Yes, if it's a male, it will chase and try to nip the female. The males also develop small white spots on their gill covers. Another way to tell is by looking at it's anal opening.If it's a male, the vent does not stick out, it goes inward. The female's sticks out.

A male will have what resembles white pimples on the gills. There should also be a concave waste opening. A female's will stick out away from her body (convex).
