To tell the sex you have to look at the analfins. Females will have a fin and the male willl have a godonum( is like a horizontal fin) To tell if they are prego look by the analfin and if you see a gravid spot(black area) above where they poop then they are prego

How to identify if you fish is male or female

Livebearers such as: Mollies, Platies, Swordtails, Guppy and Endlers are quite easy to sex when you know what to look for.

When looking to sex your fish you need to look for the gonopodium. This is the analfin on males. This fin is next to the belly of the fish.

A female’s analfin will be rounded and will look like this:
