Male or Female Black Skirt Tetras?

[aquariumboy]

I want to know if my black skirt tetras are male or female or at least how to tell a male from a female. Any help appreciated.

Those are all female. This is what a male looks like. Males are the ones with the "skirts"

Thank you for the information.

Umm, that is a long fin skirt tetra such as this. Males are actually larger then the females, and if you look in a pet store tank, they all look like that

To tell males and females, if you look from above, males should be more slender whereas females can have more of a round shape to them
