sexual differences in golden nuggets
I'm just curious to know if there are any sexual differences since I've read that they can be territorial so you can't really keep them in groups if your attempting to breed them. Anyone know of any sexual differences?

From the Vires book:
"Dimorphism is difficult to notice unless the fish are at full breeding size. Probably the easiest way to sex these fishes is by the shape of their foreheads. Males have a flatter, more leveled slope to their foreheads and are slightly wider. Females have a more rounded forehead and are slightly plumper when in spawning condition. There is no noticeable difference in odontodal growth in either species."
