There bellies get very big and rounder and drop, swim slower and properly eat alot more. Don't forget to add a variety diet i.e mixture of flake and live food, try getting some freeze dried Brine Shrimp, Blood Worms etc. As they safe to use and wont introduce diseases into your tank. Also add some bushy plants to your tank so that the babies have somewhere to hide when they are born usually takes 28 days after mating with the female. Do you now how to identify a male from a female?
