Corys will lay eggs anywhere, often on the glass, but also on the gravel, around or on plants, on the filter or decorations like rocks...you name it.

For this reason it is often best to breed them in a tank of their own or be ready to remove all the other fish from the tank they spawn in. It's also a good idea to have them in tank that is set up just to breed them so you can have no gravel. No gravel means you can keep the tank cleaner as you raise the fry.

To keep these fish you should 1st make sure that they are is a group of at least 4, but more is good. The females are generally larger than the males, so when buying them maybe get 1/2 larger and 1/2 smaller, if there is any difference yet. Also keeping them in shoals means you'll almost deffinatly have a pair.
To get them to spawn make sure their water parameters (pH 6-7.5 and a low to medium hardness and clean) are optimal and then do a 20-30% water change, but use cold water. The change in temperature will tigger spawning. They will sometimes spawn without doing this, but this increases the chances.
If they spawn in the community tank, just take out all the other fish and feed the fry once they're free swimming and make sure that you cover any filter intakes that they can get sucked into

After spawning take the adults out and start to feed the fry once their yolk sac is absorbed. Fry will take crushed quality flake, but live foods like "chopped" black worm, micro worms and baby brine shrimp are less poluting.

Good luck with breeding them.

hello

thx for reply,

I found about 15 eggs on side of glass, which i scraped with razor blade into a small breeding tank which i attached to main tank glass, (i had read this on web, scraping eggs off with blade)but after about 3 days the eggs appeared to start growing some sort of fungus/ mould on them!

this morning i have about another 15 eggs in roughly the same area as before, what do u suggest i do now, so i can hopefully keep theses eggs alive!

thx
lee

Scraping the eggs off glass is very delicate and rarely works. Scraping the eggs off (touching them) could be the reason they got fungus. Another reason they might have got fungus could be that they weren't fertile to begin with.

If you want to try and hatch this second batch of eggs, I suggest you leave them where they are and try and move all the fish to other tanks.
If you leave them alone and they get fungus, you will be able to determine that they weren't fertile and may need to question whether you have a pair or not. A female will lay eggs without a male...obviously these are never fertile and will get fungus!!

The bigger problem with raising the young in the main tank is finding them and feeding them, this is always easier in a smaller bare bottomed tank.
Maybe look at keeping your corries in a seperate tank if you want to breed them.

Hi mazz,

I really am not 100% sure of the age that corys become sexually mature, but females are larger than the males and they get fat when they are ready with eggs!!

Becaus ethis species is very social it is always best to keep corys in groups of 4-6 (minimum)....more is good!!
This way you will always have a few pairs too.

I know this is an older thread, but I want to jump in somewhere~

When I bought 2 Julii Cory's a couple of years ago, for my 20 gal Mystery Snail tank, I didn't know they were a pair! When they matured the female started laying eggs on the glass every time I did a partial water change! I'm sure everyone hatched!!

I also had a Pleco in there and he would clean up the eggs. Took him out and pretty soon had umpteen little Cory's swimming around.

I just left the eggs on the glass and they took care of themselves! I was soon overpopulated and had to separate them out!

You should scrape the eggs off the glass with a razor blade and put eggs in a container in the tank with the parents with an air stone and add methylene blue just enough to see the light blue colour to stop the fungus eggs are white then in 2 days the fertile eggs will change colour depending on the corys.The reason for this is i have eight corys in one tank and as soon as mine lay eggs its like a frenzy with the corys that arent involved to eat the eggs.I mean seconds theyre like bears to honey.

Leave the eggs alone, my corys keep breeding and the fry are great. I only have a dwarf gourami in my well planted 20 gallon tank. Other fish will eat the little ones

To avoid mold try getting air in there with a bubbler or somethong to keep water circulating

Hello firstly I would like to say I have found this site most helpfull, secondly I have yesterday found 56 and lost count now tan colured eggs on the glass, my two Cory in the tank are albino and brown so I must have been just lucky to choose which two to put in this tank, they seem happy enuff and share the tank with a plek a male siameese and his 5 girlfrinds all who get on very well so hopefully that puts to bed all the dought about siameese, i agree only 1 male is correct. So going back to my lovely eggs which I believe after reading here if tan are maybe fertile.

When you post a comment, look at the dates of the previous posts - if they are old, you should start a new thread. That being said, cory eggs are fertile as soon as the female lays them. If you see that the eggs are turning "white", that means they have fungus on them and will not hatch. If the eggs have flowing water near them, they will be more likely to hatch. I'm actually surprised the parents have not eaten them! Here is a blog I wrote that might help you: http://www.myaquariumclub.com/how-to-raise-corys-the- easy-way-from-egg-to-adult-3467.html

Thank you Im new on here and have started a new thread as you sugested I think she very cleverly found where the pump blows out to hits the front glass and put her eggs directly in front of it, secondly the siameese dont go near the current and so they have left them alone as well, day 3 and all eggs still tan coloured and still 56 of them so fingers crossed and once again Thank you

If you've got a male & female they will breed. We now have 6 generations in our tank with other types of fish. We do not control the eggs. They typically survive in pairs. New fish show up about once a month or so. Our tank is only 15gallons. Petco will adopt fish.
