The weather? Cories tend to spawn in conjuction with drops in barometric pressure I believe. I think the fall is the time that they feel most inclined to spawn. Try adding water slightly cooler (2 degrees) when doing a water change, I've heard that can trigger spawning. Also, live foods always help, cories eat blackworms like spaghetti!

If you want to get really into it, I believe breeders trigger spawning by simulating drought and then rain. Something about letting the water level go down and then adding real rainwater or cooler water? I can't remember exactly, but you should be able to find the info around. Here's one article I found on simulating dry & rainy seasons:

I have found that, in my many spawnings of various species, that a water change triggers spwaning. I don't mean the 25% water change that we do weekly for maintainence. I mean a 50%-75% water change!! The fresh oxygenated water is a sign if the "rainy" season for many fish and this is the time that many spawn in the wild.

Good luck with them!

Bob is 100% spot on with his advice. If they're not spawning on their own definitely give the large water change a go. It's worked, inadvertantly, for me many times. :)

Here's another tip which somebody recently gave to me: when changing the water, pour in the new water from a bit of a hight, as the splashing will also help simulate the rainy season.
