Breeding Corys

[timmystood]

I've looked on the web for some info about breeding corys but the only info i've found is useless to me.
Could someone tell me the best way to get corys to **meet each other! in a special way!**
??

Cheers

Please try to ask questions in the right forums.

Inchworm is the resident Corydoras expert and has successfully bred many species, this question asked in the catfish forum would get faster reply.

I got mine excited by feeding them lots of live food (well, TetraDelica bloodworm, to be exact) for several days. I also did a partial water change adding cooler water (simulates onset of rainy season in Amazonas)- not sure if this was necessary. I really don't think anything essential was added to this by my husband flashing a torch at them and shouting bang bang (imitation thunderstorm).
I have to be honest and tell you that though they spawned enthusiastically, I did not succeed in getting any eggs to hatch; they ate most of them and some of them were not fertilised. Maybe mine are a bit young, and I probably need more males (ideal ratio 2 males, 1 female). Still, they were great fun to watch and clearly enjoyed themselves.
Inchworm will be able to tell you more.

I read that you can add ice cubes to imitate the rain

Hi timmystood

I'll be happy to help you get started breeding your corys, and there are a number of other members who already have batches of cory fry, and will help you too.

If you have male and female, bronze and albino C. aeneus. and if they are mature, healthy and well fed, it's not hard to get them started spawning. If they meet that criteria, it's even possible that they have already spawned but the eggs have been eaten by the other inhabitants of their tank.

But let's start at the beginning. Do you have males and females? Are they full grown, or close to it?
If you don't know but can post a picture of them, looking down from the top, perhaps we can help you figure it out.

Here are some pictures I took last night and this morning. They show some corys that spawned during the night and then their eggs.

Here's the first one. What I was in the middle of doing when I took it, was moving some fish from one tank to another. I had just sold a batch of bronze and albino fry to the lfs and was cleaning out their tank. I plan to use it to house corys that like cooler temperature and this one will be kept at around 72 degrees F.

I took this picture because I had enjoyed watching them play in the waterfall caused by the filter. They were really getting tossed about and enjoying every minute of it.

I filled up to about an inch of the top, planning to finish arranging the tank today. This is what I found when I woke up this morning:

I hope the picture shows the eggs because it came out very dark. I believe that it was the bronze corys that spawned because the others, C. robinae, have never spawned for me before. I've never seen such a quick response either. These fish were not conditioned in any way. If they had been, there would have been many more eggs because these are some very big wild caught corys.

Hi timmystood

I hope you haven't been put off by some of the responses on this thread. Getting corys to spawn is usually not very hard at all. Many times, bronze and albino corys spawn even if you do nothing special to encourage it. The challenging part is raising the tiny fry to adulthood. We can help you with that too.

It's a lot of fun, and I hope you are still considering doing it.

My cories have spawned 2 times now with just regular weekly water changes and regular feeding (flake, hikari sinking wafers, tubifex worms). So its not hard to get them to do it. Ive learned a lot from Inchworm and raising this first batch I have, so we can definately help you in you need it. I have really enjoyed raising them thus far and cant wait until they get full grown and start the next batch.

Good Luck
