Determining males and females

[EkizUCLA]

I just purchased a male platy from my fish store. I put him in the tank with my 1 female platy (I know shes female because she was pregnant when i purchased her). After looking at both fishs fins, I realized they are the same. Does anyone have any real good explanation of determining whether its a male or a female?

well if the fin is pointy and is pointing towards the end of the tail it is a male. but if the fin is round shaped(like a normal fin) it is a female.

At the bottom of the fish is a fin called the anal fin. In the males, the fin is pointed and rod-like. The female's fin is opened and shaped like a fan. It's very easy to tell males from females after you know what to look for. Hope this helps!

These are the females notice their anal fin which is triangle shaped

These are males notice their pointy anal fin

Hope you can tell the difference now!!!!!
