Description

The Catemaco molly is a livebearing toothcarp or molly (Poeciliidae) from fresh and brackish water of Lake Catemaco in Mexico. The species grows to about 8 cm and has a stocky, silver-grey body with a superior mouth to feed at the surface. 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 schools at the surface and eats algae, mosquito larvae and small invertebrates. The fish is harmless to humans.
