The Dalmatian Lyretail Molly is a hybrid color variation of Poecilia latipinna, the Sailfin Molly. The Dalmatian Molly has a black and white body, with a somewhat lyre-shaped caudal fin 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 Lyretail 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 Lyretail 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.

The pointed anal fin and much larger dorsal fin on the male, and the rounded anal fin and pregnancy spot on the female differentiate the two. The Dalmatian Lyretail Molly is a livebearer that requires a spawning box in a large 25 gallon, or larger breeding tank. The aquarium should be planted as densely as possible or have a thick algae mat. Having a group of floating plants in the corner of the aquarium will promote rearing outside of the breeding tank. Every 60-70 days the female will give birth to 10-60 young that are already approximately one-half inch long.

The Dalmatian is omnivorous and requires algae. Provide these fish with an algae-based flake food, as well as freeze-dried bloodworms, tubifex, and brine shrimp.
