Is my corydoras pregnant?

[Nicki Gaga]

I've been feeding my albino corydoras a lot more than usual lately, if this is what you call 'conditioning'. I have the male and female in the breeding tank and the female is eating constantly. When do you think I should do the cold water change and at what time? How long usually before they start breeding after the water change? Thanks.

I "accidentally" successfully breeded/produced corydora. They have been producing eggs every year, usually in cold season of the year. Last year, I noticed tiny creatures swimming around the bottom of my tank. Turned out that these are new hatched corydoras. I just let them since I don't really plan to breed. There were probably 100 of them and only 1 survived. It's about 1.5 inch now.

To answer your question, I don't think your cory is pregnant. They really like to reproduce/copulate in cold temperature. During summer is highly unlikely. I could be wrong. Just do water change as usual. I still did 25% water-change every week even when there were eggs all around my aquarium.
