Breeding Corys

[vix]

Do cories have to be their full adult size before they will spawn?

I have a nice variety of corys and none of them have ever spawned, would love some baby waby cories

It all depends on the species. I've had very young bronze cories spawn, only a few months old. Another forum member has had her peppered cories spawn at like 6 months old.

I got some Trilineatus last week which I am sure are not mature yet, and they spawned within 2 hours of being introduced to the tank. But, I've heard that Sterbai have to be mature to breed.

What types do you have other than the albino C. Aeneus you had pics of the other day? How many of each species have you got? With some species you have to condition them and trigger spawning. Others are easier, it just depends on your setup. Have you got them in tanks with other fish? Plenty fish are egg eaters and unless you actually see them spawn and are able to collect eggs, you'd never know because they get eaten.

Hope this helps.

I have albino cories (8 of, although 3 are a lot bigger than the others), 4 panda cories, 3 peppered cories, and 3 trili. I am planning on increasing the number of pandas and trilis. At the moment the abinos and pandas are in a tank with a few guppys and some praecox rainbows.

Hi Vix

I wouldn't be surprised if your albino C. aeneus and peppered corys (C. paleatus) spawn at an earlier age than the others. Their spawns might be small though, but will increase as they mature completely.

If they feel safe, I don't see why they shouldn't breed. What are your tank stats and the size of the tank? What do you feed them? Are the rainbows aggressive, or do they just ignore the cories (I don't know much about rainbows)?

It also depends on whether the cories feels safe in their numbers. I have 5 pandas and it took them ages to spawn, but only 4 Trilineatus, and as I said previously, only 2 ours and they were at it. We had our bronze cories about 4 months before we noticed a tiny cory and only then did we realized they were spawning. They did tend to hide their eggs, but once we were hunting around for eggs, the females would lay them on the glass on the front of the tank.

The rainbows are very peaceful fish, they ignore the cories, i am water changing daily just to keep the tank as clean as possible. Stats are 0 nitrate is 20. Out of the larger of the three albinos i think i have 2 females and a male.

Out of the larger of the three albinos i think i have 2 females and a male.

I think that could be the reason. It is always better to have more males than females. I have watched how two males will pursue 1 female and both hound her down, trying to spawn with her before the other male gets hold of her. They also seem to escort her to where she is going to lay their eggs so the other male can't get in there . It really is very cute, but they do need competition to get them going. Are any of your smaller albinos resembling males?? Are they in a separate tank?

It's not really necessary to have more than one male for spawning, but if you have more of them the fertility rate of the eggs will be higher.

It is very cute to watch them spawn. The males like to chase the female and even swim right in front of her face like they were saying, "Pick me, pick me!" The she makes up her mind and pushes one of them over on his back. I wish I could get a picture of my pandas in the T position. They like to do it in the middle of the water, not just on the substrate.

ok ty for your helpful replys. Seems i could be witnessing some spawning behaviour as my large male chases one female everywhere, but shes having NONE of it picky lady . The smaller albinos are in the same tank, but i'm rubbish at sexing lol. Can post some pics if that would be of help.
