Breedinglivebearers. 

This term (livebearers) means that their fry come out swimming and "ready" to the big World. 

The gestation period for this fish is usually 28 days but sometimes can take some more time.

Like all livebearers when the female is in pregnant it will develop a dark  triangular shaped gravid spot

near her anal vent.

As the pregnancy progresses this dark  triangular shaped gravid spot will get larger and darker.

At the time the fry comes out recommended to move them or the parent to another tank or

else the parent will eat their own fry.
