Usually the frontosas with nuchal humps are males. Also, males are generally bigger than the females. Another way to tell is, males are usually the ones that show aggression towards other males

This is FALSE sometimes. There are Some Big Females that Fight.
To tell if its male or female you have to vent them, Males have a small V shaped vent and Females have a O shaped vent.

Thats why I said "usually"
