I bought 4 small Balloon Molly's just 2 days ago and I'm just wondering is my Dalmatian Molly pregnant or just fat? It's not possible that she could of mated while in the new tank as they are all females but she could of been pregnant when I purchased her. I really do hope not, I wouldn't know what to do! Even though fry are lovely little things my 12 gallon tank is just too small for them, thanks in advance. This is her by the way everyone.
