The Dalmatian Molly is a hybrid color variation of Poecilia latipinna, the Sailfin Molly. The Dalmatian Molly has a black and white body, and is sometimes referred to as the Marbled Molly or Marbled Sailfin Molly. Mollies have the ability to adapt to a variety of salt levels in the aquarium. With a gradual acclimation, these fish may be maintained in either a freshwater aquarium or a saltwater aquarium. In the freshwater aquarium, a teaspoon of aquarium salt per gallon is recommended for optimum health.The Dalmatian Molly prefers a tank of at least 30 gallons, densely planted with plenty of strong plants such as Java fern, Sagittaria, Vallisneria and Anubias. They require a good filtration system because of their hearty appetites. The Dalmatian Molly is well suited for the community tank because of its peaceful nature, and is compatible with other peaceful, large fish that can withstand hard water. They may pursue their young and the young of the other fish.
