Ok since I still have no idea if my molly is a girl or a boy, (I looked at the sexing livebearer page , but my molly seems to sometimes have the dorsal fin or a boy and girl, unless the boys dorsal is supposed to be just a straight pointy fin, and doesn't fan out even a little bit..then I know I have a girl) Anyways I don't want another molly. Only because problem is if I get a boy molly and mines a girl molly, they might have babies, and I don't want that. Or if I get a girl molly, and ithe others a boy same perdicament. So I was wondering if to have only one platy and one molly would be ok..they'de keep eachother company and get along good. Though I would really just like another molly.
