Platy is livebearer and easily breeds in community tank. The breeding tank should be 10 to 20 gallons in size with gentle filtration and dense vegetation. More than one female should be kept with each male to reduce the stress on females from harassment by the male in aquarium. The young platy reaches sexual maturity at four months of age and they can quickly overpopulate an aquarium. Female becomes pregnant when she develops a gravid spot on her abdomen. The gestation period is about 24 to 30 days. Mature female platys give birth once every 4-6 weeks and each brood contains up to 80 fry. The fry accept brine shrimp nauplii or powdered flake and grow very quickly if it is fed 2-3 times a day.
It is easy to make difference between the male and female. The female is generally larger with less vibrantly colored than the male. Females have a fan-shaped anal fin, wide bellies with a dark gravid spot while males have a rod-like structure in anal fin which is known as gonopodium. Males also have a more pointed caudal fin.
