Breeding Cory cats

[plecoman]

Has anyone had good luck breeding cory cats?

I have never bred cories but have heard the following:
High male to female ratio and a partial water change of significantly cooler water can trigger a spawn.

Like more guys than gals?

Do you know if there's anything you have to add to the tank for them to breed in, or will they just lay their eggs on anything available? I've known of them laying their eggs on the tank wall's, but I was wondering if their was anything that they really liked that might also help?

When I moved my 55 a few years ago, had to pull about 80% of water to move it. They did lay then. Was completely supprised too. Haven't had it happen again. Even tried a huge water change again. Don't know what was special that time. Any ideas I'm up to give it a whirl.

Mine spawn kind of hit or miss. They used to lay eggs frequently but haven't in a long time. I think the plecos or angels might eat them. A water change would usually trigger the spawning, and eggs would be everywhere--tank walls, plants, etc.

I do not believe that you need anything special in the tank. River11 was breeding cories in bare bottom tanks. Have you conditioned the females with plenty of frozen foods?
Note: The purpose of the partial water change with significantly cooler water is to simulate the start of the wet season in the wild, which is also the start of the breeding season - that is what I have been told.

It works with jewels! I don't doubt it.
