Molly
The
Molly (
Poecilia latipinna) is a popular
freshwater aquarium fish species. It is a member of the
Poecilidae family and is therefore
live-bearing. It prefers
hard water and can withstand a surprising degree of
salinity. Indeed, mollies can be habituated to full-strength sea-water and live in a marine
aquarium if need be. Mollies are more herbivorous than most aquarium fish and have a tendency to consume aquarium plants.
The species originates in the coastal areas of central America, on the Caribbean costline.
