If it is a girl then it will have a bigger stomache than a boy but if it is a male the stomache is smaller.

Honestly, your photo is not clear enough to make it easy to tell.

The only reliable way to sex livebearers is to look at their anal fins. Just looking at the stomachs is not all reliable since some females stay slender right up until giving birth, some males eat a lot and always look pregnant, and sometimes a large stomach in either gender can be either constipation or disease.

Look closely at the circled areas in this picture. Females have a normal anal fin (she's first in this picture), males have an elongated, stiff, almost spiney looking anal fin that they can never open normally like the females. Now, females will clamp their anal fins from time to time and can look briefly like a male's anal fin, but then they can open them again normally. The male's stays stiff and folded all the time.
