Description
The twospot livebearer (Heterandria bimaculata) is a livebearing fish of the family Poeciliidae from Central America. The species has a stocky, olive to silvery body, often with a dark spot at the tail base, and reaches about 8 cm; it is thus larger than many related mosquitofish. It inhabits streams, rivers, springs and ponds with vegetation. As an omnivore it feeds on small invertebrates, insects and algae. Like other livebearers the species reproduces by internal fertilisation and bears live young; the male has an anal fin modified into a copulatory organ (gonopodium). It is hardy and is sometimes kept in the aquarium.
