I've noticed that my one of my male balloon mollies (who recently lost his female) frequently chases after the other male in the tank (a non-breeding male who refuses to breed for some mysterious reason). I was wondering if this aggresstion is becuase there aren't any female mollies in the tank for him?
I'm going to get a couple females for him, but my non-breeding male is so starnge! I had two females in with him and he just swam with them . . . acting like he wasn't a male at all! His gonopodium isn't straight; it's angeled upward and looks a bit different compared to the other balloon molly. Maybe he was a female before and developed into a male before I got him. Anyway, thanks for the advice!
