Any platy experts?

[NinkyNonkyNinkyNonk]

My platy Mickey Mouse fish has looked very round for around four weeks now. Anyone know whether she's pregnant or just fat?

Or perhaps even if my she, is a she? I am obviously no fish expert, only got them a few months ago, but "she's" definitely getting big one way or another.

Thanks!

Definitely a she and her bottom fin is curved. She is most likely pregnant as they are prolific breeders. She will most likely eat the babies herself or other tank-mates will so you have some degree of population control
