I think I may have a prego black molly fish. I just got three of them a few days ago, and Mark says "oh, my brother used to keep those fish, and THAT one is preggo!" She is not a "balloon molly" before you ask..
So has anyone ever bre these? I had an extra 10-g tank (sadly my puffer fish bit the dust.) So I put her and two others in there.. not sure 100% on their sexes but I am Googling that now.
