Description

The oblique livebearer is a livebearing toothcarp (Poeciliidae) from fresh water of Central America. The species grows to about 6 cm and has a stocky, silver-brown body with an oblique dark band or row of spots on the flank. The male fertilises the female internally with an anal fin modified into a gonopodium, after which live young are born. As a social fish it swims in streams and pools and eats mosquito larvae, small invertebrates and algae. The fish is harmless to humans.
