Is my Balloon Molly Pregnant?

[vandrez]

Hey Guys...

I only just bought a pair of balloon mollies and the shopkeeper says they are both female. However the black one is rounder than the orange one.
I think she is pregnant and have kept the mollies away from the other fish in a seperate tank.

The orange molly always seem to be sniffing the black ones rear. Anyway am posting some pics of the black one.
Do let me know if she is pregnant and if she is, then should she be kept all alone untill the fry is ready?

Thanks

Im not sure if your molly is pregnant (I'd say yes but im not 100%) but if your other one is sniffing the other mollies rear then its possible that you have a male there. If his anal fin looks similar to this then you do >>

Notice the fin in the second photo? If your orange one looks like that then you have a male.
