Pregnant Bronze Corydoras

[nick1200]

So i have 8 bronze corydoras in my tank and i have had them for around 8 months now and have noticed some of them getting fat and there belly turning white and then around a few weeks later they go back thin again. Today i have noticed two of them have gone huge and they are chasing each other around the tank. Also they seem to be jumping in the sand if that is posable  i know that they like to play in the sand but there doing it more often over the last few days. Im just wondering how long till the bronze corydoras will lay ? So i can keep a eye out for the eggs..

The males will chase the females a few hours before breeding.  A cold water change usually triggers breeding.  Sometimes it's just the males getting antsy though. They should spawn in the next few days if the females are gravid.  When you see them making a T shape get ready for loads of eggs.  Good luck!
