Content, care and feeding

Mollies, like other viviparous fishes, are very hardy, not complicated in maintenance, unpretentious to the stern. Mollinesia has a dense short body with a strong fin and a bright belly. Females are much larger than males: the body size of males is ten centimeters, females - sixteen centimeters. Yellow-gray color - is the main body tone of individuals, with scattered on it spots of green, blue, black and yellow colors. The sex of individuals is established in the form of a fin - in females it is rounded, in males it is rolled up into a tube, forming genopodia, which is their common organ. Life expectancy of Mollies is five years.

Black Molly requires a volume of water from 60 for normal development and vital activity, and ideally from 100 liters.

Popular types of MOLLINESIA

Here are the most popular types of mollies: black mollies (lira-molly), Velifer mollies, sailing mollies, sailing mollies. Silver mollies (also called snowflake mollies) is a selection form of sailing mollies.

Keep them better in groups or in pairs.

This fish lives mainly in the upper and middle layer of water, loves the water space and light.

The light day of mollies should be at least 12-13 hours. It is useful for fish, if at least a couple of hours a day lighting is natural, but if there is no possibility, then you can do without it.

Of course, she also needs natural shelters: thickets of plants, snags, decorative ornaments that can serve as a refuge.

Mollies feed on all types of dry and live food.

The only condition that helps to maintain the activity and health of these fish is that they definitely need plant fiber.

Therefore, along with others, use vegetarian feed, plant in the aquarium plants with soft leaves, which the fish can eat. You can also feed them in small portions of chopped boiled vegetables.

Another important point in the content of mollies: at home, they live where the river water mixes with the sea water, and therefore they like hard water. If you only have mollies and placilia in your indoor pond, you can even add some salt to the water on purpose. If other fish also live with them, then of course you should not do this. But in the case of illness or quarantine, the fish can be deposited in an aquarium with salted water - so it will come back to normal faster.

Breeding Mollies

Mollies are viviparous fish that become sexually mature between the ages of five and twelve months. When the female collects her calf in her belly, the male inserts her gonopodia into her anus and releases the sperm. The process of fertilization of eggs takes place inside the female. The frequency of sweeping is from twenty-eight to fifty days, and the gestation period is from ten to sixty days. The number of fry born depends on the age of the female specimen. Mollies fry develop very quickly, as they are born in fairly large individuals that need to be provided with good nutrition.

Fry mollies

At one time, the female gives offspring to 50-60 rather large fry. You should know that molly fry are very vulnerable to water pollution, therefore in the aquarium with fry it is recommended to replace part of the water more often than usual. To enhance the immune properties of fry, you can add some salt water. Primary feed: Artemia and Cyclops nauplius, live dust, crushed, high-quality artificial feed.

Gender differences:

The male is smaller than the female, more colorful and possesses gonopody. For mollies characteristic feature in the form of a sex change. Depending on the conditions of detention, they can change their gender. Moreover, it can happen at any age.


The name "molliesia" originated from the genus name - Mollienesia. The natural range of these fish is fresh and slightly saline waters of Central America. Wide mop mollies live mainly in reservoirs with standing waters or small currents in southeastern North America. The natural color of these fish is very colorful, mostly dominated by yellow-gray and spotted species.

For the first time these fish appeared in Europe more than 150 years ago, it was the spotted mollies that became the favorites of aquarists. Then, the popularity of the hybrid form, which acquired the name black mollies, gained popularity. Black mollies were obtained as a result of breeding in the United States, and in the early forties of the last century they were bred in the territory of the Soviet Union.

In the sixties, it became fashionable to keep other mollies - the lira mollies. Which, in turn, were also bred by selection, as well as fish with a short disk-like body.

At first glance, domesticated mollies resemble swordtails. But mollies have wider tail fins and more dorsal fins. The females of these fish are slightly larger than the males. With good care and favorable conditions, females grow up to 8 cm, and males up to 6 cm. Wild representatives of this species are one and a half times larger. In addition, the fish living in the wild have a somewhat oblong and more rounded body, they are somewhat reminiscent of the placium.

Even an inexperienced eye can distinguish females and males; the males have a long process at the anal fin - gonopodiums.


Mollies are viviparous fishes, they are loved for a magnificent and bright color. For example, in sailing fish of this species of extraordinary beauty, a gray body with an olive sheen, on which, like a brush, transverse stripes and nacre specks form dark points.

Characteristics of Mollinesia

Aquarium species of mollies are the result of the cultivation of North American species, or their selection. Despite a number of differences, all the fish have common qualities.

  1. Females of all types of mollies are an order of magnitude larger than males: for example, Velifer's mollies reach 18 cm in length, female Latipeny - 12 cm, Sphenops - 8 cm. Sexual dimorphism is expressed: except for the difference in body size, the anal fin of a male cone-shaped (genopod), in females it is fan-like. All the mollies females are viviparous fishes that bear fry, bringing them to the light ready for full-fledged life activity.
  2. Pet shops sell different sphenops and latexes, how many of them are actually bred - only experienced ichthyologists know. Black mollies are common. Sometimes among their brood there are other forms — spotty, with light scales, or blue-green skin. New species - fork mollies, which has a “carved” tail fin, elongated in the upper and lower parts; scarf molly, in which the dorsal fin is long and elongated.


Mollies are considered one of the most beautiful fish, so they are welcome pets for many aquarists. They get along well with the swordtails. Although the swords differ in their rather restless temper, they drive very rarely.

Only now, if there are no females of the Swordtail in the flock, the “guys” will try to molest Molly, but, as you understand, to no avail. Also note that in the cramped "battle for territory" may begin, so the fish should have a lot of space.

Compatibilitys Mollies with guppies are almost perfect. Both species belong to viviparous, live in warm brackish water, like sunlight and dense vegetation. If breeding is also included in your plans, then before giving birth to the fish, you should be separated from each other, and after the appearance of the offspring, you should also remove females, as they sometimes are not averse to eat their own fry.

In general, mollies can be contained along with:

  • All kinds of petsilium and catfish,
  • Iridescents,
  • Tetras
  • Gourami
  • Labeo.


Black mollies are a favorite fish in the USSR

Black mollies are so called in the common people of aquarium fish of the genus Petsilia. There are several varieties of them. She received the most distribution in the Soviet Union. Aquarists still prefer just a few types of mollies or molly. In addition to these names, you can find other options: sphenops, Latipina, lira-molly, paresna, broadleaf Velifera. The name originates from the generic "Mollienesia". The natural habitat is considered freshwater and slightly brackish waters of Central America.


All types are similar in form. They represent the usual rounded bodies and tail fins of the lyroform. Breeders received a slightly modified form - slightly impacted. Such fish are called disc. These fish have disrupted natural proportions, which make them seem unattractive to many. But lovers of exotic fish happy to replenish their collections with black mollies.

In the photo you can track how changing color ryki. Black mollies can be dirty yellow or spotty. It depends on the habitat and the content of the fish. In the European part of this fish appeared relatively recently, about 150 years ago. In the forties, the black coloring of this fish was considered the most popular, so a real hunt began behind the dark fish. In the USSR, black mollies began to spread only from the 60s.

Black mollies not rarely compared with the usual swordsmen. Indeed, the resemblance of fish is surprising, but mollies have wide tail fins and more voluminous dorsal fins. In the wild, they can be confused with the specials.

Look at the photos of these beautiful viviparous fishes and see why they deserve an honorable place in most aquariums. Special attention is attracted by the wide-fledged body, which has an olive-gray color with small darkening spots. Males have five thin transverse stripes on which pearl specks can be seen. With proper care and maintenance, the male aquarium fish can reach 6-7 centimeters, and the female - 8. In nature, their size varies from 10 to 15 centimeters. The beauty of this fish is easily distinguished sexual characteristics. The male has a special organ - gonopodia. If you look closely at the photo, it is not difficult to notice.

One of the most beautiful mollies is recognized by Velifers. Due to the high large upper fin it is called sailing. Thanks to the efforts of breeders today you can find red, brown-golden, black and even marble colors.

Despite its small size, black mollies are demanding of conditions. With proper care, individuals can live in an artificial reservoir for up to 8 years.


Molliesia is not suitable for newcomers. Only experienced aquarists can afford it, as it is difficult to maintain proper water levels.

Mandatory conditions:

  • Spacious aquarium;
  • Salted water;
  • Temperature from 24 to 26 degrees;
  • The absence of drafts and a sharp drop in the thermometer;
  • Abundance of plant foods;
  • Bright cleansing;
  • Active filtration and aeration of water;
  • Periodic water change.

You need to change the water at least once a week. It is preferable to pour no more than 1/3 of water. These fish are peaceful enough and do not touch the neighbors of similar sizes. It is important to provide shelter for them, various snags, thickets and stones - to cope with this task. If the neighborhood is too close, then the males begin to fight for the territory. It is optimal to have 25 liters of water for one fish. Mollies prefers the middle layer of aqua. If you plan to breed offspring, then one male is enough for several females.

The content of mollies means feeding with plant food. Fish will not refuse from lettuce and oatmeal. Thanks to such feeding, the fish grows faster and looks much more beautiful, it can be seen in the photo. If you only brought home fry, then you need to feed them in large portions as often as possible. When the fry begin to grow, the diet is reduced to 1 time per day.


Young fish are ready for breeding as early as 9-12 months, females about six months. Young males are deposited in another aquarium, so that they do not begin to upset females that have not reached puberty. Will have to isolate until all the fish do not "mature". It is proved that the most beautiful fry are obtained from large and spectacular producers. Bearing offspring last about two months. A large female is capable of bringing 240 tadpoles at a time. In order to increase the chance of survival, only large and beautiful fry are selected. To fins develop larger, the temperature in a salt aquarium is best lowered. This inhibits the development of fishes, but a beneficial effect on aesthetic moments.

Reproduction in the general aquarium is not possible. Juveniles will be prey for more mature individuals. For successful breeding create a spawning aquarium.

Requirements for spawning:

  • Volume from 40 liters;
  • The presence of a large number of plants with small sheets;
  • The temperature is about 25-26 degrees.

For feeding use live dust, Artemia and Nauplii cyclops.

Mollies: reproduction, maintenance and care

Molliesia is a viviparous fish, which does not bring much trouble and pleases both novice aquarists and experienced ones. This fish is from the coastal waters of small fresh and brackish waters of Central America.

Aquarium mollies are represented by many species that have different colors and appearance, although they all belong to the same order. Males and females of various species can be kept and bred in the same aquarium. Prefer upper and middle layers of water. During daylight, they float throughout the area independently and in flocks, in the dark - they group together into one flock and keep the upper layer of the water column.

Maintenance and care

The fish is omnivorous, but vegetable feed should prevail. Mollies eat up small-cell and filamentous algae (which they participate in cleaning the aquarium), with a lack of food supply they begin to nibble the plants. Very fond of Ritchia and its young shoots.

The aquarium should have constant aeration, filtration and weekly water changes. Feed adults need once a day. This species is peaceful, quietly transfers the community of other fish, while it is well crossed with representatives of related species.

Among aquarists, the following types of mollies are very popular:
  • black lira
  • sailing,
  • Velifera sailing with various color otlasy scales (brown, green, blue).

They love clean, clear water, bright lighting and algae thickets.

The main differences between males and females are the presence of gonopodium, in males the shape of the body is slimmer, with large fins, brighter coloring. The body length of an adult individual is 8 cm; the male is shorter than the female.

To care for mollies suitable aquarium from 60 liters, with the ability of fish to swim freely, with the presence of dense vegetation.

Summary of aquarium mollies

Number in the aquarium - 4/4 pcs. (male / female): no more than three females per male

Aquarium volume for:

  • fish of one species - 80 l;
  • 112 species of various kinds.

One cm of water is necessary for one cm of fish length.

Water parameters:

  • pH 7-8;
  • dH - 5;
  • comfortable temperature is 25-26 ° С, but can vary from plus 22 to plus 31 ° С. Up to 22 degrees, the fish will not die, above 26 - therapeutic temperature;
  • hardness 20-30 dGH.

Food used: TSZZH (T - for herbivores, C - dry, H - frozen, Zh-live).

Recommended part of the water change: 20-30% weekly.

To improve the well-being of mollies, sea salt is added to the aquarium water at the rate of one teaspoon per 10 liters of water.

Reproduction of mollies

In the presence of comfortable conditions, mollies bring posterity within a month after settling. During reproduction, the male uses gonopodia, in which there is a chute for transferring seminal fluid to the female, and a hook, which allows it to keep better during fertilization, increasing the chances of pregnancy. Only one of 10 copulations ends in success. Sexual maturity is reached at the age of 8-12 months for males and 5-6 months for females.

Fry care

Successfully fertilized, the female bearing the fry is distinguished by a dark spot in the lower abdomen, near the anal fin, and a large belly. The duration of pregnancy in mollies is about four weeks, after which the female produces up to 100 fry, with age and growth large mollies can give birth to 250 fry.

There is no need to create special spawning grounds for black mollies, since they do not pursue their offspring.

After giving birth, the female remains slightly fat, because at one time she does not give birth to all of her fry, but continues to carry fertilized eggs. Due to this, the female can produce offspring for 6 months without male participation.

The most successful breeding takes place in an aquarium with various types of mollies. Fry are born quite large. For their rapid growth you need to use vegetable and live food of the appropriate size, you can feed dry food, pounded or crushed into dust. To get the dust enough to put a certain amount of feed in a mortar and carefully crush. Special fry food available at pet stores. Feed you need often and abundantly.

A couple of words about buying mollies

In the recent past, guppies were considered the most suitable fish for beginners, but now everything has changed. Many species of viviparous fish began to be bred in large quantities in South Asia.Depending on the markets, they are grown according to certain standards, using hormones and antibiotics, because of which the price of fish and its endurance directly depend. Poor survivability is compensated by a low price.

It is best to buy mollies from European breeders or adult producers from personal acquaintances. Wild types of mollies are practically not common in pet stores, they are difficult to obtain, but it is not difficult to care for them.

On the video you can clearly see how the birth of mollies goes:

Types and names of aquarium mollies

Mollies - small fish, representatives of the family Petsilievye, genus Petsilii. Habitat is quite diverse - fresh, brackish and saline waters of different parameters of temperature, hardness and acidity. The varieties of the Petsiliyevs (Latipins and Sfenopses) have morphological differences, they are accustomed to different conditions of life. Mollies are fish that live where the water temperature is constant, so keeping and caring for them is not always easy for the beginner.

Sphienops mollies are found in the waters of Mexico and Colombia, Latipina mollies can be found in the brackish canals of the states of Carolina, Texas, Virginia and Florida, and the Velifer mollies can be found only on the Mexican Yucatan Peninsula.


Aquarium species of mollies are the result of the cultivation of North American species, or their selection. Despite a number of differences, all the fish have common qualities.

  1. Females of all types of mollies are an order of magnitude larger than males: for example, Velifer's mollies reach 18 cm in length, female Latipeny - 12 cm, Sphenops - 8 cm. Sexual dimorphism is expressed: except for the difference in body size, the anal fin of a male cone-shaped (genopod), in females it is fan-like. All the mollies females are viviparous fishes that bear fry, bringing them to the light ready for full-fledged life activity.
  2. Pet shops sell different sphenops and latexes, how many of them are actually bred - only experienced ichthyologists know. Black mollies are common. Sometimes among their brood there are other forms — spotty, with light scales, or blue-green skin. New species - fork mollies, which has a “carved” tail fin, elongated in the upper and lower parts; scarf molly, in which the dorsal fin is long and elongated.
  3. Reproduction in all mollies - viviparous, and among all viviparous molly - the most unpredictable fish. Care of them is very difficult: the temperature of the water in the aquarium should be constant, the volume of water in the tank should be sufficient for free swimming, about 10 liters of water are required for 1 adult fish. Fish live in the established biological environment: crystal clear liquid enriched with oxygen. Permissible parameters of the aquatic environment: temperature 24-30 degrees Celsius, hardness - 5-25o, acidity - 6.5-8.5 pH. Updating 20-30% of water once a week is necessary.

Look at the mollies of different colors.

Maintenance and care

Molliesia prefers a large space, where there are many free swimming sites. Loves lighting, dense thickets, snags, rocks and shelters. You can see that it moves in the upper and middle level of the aquarium.

Mollies - very capricious fish. It is possible to take care of it with constant monitoring of water parameters in the nursery. If the water temperature drops, or the quality of the water deteriorates, the fish will press the fins and begin to move sluggishly, or lie down on the bottom, clinging to a certain place. To remedy the situation, you should gradually increase the temperature of the water, updating its part to a more recent one. Experienced aquarists recommend adding sea salt to water at the rate of 2 grams per liter. It is better to keep mollies with related perennial representatives of the genus Pecilia. How many species exist is indicated below.

Watch a short video about mollies content.


Mollies give birth to fry independently, not carrying caviar. It becomes sexual maturity at about 8-12 months. Fry develop in the womb of a female 30-45 days. Breeding often occurs in the general aquarium, and the birth of offspring - in a separate, prepared spawning. At one time, the female brings 30-60 fry. After the birth of the young, the female is usually removed from the spawning farm so that it does not eat the offspring. Fry mollies should live in clean water, which is recommended to be updated frequently. For the prevention of diseases, water is salted. Fry starting foods are Artemia, Cyclops, live dust and egg yolk.

Some representatives

The genus Pecillia has 33 species. Some of them:

  • Mollies red leopard is a bright but rare representative of the genus. This molly is able to get on with commensurate fish of a similar nature, reaches the size of 10-12 cm. It should be placed in an aquarium with dense vegetation, where there is a place for free swimming. Plants with light leaves are perfect for decorating the tank. With a lack of vegetable feed, can eat young shoots. Prefers the middle layer of the reservoir.

A pair of such fish can live in a 70-100 liter aquarium. Care: permissible water parameters - temperature 22-28 degrees, hardness 10-15 °, acidity 7.0-8.5 pH. You can add salt to 8 ppm. Once a week to update 30% of water, you need to filter and saturate the water with oxygen.

Feed the ice cream and dry food, herbal supplements. To enhance the color of scales, it is recommended to add food with carotenoids.

  • Mollies silver snowflake - this species does not exist in the wild, a hybrid of sailing mollies, which was bred in the 90s of the twentieth century. The snowflake has become popular among razvodchiki due to the delicate silvery coloring of scales. When the body is exposed to sunlight, it glows with blue shimmer. Peaceful, undemanding fish, easy maintenance. He likes dense vegetation, where he hides from the harassment of neighbors. Compatible with proportionate viviparous fishes. Body size from 5 to 14 cm.

For it, you need to install an 80-400 liter aquarium (if the flock is large). Care: permissible limits of water parameters - temperature 22-27 degrees, hardness 8-25 o, acidity - 7.0-8.0 pH. Salinity of water can be increased to 5 ppm. It feeds on dry and frozen feed, plants, additives with spirulina.

  • Yellow mollies - a bright fish, a contrasting yellow color scales, one of the most popular viviparous fish. Maximum body size - 5-6 cm. Homeland - freshwater rivers of Colombia and Mexico. They also like abundant vegetation in which they hide and hide. Care: permissible parameters of the aquatic environment - temperature 25-27 degrees, acidity 7.0-8.0 pH, hardness - 8-25o. Aquarium water can be updated daily. At 10 liters of the tank, you can add 1 teaspoon of sea salt, also live in salted medium. Filtration, aeration, periodic heating are recommended. Feed should be scalded lettuce, algae, feed with spirulina. Underwater "vegetarians" - fish is not without plant food. Yellow mollies are prone to overeating, sometimes you can arrange unloading diets. The nature of the fish is cheerful and peaceful, like all live-bearing pets.
  • Bellfish patchillia, Velifera mollies is a fish that lives in freshwater bodies of Mexico. It features a pronounced dorsal fin resembling a sail. Velife reaches the size of 10-14 cm in captivity. How many live - there are no exact data, but aquarium representatives can live 5-6 years under favorable conditions. The color of the body is gray-gray or bluish-silver. Care: permissible parameters of the aquatic environment - temperature 22-28 degrees, hardness 10-25o, acidity - 7.5-8.5 pH. In the water, you can add salt or salt in the proportion of 1 teaspoon to 4 liters. Aquarian residents prefer plant food, sometimes you can give live food - insects and daphnia.

How to care for a black molly?

Molliesia (lat. Mollienesia, Poecilia) - the name of the fish of the genus Pecillia. There is a popular aquarium fish with black scales - mollies black. Other names of this fish: mollies lyre, sphenops mollies, black molly.

The black low-claw molly is a breeding species that has emerged as a result of the rigorous selection of Poecilia sphenops fish from several generations. In 1926, mottled mollies were made by sphenops, and in 1936 - black velvet. However, scientists have long argued, who is the true ancestor of black mollies - sphenops or latipin? Even in the USSR, this fish did not have a common name.

Reproduction occurs in a vivifying manner: fry are born ready to live. Keeping a fish and caring for it does not require special preparation for a responsible aquarist, so it quickly spread to domestic nurseries. It has a peaceful nature, high endurance, undemanding content. In pet stores is cheap, reproduction is easy - fry live independently.

All members of the genus Poecilia are endemics of North and South America. They live in the confluence of rivers in the ocean, that is, in salted water. Many species appeared in nurseries at the end of the 19th century, and in the 20s of the 20th century, the first hybrids were bred. Among them are black aquarium mollies, snowflakes, silver and spotted molly. The number of such forms is growing rapidly due to the emergence of new colors.

This aquarium fish is an excellent choice for an amateur; its maintenance is possible in a small tank with water. They love to swim among dense thickets, and eat plant food.

For novice aquarists, the best choice is the black mollies sphenops, as it is less demanding, easy to breed, and adapts to smaller aquariums. For the maintenance of this species you need a well-overgrown aquarium, spacious. It is important that dietary fiber and algae are present in the diet.

External characteristics

Black mollies were artificially bred in 1930. Body size - from 6 to 10 cm in aquarium conditions. Lives 3-4 years. Sphenops have a coal-black body resembling dark velvet. The tail fin looks like a lyre. Females are larger, with a rounded belly. Males are smaller, anal fin cone-shaped.

The most valuable specimens are molly with velvet black scales, on which there is not a single speck. They have black eyes that are almost invisible. Their peculiarity is that due to the matte deep color the body of the fish does not shine at all.

How to feed black mollies

Black splenops mollies are small fishes that eat almost all the food that the host will give. Prefer dry, frozen and artificial food. They require high-quality, high-fiber plant food. In Mexican waters a lot of vegetation, which they used to nibble their lips. Mollies scrub growths appearing on the glass and tank décor.

Care for molly requires regular feeding. Give the fish vegetable food with spirulina, or sliced ​​cucumbers, zucchini, lettuce. Add to the diet animal feed: brine shredder, pipeker, bloodworm. It is not difficult to feed sphenops, only do not forget about the fiber necessary for them.

How to maintain and care in the aquarium

You can settle several fish in a 60-100 liter nursery with water, perhaps you decide to support other fish there. In a small container, the mollies will be cramped and uncomfortable. The conditions of the aquatic environment are as follows: water temperature is 24-28 degrees, acidity is 7.0-8.0 pH, water hardness is 20-30o.

Watch a video about the maintenance and care of mollies.

Molly dwell in the salt water of the bays, some breeders recommend adding some salt to the water. On the one hand, this is a necessary condition, on the other - the rest of the aquarium will be against such water, it is not suitable for everyone, care should be optimal for everyone. When only mollies live in the aquatic environment, water can be salted.

It is recommended to decorate the reservoir with dense thickets of plants from which the molly will feed on green algae and bloom. Install an internal or external filter. It should be updated 1/5 of the water every week, because the animals create a turbid environment. Caring for fish is not difficult - the mollies sphenops are an unpretentious creature who will thank you for your love for yourself with a beautiful and healthy look.

Black mollies will make the company a harmless and peaceful tailed water world. They are compatible with small fish with a peaceful disposition. Predatory and aggressive fish, even small ones can damage mollies. The viviparous representatives of the underwater world, such as guppies, swordtails, patsilias are the best housemates.

See how the fry of mollies appear.


Reproduction of viviparous fish - mollies sphenops bears and gives rise to fry formed and ready for life in water. Fry do not come out of the eggs, unlike the calves. A pregnant female carries cubs for a month (perhaps 30-40 days). A female's well-rounded abdomen is likely to develop new fry in it.

It is not necessary to prepare spawning. Females are able to give birth every 40-45 days of new offspring. To fry did not die from the "appetite" of the parents, the content of the female may be separate for some time. Newborn molly fry already formed, immediately begin to look for food, they do not require special care. The first feed - pounded food for fish. For rapid growth, you can add artemia naupilia and chopped pipemaker.

Unusual appearance of mollies "balloon"

Mollies balloon - artificially derived aquarium fish, which was obtained due to the long-term selection of latipine mollies from the species. The fish has a peculiar physique, a bit like a balloon filled with air. The shortened body does not allow the organs to work well, so the fish requires close attention from the person. Despite this shortcoming, the molly balloon is a popular aquarium dweller, which amateurs are not afraid to breed.

Mollies (lat. Poecilia) - viviparous fish, which belong to the genus Cartozubie, family Petsilievye. Thanks to the selection, different color forms of these fishes are derived. Natural habitat - fresh and saline waters of Latin America, from Mexico to Colombia. For the first time they came to Europe at the beginning of the twentieth century. Males mollies less than females, in the wild, representatives of this species reach a length of 10-16 cm, in captivity, they are less - 6-8 cm. The content of mollies is possible in home aquariums.


Mollies balloon characterized by a shortened body (short spine). In addition, the ridge has a curvature. The body length of the fish does not exceed 5-6 cm. The large abdomen is the result of the species modification. The internal organs are small, tight.

The color of the body resembles the scales of mollies of latex, however, individuals of other colors are bred: red, orange, gray, black, silver. It is easy to distinguish the female from the male - the males have an anal fin (genopodia) of a cone-shaped shape, in females it is rounded. Viviparous reproduction - fry appear ready to live in water. Live balloon from 3 to 5 years.

Look at the variety of colors mollies balloon.

How to contain mollies balloon

Keeping fish is possible in a small or medium aquarium, depending on the number of fish living in the tank. In a spacious nursery, fish grow more than in a small one. In a 10-liter aquarium, the fish will grow no more than 3 cm in length; in an aquarium over 100 liters it will become 10 centimeters.

Favorable neighborhood mollies with the following fish: scalar, barbusses, males, danios, guppies, battles, other types of mollies, rasborami, iris, swordtails and tetras. Incompatible with cichlids, astronotus and all kinds of goldfish.

Molly balloon prefers terrain with abundant vegetation and ample swimming. Therefore, the back of the nursery is recommended to cover with thick plants, and the front window should be left free space for movement and games. Suitable plants such as: Elodieus, Echinodorus, Javanese moss, Vallisneria, cryptocoryne. Soil for the tank - medium-sized dark gravel. These fish are demanding to the lighting of the aquarium - the light day should last at least 13 hours.

Parameters of the aquatic environment: the water temperature is 23-25 ​​degrees, the extreme temperature threshold makes fish breeding impossible. The acidity of water is 7.0-8.5 pH, hardness - 15-25o. It is better to update the water regularly, 1 time per week 25% of the total. You can also add salt to water in proportions of 2-3 grams per 1 liter. No less important is the presence of snags, stone slides for shelters and dense thickets of aquarium vegetation. In the absence of high-quality water, the molly become slow, pressing their fins to their bodies, sometimes lying in one place and swaying.

Feed the mollies balloon can be small crustaceans, bloodworms. Some razvodchiki not advised to give the pipe worker, because he is able to injure the already delicate internal organs of digestion. Vegetable supplements are mandatory - filamentous algae, scalded cabbage leaves, lettuce leaves and dandelion. With a lack of fiber, mollies begin to eat young shoots of aquatic plants.
