Description

The sailfin molly is a livebearing toothcarp of the family Poeciliidae reaching about 15 cm. The silvery-grey body is covered with rows of spots that sometimes merge into streaks; the male stands out for its large, sail-shaped dorsal fin, which he raises in courtship to impress females, and bears a rod-shaped mating organ (gonopodium). The species lives in fresh and brackish water of the southeastern United States and Mexico, along quiet, vegetated margins, ditches and estuaries. As an omnivore it eats mainly algae and growth, supplemented with midge larvae and plankton. Unlike most fish it is a livebearer: after internal fertilisation the female gives birth to live young. It is a popular aquarium fish.
