This fish has to be one of the hardest to sex of any. My Petsmart has Bolivians too but they're all juveniles so it's impossible to sex them yet. BriDroid is right. The female has a thicker longer vent than the male and males have a small hump in the slope of their heads. It might just be too soon to tell on yours yet.
