How can I tell if my cory is pregnant, overweight, or just a healthy girl? Is there something I can look for aside from eggs popping up? She's always been a big girl but she seems to be a little bigger lately and I don't want her to have babies in the community tank. I can't get a good enough pic of what her belly looks like to post. Can someone post a pic of what cories look like when they're ready to breed?
