Poecilia

Poecilia is a genus of fishes in the family Poeciliidae of the order Cyprinodontiformes.[1] They are native to fresh, brackish and salt water in the Americas, and some species in the genus are euryhaline. They are often seen as live-bearing aquarium fish. All species in Poecilia are called mollies except for the Endler's livebearer (P. wingei) and the well-known guppy (P. reticulata). Without a modifying adjective, molly usually refers to the species Poecilia sphenops.

Micropoecilia has been proposed to be included as a subgenus of Poecilia.[2]

Aquaria[edit]

Along with their platy relatives, the mollies are part of a pivotal aquaculture group of livebearers, which can live in water from fresh to fully marine, and a wide range of other conditions. They feed on smaller insects, animals, and vegetation.

IUCN lists two of the species, the sulphur molly, P. sulphuraria, and the broadspotted molly, P. latipunctata, as Critically Endangered.

The generic name Poecilia derives from the Greek ποικίλος (variegated), in reference to the fishes' coloration. Mollies need to live in water at 25 to 28 °C (77 to 82 °F).

Mollies occur in several different colors and spot patterns, such as black, white, black and white spots, orange, and orange and white spots.

Mollies have been kept successfully in freshwater, brackish, and saltwater conditions, although the last is not recommended for the novice aquarist.
