Tetra's M or F question!

Ashy

How do you tell if a tetra is a male or female? I've got two long skirt Tetra's and one Buenos Aires.

Thanks in advance!!!

If there are external differences, they will be mentioned in our profile of the species. Click shaded names, Black Widow Tetra [aka Black Skirt, the White is the same species] and Buenos Aires Tetra. [If the name as it appears in the profile is used identically in posts, it will shade.]

I've got skirts, and the males are much skinnier than the females. The area from their faces to their bottom fins are more of a quarter circle shape in females, where as males are parallel to the arch at the top of their bodies.
