Mollies

Mollies are members of the Poeciliidae family and are widely distributed from the southern United States to South America. Mollies are very versatile fish having the unique ability to live in both freshwater and saltwater if acclimated slowly. Some saltwater aquarists use mollies to establish a new marine aquarium. Mollies are tolerant of a variety of water conditions, but prefer some aquarium salt in the water for optimum health. Ideally at least a tablespoon of aquarium salt per gallon minimum is recommended. Through selective breeding programs, Sailfin, Balloon, and Lyertail varieties are available. Most mollies grow slightly larger than other livebearers, so it is best to provide these fish with an aquarium of at least 30 gallons, with plenty of hiding spaces. Just like other livebearers, mollies are easy to breed, and make fascinating fish for the seasoned aquarist. These fish will add drama and contrast to the semi-aggressive aquarium.
