Males will have a longer top fin... specific name eludes me at the moment. Also they have a "fin" at the bottom more or less its just a hollow tube, they can move it around and generally poke the females with it.... Also females are just generally very fat due to having little mollies inside.... hope that helps some what.

A females anal fin is actually a fin,the males have the hollow tube and it folds back to the tail,so when you look at them if you don't see a true anal fin,it's most likely a male.
