Description

The toothy girardinus is a small livebearer of the family Poeciliidae, endemic to Cuba. The species is small and has a slender body; like all poeciliids the female bears live young and the male has an anal fin modified into a gonopodium for internal fertilisation. It inhabits ponds, lakes and streams but prefers clear, sluggish streams. On the bottom it feeds on aquatic vegetation, diatoms, algae and insect larvae. The species is harmless to humans.
