-males have form of pointy anal fins
Females have got very rounded anal fins.Females have a little gonopodium.A gonopodium is absolutely a fish’s “parts”.Females have smaller ones.Females will also be much richer and a bit longer.
Gentlemen have directly anal fins.Males have a gonopodium, but any male’s is definitely twice the scale of this females.Gentlemen are a lot slimmer and smaller.
