I was cleaning my 125 gal. tank today and I found a Cory Catfish fry. I was very pleasantly surprised, but shocked. I never thought my Cory's would reproduce in a community tank The tank has tetras, a few platys and mollies, one angel fish, Glo Fish and a 10-12 inch Pleco. My questions is, is it common for a cory to reproduce in a community tank?
