General Information/Facts

    Poecilia sphenops is a species of fish, of the genus Poecilia, known under the common name Molly. They inhabit the coastal brackish and marine waters of Mexico.

    The common molly can produce fertile hybrids with many Poecilia species, most importantly the Sailfin Molly. In the case of black hybrids, they are called Midnight Molly. These are very popular due to their impressive dorsal fins, but require a bit more attention and have a somewhat decreased lifespan.

Diet/Food & Feeding Habits

    Plants/Algae, and other type green foods are absolutely necessary for good molly health. 


    Mollies are nice peaceful fish. Sometimes they will attempt to chase others around a bit, but do not hurt them in most instances. Mollies do best in a group with a few males and several females. Mollies are good tank mates for Swordtails, Platies, Angel Fish, Corydoras Catfish, Plecostomus..


    The males will have a pointed anal fin (gonopodium) and the females will have a rounded anal fin.


    Live-bearing aquarium fish, often simply called livebearers are fish that retain the eggs inside the body and give birth to live, free-swimming young.


    This species is the ancestor of the Black Molly, a melanistic breed which is black all over. It is one of the most well-known aquarium fishes and nearly as easy to keep and prolific as guppies (for optimal health and breeding success, they demand fresh vegetable food like algae). There are several other popular breeds, like the golden molly nicknamed "24 karat", or the balloon molly, which however has a deformed spine and a decreased lifespan due to the associated health problems. Also, breeds with altered dorsal fin structures like lyretails exist. The wild form is in fact quite rarely kept, as it has a rather plain silvery coloration suffused with brown and green hues. If given good care with ample sunlight, high water temperatures and fresh vegetables, they will, however, prove charming fish who make up for their somewhat plain coloration with their lively behavior.

    The salt tolerance of mollies allows them to live in water ranging from completely freshwater to completely marine, which makes mollies potentially compatible with a wide range of setups. This is fairly unusual, as most fish are compatible with only freshwater, brackish water or that of only saltwater environments. This ability allows mollies to live in a variety of coastal environments.
