History of appearance
Thanks to the efforts of German aquarist Bill Sternke, the artificially bred species known as Black Molly or Black Molly came into existence. He worked on producing a velvety-shiny, completely black molly for nearly 11 years. Only in 1948 were these mollies introduced to Russia, and they became very well-liked.
Experts continue to disagree on the Black Molly’s origin. While some contend that Poecilia sphenops genes were used in the breeding process, others assert that Poecilia latipinna was the ancestor of this species.
The black molly has inherited exceptional health and endurance from its wild ancestors, despite the continuous debate regarding its origins. This fish is a great option for beginners as it is easy to care for, gets along well in a home aquarium, and requires little maintenance.
Characteristics
Black mollies come in two varieties: classic and balloon.
The following traits define the classic molly:
- Body – dense, elongated. The size of an adult varies from 7 to 10 cm. Large rounded eyes are located on the head, as well as an upper mouth.
- Fins – the tail has a rounded shape. All fins are small in size and black.
- Color – rich black with a velvety sheen, the scales do not shine or shimmer. At first glance, the fish seems matte.
Molly the balloon is the exact same color. Its name, however, comes from its shorter body and prominent abdomen. The balloon molly has a lyre-shaped tail that is longer.
Differences between male and female
Black molly males are consistently smaller than females. Males also have gonopodiums in place of anal fins. This fin has been altered with the purpose of fertilizing the female.
There are occasionally black mollies in aquariums with specks of other colors. Although these fish have a peculiar appearance, breeders consider them to be flawed, and they frequently discard or forbid breeding them.
The content of Black Mollinias is quite unpretentious.
Ideal ratio is two or three females to one male. By doing this, group disputes will be avoided.
Aquarium, soil
A single mollinism ought to accommodate a minimum of 10 liters of volume. It is advisable to prioritize rectangular models. You must make sure a lid is present beforehand because these fish are playful and highly active, capable of leaping out of the water.
Soil is either medium-sized sand or pebbles. Each color is chosen separately. The ground does not have any particular requirements. However, confirm that its composition does not contain any sharp particles that could harm fish.
Decorations, plants
Mollies often nibble on aquatic vegetation.
Consequently, species with robust and dense foliage are preferred, such as:
It is ideal to plant plants around the aquarium’s periphery, making sure to leave room for expansion in the middle.
Driftwood and organic rocks can be utilized as décor. Pet stores also sell grottoes and themed decorations.
Lighting, aeration, filtration
Black mollies don’t require much lighting. They are able to survive in both bright light and daylight. For this reason, lighting is usually chosen with the needs of the plants in mind.
You need to use a filter and an aerator. The equipment’s power needs to match the aquarium’s dimensions and volume. You can use filter and aerator combination models for convenience. To keep an eye on the water’s temperature, a thermometer must also be purchased.
In an aquarium containing mollies, some aquarists recommend adding salt to the water. But there’s no need for this. However, black mollies can easily survive in water with a salt concentration of 2-3 g/l if that is their preference.
Care
It is necessary to clean up occasionally, just like with any other fish in an aquarium with mollies.
It is required to change up to 25–30% of the aquarium’s water once a week.
Feeding and diet
In terms of food, black mollies are unassuming. They consume food derived from animals as well as pre-made food mixtures with joy.
Ready-made industrial feeds with a balanced composition and added vitamins and minerals can serve as the foundation of a mollie’s diet. Flakes and light granules that are able to remain on the surface for extended periods of time are the ideal solution.
Given that these fish are omnivores, they should eat both plant-based foods and proteins.
Give them plant food, such as lettuce leaves, fruits, and vegetables, several times a week. If there isn’t enough plant food, mollies will gladly gorge on aquatic plants.
Mollies require feeding one or two times a day, such as in the morning and evening or just during the day. Each person chooses the portion size on their own. It’s critical that the fish have five minutes to consume their norm. You are probably feeding too much food if the leftovers sink to the bottom and stay there for a long period.
Fish that are particularly gregarious and prone to obesity are black mollies. For this reason, they observe a fasting day once a week. Additionally, it is strictly prohibited to feed Mollies only protein-based foods, as this will eventually result in the development of gastrointestinal tract pathologies.
Breeding: conditions, stimulation, features
Mollies are good home breeders. Prior to producing offspring, healthy and sexually mature producers must be chosen. When black mollies reach 8 to 12 months of age, they are ready to breed. Fish that mate can do so in separate aquariums as well as shared ones.
For two producers, a 10–20 liter aquarium works well as a spawning tank. It is necessary to have an aeration system and a small filter. Installing a thermometer to keep an eye on the temperature is also the best option. Ensure the mark doesn’t rise higher than +28 degrees.
Instead of laying eggs, the female molly gives birth to fry that are fully prepared for an independent life. Every 30 to 40 days, the fish can "give birth," producing up to 300 fry at a time. The female must then be put back into a shared aquarium. The fry are fed with specialized feed mixtures. Feed little amounts five to six times a day on average. Additionally, it’s critical to keep an eye on the aquarium’s water quality and promptly sort the developing mollies.
If spawning takes place in a shared aquarium, it’s important to make sure the fry have plenty of places to hide. If not, they might experience dental problems from both their parents and their neighbors. If desired, you can separate the pregnant female and her offspring from other fish by using specialized breeding tanks.
Each new batch of eggs is fertilized by the male’s seminal fluid, which can stay inside the female’s body for an extended period of time. Therefore, even in the event that the father of the progeny is not present, any female molly who has coexisted with males in the same aquarium has the potential to give birth to fry more than once in the future.
Subspecies
Black mollies are classified into two subspecies:
Possesses short fins and an elongated, proportionate body. Is the most prevalent kind
Is characterized by a large belly and a shortened body. Fin lengths range from short to long. People who have a caudal fin shaped like a lyre appear extremely stunning and unique.
