Dalmatian Lyretail Molly (Poecilia latipinna)

dalmatian lyretail molly

The dalmatian lyretail molly, also known as the spotted molly, dalmation molly, or Poecilia latipinna, is a species of live-bearing fish belonging to the Poeciliidae family of mollies, along with guppies and swordtails.

This species may be either an annual or a short-lived perennial, depending on factors such as temperature, food availability and predation pressure in its native range. The dalmatian lyretail molly grows quickly to sexual maturity, reproduces year-round in captivity and has a low survival rate once sexually mature.

This species of fish is closely related to the sailfin molly (Poecilia Poecilia latipinna) and the Mexican tetra (Poecilia mexicana). Similar to other members of the livebearing species, this fish can produce up to 1000 offspring in one litter after only 5 to 6 months of pregnancy.

The Dalmatian Lyretail Molly are small live-bearing fish that come in many different colors such as black, gold, red, orange and white, but the most common color is black with bright yellow spots.

Origin and description

The dalmatian lyretail mollies are from Mexico and Central America where they live in slow-moving streams with lots of vegetation and are usually found in water about two feet (60 cm) deep or less.

This hybrid color variation of the Sailfin Molly, Poecilia latipinna, is called Dalmatian Lyretail Molly. It can sometimes be called the Marbled Molly or Marbled Sailfin Molly because of its black and white body and slightly lyre-shaped caudal fin.

There are several salt levels in aquariums that Mollies can adapt to depending on their environment. A saltwater aquarium or a freshwater aquarium can be maintained for these fish with gradual acclimation. For optimum health, add a teaspoon of aquarium salt per gallon to freshwater aquariums.

Breeding

Mollies are livebearers, meaning that babies come out of the mother alive. The breeding of Dalmation mollies occurs easily, and the pregnancy lasts between 20 to 40 days.
A female molly can give birth to a baby molly for up to five months without a male. It’s because their abdomens are usually filled with fertile eggs. There are usually 20 to 100 babies born at once.

It is recommended that the breeding tank have at least two to three females per male, 79°F water temperature, and a large number of floating plants for this species to breed in captivity. Their gestation period is around two months, and they are livebearers.

When you feed Dalmatian mollies with premium fish food flakes and keep the water conditions right, breeding occurs very easily. A female fish can keep sperm in her body for up to 5 months and give birth to molly babies more than once when she mates with a male fish.

Are they aggressive or peaceful?

Mollies are not aggressive fish and can make good tank mates with most other peaceful fish. They are not overly territorial, so they will usually get along with other mollies in the same tank.

Male mollies will sometimes chase each other around the aquarium. While this doesn’t harm the males, it can be quite annoying to see them circling all day long and can lead to tails being bitten off or fins getting torn.

You will also need an efficient filter that produces lots of current and some plants for the fish to graze on. In addition, this breed has been known to produce litters in excess of 100 fry, so you’ll want to provide plenty of room for swimming and vegetation.

The Dalmatian Lyretail Molly should not be kept in anything smaller than a 30 gallon tank due to their large litters. The Dalmatian Lyretail Molly prefers heavily planted tanks but may accept other types of tank décor if it has enough space.
