A tropical mix lake food is fine for your live-bearers. Feed your fish an amount which they can eat in a few minutes. Live food can also be part of the diet of live-bearers. This can come in the form of freeze dried food such as frozen bloodworms or shrimp. You should feed the adult fish twice a day, and should try to feed live food once a week.
Some people obtain live-bearers because they are the easiest fish to breed.
Pregnancy in females is easy to detect before feeding. Pregnant females have rounder bellies, and sometimes you can even see the silvery eyes of the fry before they are born. If this is the case, it is time to move the mother to a breeding tank. This can be a separate holding tank or another apparatus that can divide the current tank, separating the male from the female. Gestation lasts about four weeks.
