Hi

I have 5 head and tail light tetra's in my tank with other fish. But i was wondering how you can tell which is male and which is female.... . 2 of mine are more rounded with a short tail and 3 are slim with a long tail. Hope someone will be able to help me thanks sue

I'm not sure you can, though it doesn't really matter unless you are going to breed them?
