I wanted to breed my green laser corys and wanted to know how to and how to differentiate the males and females. I’ll really appreciate the help and info
Thanks a lotWe've got several Cory nerds here! I'm a mere amateur compared to some of them, but I can help!
The main way to tell is that females are larger and more plump, while males are smaller and streamlined. This is only reliable once they are a couple years old though.
The other way to tell is by their pectoral fins. Females have scoop shaped pectoral fins, while males are more pointed. Googling some pictures will give you a better idea.
