I have a baby platy that is about ------------- this big. Tonight I noticed her tummy is all bloated like she's pregnant. Please tell me that's not possible this soon. My baby can't be having babies!! ??? ???
Well, she certainly looks way too fat. But I couldn't see a gravid spot, and somehow she looked more bloated than preggy. Could she have somehow gotten WAY too much food, or possibly internal parasites that are causing bloating? Since she wasn't bloated I'd bet she overate to the extreme of that word. My Platys have done that a few times (kinda long story I don't feel like explaining at the moment) and that's pretty much what they looked like, just maybe not THAT bad.
Usually you can see a gravid spot on most livebearers, but sometimes their colour masks it. If its a baby platy I would think that she eats too much, as two of my baby swordies are female and are really fat and they're the only ones old enough to breed, the other babies in the tank are too young yet.
