Velvet black has always been considered the classic color variant for the mollies. Nevertheless, breeders always try to create something new and unusual when creating new breeds.

White mollies are born this way. White Sailfin Mollies (Poecilia latipinna) and Giant Sailfin Mollies (Poecilia velifera) are collectively known as the white Sailfin Molly, along with several hybrids. There is no such thing as an albino molly.

Unlike their congeners, white mollies differ only in their body color. As with other decorative species, these are all unpretentious fish that get along well with other decorators.

Viviparous Mollie fish develop their eggs in the womb of the female, and the fry is born already fully developed and ready for independent feeding.

Beginner aquarists can breed their fish with ease due to this feature. Additionally, breeding is a simple process that lets everyone become a breeder and have a chance to get a different color form of fish.

A white molly has an elongated and laterally compressed body. Their heads are thin, and their mouths are upper. Black eyes stand out against the white body, which contrasts with the large and round size of the eyes.

Depending on the species, the dorsal fin can be small or well developed. The only differences are its transparency and white spots. In general, the caudal fin resembles a lyre. The female Molly can grow up to 10 cm in length, while the males are much smaller.

White mollies exhibit considerable sexual dimorphism, the anal fin of males transforming into a tubular organ called a gonopodium, while the anal fin of females remains triangular.


The white molly is a result of breeding, so it is not found in the wild. The species is endemic to Central America.

Additionally, fresh and slightly salty water are beneficial to fish, as are areas where rivers flow into the ocean (where rivers flow into the ocean). Mollies naturally occur in a wide range of salinities and can withstand very slight increases in salinity.

White mollies are commonly found in home aquariums all over the world. You can find them from special aquarium farms or local aquarium breeders.

A proper water tank needs to have 20% of the water replaced once a week. When you want to make tap water safe for mollies, you should add Tetra AquaSafe conditioner to it. It is designed to instantly remove chlorine compounds and heavy metals from the water, making it suitable for them.

Aquarium water parameters should be between 23 and 28 degrees Celsius, a pH of 7.0 to 8.0, and a GH of 10 to 20.

White mollies can withstand a little rise in salt (up to 2-3 g/liter of water). However, keep in mind that this should not be done in shared aquariums since not all species will be able to resist it.

Such suggestions are common, but they are not required because white mollies thrive in freshwater.

Tank Mates

Among the best candidates for a general aquarium are white molly fish because they are peaceful and friendly.

White mollies are recommended to be kept with other fish such as Swordtails, Odessa Barbs, Tiger Barbs, Denison Barbs, Tetras, Rainbowfish, Harlequin Rasboras, and peaceful catfish, including Hypostomus and Corydoras. If you keep your white mollies with large predatory fish like an Oscar, Flowerhorn, or Parrot Cichlid, they can become stressed.

Presented as omnivorous fish, white mollies should consume both plant and animal food. Mollies readily accept any type of food, whether it is live, frozen, or natural.

The disadvantages of these fish are many, including their imbalance, ability to carry infections, etc. Water quality can also quickly degrade when they are present.

As a result, it is recommended to stick to high-quality dry food. These products are rich in vitamins and nutrients and contain a wide range of nutrients.

Since the components are easily digestible, fish waste is less likely to pollute the aquarium. White mollies should be fed twice a day with a tiny bit of the feed and ensure that the fish entirely consume it within a few minutes.

It is also suggested that mollies have a fasting day once a week. They can be helpful on days like these by eating up some algae development in the tank.


The offspring of mollies can easily be bred at home. They are viviparous, meaning they do not require specific conditions in order to reproduce.

Small fry will soon appear among small-leaved plants, soil, and decorations if you have a few fish.

You can differentiate the male and female white mollies quite easily. You can tell the difference by looking at the anal fins. A tube-shaped fin (gonopodia) is a male, while a standard-shaped fin (fin) is a female.

Molly whites reach sexual maturity at around a year of age, and females a little earlier. Using the gonopodium, he inserts the sexual products directly into the abdominal cavity of the female after chasing her for some time.

Females at the point of childbirth should be transferred to a special jig or spawning aquarium. The fry has a greater chance of survival because, in a typical aquarium, neighbors and even the mother can consume the fry.


Fried eggs are apparent as soon as the abdomen swells, the anal fin darkens (not so noticeable on black species), the annulus swells, and the females frequently lie alone in dense vegetation.

A fascinating fact is that male reproductive products can be stored in the female’s body for a long time, gradually fertilizing the eggs. This means that spawning can occur even if only one fish is present in the aquarium.

It usually takes about one month for eggs to develop in a female’s body. Water temperature plays a role in how quickly eggs incubate.

White mollies are fertile – they can produce 50 to 350 fry per female. When they are born, the fry can feed themselves immediately. TetraMin Baby fry feed is an excellent choice for feeding them.
