The Barred livebearer (Heterandria jonesii) is a freshwater fish of the family Poeciliidae that grows up to 7 cm.
Description
Heterandria jonesii is a small livebearing freshwater fish of the family Poeciliidae from eastern Mexico. The species reaches only a few centimetres and has a stocky, streamlined body, often with a row of dark spots or bars on the flank. It inhabits vegetated streams, springs and slow-flowing waters. Like other mosquitofish the species reproduces by internal fertilisation and bears live young; the male has an anal fin modified into a copulatory organ (gonopodium). The diet consists of small invertebrates and aufwuchs. Owing to its small size the species has no fishery value.
