HI guys/gals. How do I tell if my balloon molly is pregnant. All my other females have never showed a gravid spot, and yet some have had fry, so I have no idea what the gravid spot looks like. As she has a huuuuge belly as it is, I have no idea how to tell. She hasn't been hovering around alone in the gravel or anything, but not all of them do that anyway, especially not throughout the whole 'pregnancy'. I'd like to think that she's getting bigger, but it could be my imagination. Any tips?
