(Other members of the genus Poecilia)

ADULT SIZE: 10 cm

WATER CONDITIONS: Not critical

TEMPERATURE RANGE: 18-28 C

FOOD: Feed Poecilia sphenops anything, a true omnivore. Although they will eat most foods, and readily accept flake, they do require a vegetable component to their diet; leave some algae in their tank on which they can graze.

DISTRIBUTION: This species comes from Belize, Guyana, Mexico

AQUARIUM CARE: The Molly, like other members of the Poecilia genus, are well known in aquarist circles, with very many colour strains available. They are not as easily maintained as some other livebearers, and although widely available, should perhaps be avoided by the new aquarist.

Their natural habitat is in fresh and sometimes brackish waters in Central America; adding a small amount of salt to their tank is possible, but certainly not necessary.

They are a very hardy species, perhaps a little more aggressive than similar species such as the Platy, but in general make great community tank subjects.

BREEDING: Mollies, like other widely available livebearers, are very easily bred, with tens or hundreds of fry produced every few weeks. Adults will eat fry, and although some will always survive, adults (or fry) can be removed to increase survival rates.

Fishkeeping Facts and Tips

Avoid tankbusters! Too many tropical fish stores sell small fish that will continue growing until too big for any home aquarium. Rehousing can be very difficult indeed. Avoid species such as the shovel-nosed and red tailed catfish
