Description

The merry widow is a livebearing toothcarp (Poeciliidae) from Central America. The species is small; the male is smaller and has a conspicuously long anal fin modified into a mating organ (gonopodium). Unlike egg-laying fishes the female gives birth to live young. It inhabits mainly stagnant waters, creeks and river shorelines over soft bottoms. As an omnivore it feeds on algae, detritus and small invertebrates. The species is harmless to humans.
