Bronze cory eggs?

Thanks :D however its been months since the last spawn, and althought the male has been at the female, there is still no eggs. i dont think there has been any changes in the tank since the last spawn. any ideas on why they havent spawned?

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.
