wouldn't contaminate my tank from over feeding. This is a 55 gallon and I think I took out 2 or 3 gallons.. now 2 days later I get all these eggs all over the tank.. so now with your theory of the rainwater I wonder can it work in reverse when you take water out. What's your thoughts on that? And still now I haven't put the three gallons back in yet the water level is still low.
Yes, that's a very good point that I did not address in the video. If your room is quite cold you will need to either transfer the water very slowly into the jar to avoid sudden temperature change, or if you have a warm room you can keep them there, or you can use a bigger size container instead of a jar and use another heater. Thanks for bringing up an important point.
i tryed doing all the stuff to encourage them to breed lowered water level dropped temp etc nothing happened that was a week and a half ago today they started breeding and eggs all over i have collected around 30 i know there are still lots on the leaves that ive not managed to collect yet, the only thing i did was turned up the temp a touch. i originally put them in a breeding box until i watched this video so they are now in there own tank with a RCS that apparently eat any fungus..anyway thanks for the video it really helped me.
Thank you for this detailed information. Nature doesn't have a 100% success rate. Don't be so hard on yourself if you killed some eggs. They are just eggs
Hi I was just wondering, I've got some eggs in a separate container with an air stone in, I'm doing water changes but just wondered about the temperature difference between the main tank and the container the eggs are in.. I can't get a heater in the separate container and didn't notice one in the video, does this make a difference? I appreciate this video is years old but of any one has any info that would be great! Thanks in advance.
Brilliant video 👌 very well explained! I'be just got some black Venezuelan corydoras that look like they're displaying breeding behaviour, that's why I came here!
hello! what are the chances of success if i let the eggs in the same tank they appeared? i saw this morning spread around 7 cory eggs 😅 it’s something new for me…
great video, do you continue to use methylene blue after eggs hatch, for example, do you use m-blue for a few weeks after hatching to ensure the fry survive? thanks!
My Corys spawned yesterday... It's not the first time they have done, but I was misinformed and didn't have any fry develop from eggs. With this help I am sure to get them to hatch. If I do there should be a video on my channel soon :)
I bought 3 panda cory doras about 3 months ago and they laid a lot of eggs all over my tank. I took the eggs out and put them in a jar and 10 eggs hatched. I dont know what to do now. I have a lot!! 🙃
Its actually easier to lower the water level, and then carefully remove them one by one. I set all the eggs on a small clean piece of plastic (yougert container lid), and then put the lid into another tank. Previously have tried smsll containers, smsller tsnks etc- but the best is really another tank. Currently using a 16 gallon plant tank for peppered cory eggs, with HOB filter, Sponge Filter, Airstones, and lots of Wisteria. Fortunately some eggs were laid on a Wisterisa plant pot, so just moved the whole plant! 20 or so bebes now, hoping for the best.
Good day, thank you so much for this video as I was afraid it was ICK. Anyways, how should we regulate the temperature in the jar. We keep the house around 72 degrees and sometimes warmer, sometimes colder. Will the water changes keep the jar at a safe temperature?
The eggs should be able to endure slight temperature change. Just make sure you change the water gradually and that the room temperature is not too different from your main tank water temperature.
@@mandy1339 Thank you once again; Unfortunately, my last stone crumbled and so I have a tube in there with just the slightest airflow to create smaller bubbles. Now we wait... Many thanks again. I am now a subscriber and I hope to see more!
I got a question... how do I clean out the uneaten food and poop from the bottom of the fry tank? They’re so small I can’t suck it out with an airline cause I’ll suck them up. I don’t know what to do
I used my turkey baster to remove the eggs and I have 75+ fry from two batches of eggs they're 12 days old today so you should really consider the turkey baster it worked wonderfully
Turkey baster seems to be good for cleaning up too. I got the fluval/marina hang on breeder basket and really love it . It has a hose to control flow of clean water from main tank or disconnect and just use air stone for methyline blue treatment 💙
Hello I have a 2.5 gallon and around 100 eggs should the filter be on and should I have decorations sorry I'm late but I wasn't planning on them having babies please let me know asap thank you Edit1: none of them made it but they just laid more so fingers crossed Edit2: unfortunately fungus spread to all of them Edit3: they made it!!!!!!!! I have 1 day old baby fry I'll keep updating
Hello. Only the sponge filters are safe for the fry. Anything that suctions hard will swallow the little tiny newborns and they will die. Hope it helps
Thank you. My Cory fry is a couple of days old. I am feeding them crushed flakes that I make really fine. Is that ok? Also do I still need to do the daily water changes in they are in their own tank?
You are welcome. Make sure the flakes are very very fine. If you look very closely you might be able to see the food through their transparent bodies which means they are eating. Crushed flake works but make sure it is really really fine. As far as the water changes, how many gallons is the new tank? is it cycled? If it's a cycled tank of about 5 gallons you might not have to do daily water changes, but you should still check your water parameters frequently. The fry are very susceptible to water without ideal quality.
Thank you very much. Yes I crush them very fine. The tank is 30 l or 7,9 US gal. It has a hob filter and temp is between 24 to 25 deg. I still have the male Corys in there. 2 of them the female passed away last night after she laid more eggs. Should I remove the males to the original tank? Ps I had no intention of breeding but after she laid eggs I had to protect them from the communal tank.
Rajeev Devalall yes you should remove the males from the fry tank. It is very important for you to know what it means for a tank to be cycled. If the tank where you have the fry and the males is not cycled it will be dangerous to all the fish in there. Something you can do to help with that is to bring a sponge or rocks/plants from the main tank into the fry tank. The males should be removed now because they could kill the fry.
Rajeev Devalall ideally you want to measure parameters such as the amount of ammonium and nitrite. Those are the 2 most dangerous to your fish, and unless the tank is an established tank with beneficial bacteria already living in it, ammonium and nitrite will build up quickly to deadly levels.
I have 125 gallon tank And I find 4 babies cory in my tank I have 3 cory that are blue 2 cory are yellow, and I brought 4 more of the cory that was blue.
I bought a special mesh basket from a pet store to hatch the eggs in. They told me that baby fish couldn't get out of it. They lied. All buut one got out of the box and the adults ate them.
mandy1339 las mias acaban de nacer pero es difícil cuidarlas; las tenia en un contenedor y las acabo de pasar a un breeder net pero se murieron algunos :(
@@nidiarivers4954 es posible que la diferencia en temperatura les hizo chock. Es normal que mueran algunos alebinos. Solo haz tu mejor esfuerzo. Buena suerte!
Hello, they need the water to not be too deep, but it can be deep enough to fit a heater if needed. They will swim to the surface well enough where the water doesn't have to be too shallow. Just make sure it's not too deep. Also, some heaters can be positioned sideways inside the tank. And if you are using a jar for the first week or two, you can get by without a heater as long as the room temperature is not too cold. Hope that helps
@@mandy1339 wow thank you for getting back to me so fast! I got a week old baby albino corydora and a handful of eggs I rescued yesterday. I have been feeding the hatchling liquid fry food and a bit of powered shrimp. Here in the UK I keep the house around 19 degrees Celsius, hence my question about keeping the water warm :)
i leave my eggs alone and let nature do what it does. I usually end up with at least one live cory each spawn. The population is growing fast enough lol

Wow amazing wideo bro. I got fish tank for about 2 months and already found eggs! Now took them out and i AM gonna do what you did. Very instructive
Best overall video of care from egg to first feeding out there. Thank you.
Thank you!!
Very good information! My cory's just layed eggs and this video is all I need! Thank you. Dale!
I'm glad it was helpful!
This is great very entertaining with the tape cuts you should make more videos
I just used the squeeze type syringe to knock them off of the glass and suck em up at the same time. Thanks for the great vid.
Finally, someone who doesn't have 20 tanks to use geeze. Gonna try jar method. I really wasn't planning this lol.
How do you keep the the jar with eggs with good stable temperature..? Wouldn’t the temperature drop since the water is in a jar?
Yes, that's a very good point that I did not address in the video. If your room is quite cold you will need to either transfer the water very slowly into the jar to avoid sudden temperature change, or if you have a warm room you can keep them there, or you can use a bigger size container instead of a jar and use another heater. Thanks for bringing up an important point.
Very simply explained step at a time . Thank you
By doing in this in a jar outside of the tank, will the fry be okay without a heater? Or must they have a heater at all times?

Hello. You don't need to re-apply the Methylene Blue.
Very helpful video.Thanks.
thank you that was very insightful
If I only have Corys in the tank, can I leave the eggs inside the tank and not remove the eggs to put in another container?
Hello John, You can leave the eggs inside the tank but the Adult Corys might eat the eggs/newborns.
My Corys spawned yesterday... It's not the first time they have done, but I was misinformed and didn't have any fry develop from eggs. With this help I am sure to get them to hatch. If I do there should be a video on my channel soon :)

Tell me your secrets I am trying to breed mine
Take them to your fish store, they may give you money or not, it depends.
@@unoriginal1086 most of the time your local fish store wants the Cories to be around 1 in length before they will accept them in
You should sell them to your local fish store

If the fish in your community tank are not aggressive, then you can transfer them as soon as they don't fit in their mouth.

Sorry to hear that. Yes cory fry are sooo tiny. The mesh needs to be very fine.
Thank you!
Do you use methalyne blue everyday until eggs spawn?
No, just apply once at the start. And with the partial water changes it will start clearing out
A faster and more efficient method of removing the eggs is using a flat razor head to scrap GENTLY scoop them right off the glass
Credit Cards, or gift cards work well too
That's true, but I didn't have success with those methods.
