Pregnant black mollies giving birth is known as “free-spawning,” meaning that the pregnant female molly will release her eggs into the water column, and the male molly will fertilize them.

2. Egg Laying Stage: The female will lay her eggs on a flat surface, often in clumps or “strings.” Depending on how many eggs she produces, there can be anywhere from 2 to 500 strings per spawn!
3. Developmental Stage: Once the embryo has been fertilized, it begins developing into a fry. During this stage, the fry will feed off of the yolk sack inside the egg until they are ready to hatch.

At this point, separating them from their parents is essential, so they don’t get eaten.
