Description

The San Jeronimo livebearer is a small livebearing fish of the family Poeciliidae from southern Mexico. The species reaches only about 5 cm and has a streamlined, olive to silvery-grey body with fine dark cross-bars. It prefers fast-flowing waters. Like other livebearers fertilisation is internal and the female gives birth to fully developed young; the male has an anal fin modified into a copulatory organ (gonopodium). The diet consists of algae, detritus and small invertebrates. Because of its small size the species has no fishery value.
