I don't know if they are sexually dimorphic at the 1 in.-1.5 in. size usually seen at the fish store. My impression from some of the reading I've done in the fish breeding forum is that fully grown the male is a good bit larger than the female.

This is my gramma that I believe is male because it is the largest I have seen. (He) is a solid 3 inches long and at least as thick in diameter as my index finger. The picture is two to three years old.
