Males are often slimmer and smaller in size.:) That's all you needed to know when distinguishing the sexes of both of your tetras.:)

Sent from my desktop or phone or whatever else I am holding on to  2
I'm ready for the pressure.
The drama and the pleasure!
If there is one thing I want to see here, it's HUMOR.
I believe I can fly!
I believe I can touch the sky!
I think about it every night and day!
I stand in awe of my body.

Females are deeper in the body.

Another couple things you can look for, most tetras, the male's anal fin has a slight hook to it. Also, on glo-lights in any case, the males sometimes get a white stripe on the leading edge of their dorsal and anal fins (really quite striking. Perhaps my favorite thing about these fish.)

Logic is only the beginning of wisdom
