Pregnant Platy?

[reddawg1]

i have 3 platys(1 male 2 Female), due to their coloration all of them have large black spots behind the anal fins. is there any other way to tell when a female platy is pregnant

Typically, the black spots are the eyes of the fry. At first the stomach looks like it has little balls, for lack of a better word. Then the balls get bigger , then darker. As the eyes form, the stomach starts to look like it is getting black spots.

Your female platy will also eat the babies. My families platies had a few babies. Only the females were in the breeder and only four babies survived.
