Once the pregnant fish finishes giving birth to all the fish fry, you’d move the mother fish back into the main tank as it also eats its fry.
If your fish has already given birth in the main tank, you have to carefully take the fish fry from the main tank and put them into a breeding tank.
You can use a breeding net to scoop up the fry safely. Once you get the baby mollies, place them in a breeding tank and raise them until molly babies are old enough to be put back into the main tank.
