Sex my fishies

[Chilli]

How can I tell what sex my fish are?


I have mollies

The males will have a gonopodium, an elongated thin fin near the anal opening go to the livebearer forum for better help. I have some Swordtails that are not too different from mollies. The females have a larger anal fin. Welcome to the forums.

Hi Chilli

Welcome to TFF.

I'll move your thread to the Livebearers forum where I'm sure you'll find good advice about all aspects of keeping your mollies.

On their underside of their bodies, male mollies have a pointed fin and female mollies have a fan shaped fin.
