I have 4 bronzed corydoras and of recent I have been lowering the water temperature and feeding them blood worm more frequently to try and induce spawning. Whilst cutting a few plants back in the tank today I have noticed clusters of black eggs floating on the water's surface and some are also attached to the under side of Echindorous leaves. I was just wondering if these are Corydoras eggs (or perhaps Black Neon Tetra eggs) given the changes I made to their diet and lowering the temperature of the water?
