If you are troubled with this question, your troubles are already over. It is not difficult to differentiate between the two sexes of the Mollies species of fish. You can tell the difference between the colors, body shape, fin shape, and size.
Size and shape of fins
Fins are probably the first thing you want to observe if you want to tell the difference. The males possess anal fins that tend to point backward. They also have larger fins. Whereas in the case of females, the fins are smaller in size. The anal is also of a different shape than that of the males.

You can tell the difference from the shape of the body as well. The females have a bigger abdomen than the males. While the males tend to have a slimmer body than the females. The females also have a larger body than the males while they are pregnant.

Breeding Mollies is just as easy as telling the difference between the male and the female. So if you are thinking of breeding fish species, mollies are the ones you should go for. It is easy for beginners as well.
To breed Mollies in an aquarium, you will have to set up a breeding tank. Get a tank of about 5 gallons and set it up to 78℉. Then select a male and a female from your group of mollies and place them in the breeding tank.
As the interest in mating rises, the male will begin to show certain behaviors to attract the female. If the female doesn’t show any interest for about two days, you should swap the male with another male.
As the female shows interest in the male, the male will fertilize the eggs by transferring the sperm to the female’s body. They do this through the anal fin known as a gonopodium. Then comes the turn of patience, you will have to wait for the female to give birth.
As the female nears giving birth, she will remain in a secluded or dark area of the tank. This usually takes about 45 days, and the female can give birth to about 100 fish fries.
As soon as the female gives birth, return the parents to the main tank. Mollies tend to eat their babies, so removing them is a necessity. Then you can give the Molly babies powdered fish flakes.
