I've only been keeping fish for about 6 months so I'm not very experienced in this. I noticed that one of my peppered Cories is looking really fat and yesterday I saw Another Cory all over the fat one. Looked like it was riding on its back going crazy. I've see it happen a few times since. Could the fat one be about to drop eggs and the other one is wanting to fertilize them. I know nothing about Cory mating so I'm wondering if it's that. If not. What is going on? Thanks in advance for any help!
