Sexing my fish

[Anna94]

Can do I sex my cardinal tetras, oto, lemon tetras, and GloFish tetras (don't have the GloFish or lemon tetras yet, but want to know for when I do get them).

What are their genders? These are the best pictures I could get.

Hard to say Generally that theory is that the female cardinal tetras are larger than the males

How will you breed them?

I don't plan on breeding. I just wanted to know their genders so I can give gender appropriate names, lol. I figured it out, though and they are all named.
