    How old do they have to be?
    My babies were born May 3 and the males and females are together in a tank. They are getting thier pretty colors and the males are already chasing the female babies around. Some of the females are quite fat with the black mark on thier tummys..does this mean they are pregnant at such a young age?

    You can start to breed babies guppys at 8 weeks old should seperate the males and females guppies when you can see which ones are the males and which ones are the females.

    The guppys are pregnant put they should be old enough to breed.
