How long does it take for a molly to give birth?
After an average of 30 to 40-day pregnancy, it will take a molly approximately a day to give birth to her fry. Many mollies can actually store sperms for months at a time, fertilizing their eggs themselves every 30 days. They can birth anywhere between 20 and 100 fry at a time.

How many fish do mollies give birth to?
Gestation and Birth
They can give birth to between 40 and 100 fry. Mollies that are young or are having one of their first few pregnancies will tend to give birth to a smaller rather than larger number of fry. When a molly female is near her time to give birth, you will need to separate her from the rest of the tank.

How many eggs do molly typically lay? None. They’re live-bearers, which means live birth. Anywhere from a few to over a hundred could be born.
Why is my molly staying at the bottom of the tank?
When the swim bladder malfunctions, the fish has trouble maintaining his level in the water and can sink to the bottom of the tank or be stuck near the top. The abnormal ballast can cause the fish to turn sidewise and swim on his side, or even roll entirely upside down.
What do I do with my pregnant molly fish?
One way to keep the fry safe is to use a breeding box – a container that goes inside the breeding tank. Place the pregnant fish into the box and allow her to give birth. The resulting fry can safely slip through the small openings in the box into the larger part of the tank.
