-Thank you!
ps-I know the females bellys are a little bigger, but what else?
It can be pretty difficult to tell them apart. But from my research I found that Males tend to have pectoral fins that are longer then females. Males also tend to have firmer stomachs while females have softer stomachs. In general, a lot of female fish end up being bigger in size. Male fish's rear end also have a smaller opening then females.
Males are usually more colorful then females and they act more rowdy then females.
The males are generally more attractive, and they have a long anal fin, as a female generally does not. The males are usually smaller than females, too. most of the time a gravid spot near the tail can be seen also.
it would depend on the kind of fish some fish Only the male have a certain color and in others fin size differs between the two
