Mollies fish aquarium


Mollies: content, types, compatibility, breeding, photo-video review


Habitat mollies is very wide. In addition, the natural habitats of various types of mollies consist of fresh water, brackish water bays, and even sea coasts. Velifer molliesia populates only lakes and rivers of the Yucatan Peninsula in Mexico. Latipina mollies inhabit the brackish waters of Virginia, Florida, Carolina and Texas. Sphinops mollies live in a variety of reservoirs in the territory from Mexico to Colombia.

Latin name: Poecilia.

Family: Pecilia.

Comfortable water temperature: it is below 25 degrees, better than 27. Mollies are thermophilic, the temperature drop is poorly tolerated.

PH Acidity: 7-8, which is typical of many viviparous fish - they love a weakly alkaline environment.

Aggressiveness: Peaceful, but nimble - shebby fishes.

How many live: up to 4 years.

The complexity of the content: lekaya

Compatible mollies: viviparous fish - platies, swordtails; labyrinth - gourami, lyalius; non-aggressive and small dwarf cichlids", angelfisheven cockerels (It is worth noting that scalar and cockerel are soft water fish, which is not very similar to the parameters of water for mollies).

The volume of aquarium for mollies

In our opinion, the minimum size of an aquarium for keeping a small group of mollies is 50 liters. These fish are very mobile, so the ideal size for the content of mollies will be 100 liters. You should not keep fish in small and narrow aquariums.

Maintenance and care of mollies

In the aquarium, it is desirable to create a stable biological balance environment. All types of mollies are quite thermophilic and prefer water with a temperature of 25–27 ° C, they do not tolerate temperature fluctuations.
Like all fish, mollies love fresh water, so systematic is desirable - once a week, replacement of aquarium water in a volume of 1/4. This manipulation will ensure the absence of high concentrations of nitrogenous compounds in the aquarium - ammonia, nitrite and nitrate. When making water changes, you need to strictly monitor the temperature regime. Filtration and aeration of water is required.

Most of the time the fish are in the upper and middle layers of the aquarium. Optimally light day for these fish should last at least 12 hours, so you need to equip the aquarium open, well-lit areas. No less important is the presence of stones, koryag, thickets of plants, etc. for shelter.
Mollies is an active fish, moderately friendly. Keep it better in a group with a predominance of females. It can live both in the general aquarium and in a separate one. It gets along well with diverse neighbors. In general, the fish "neighbors" should be about the same size. Between themselves, mollies get along well - intraspecific aggression is poorly pronounced, but at the same time in the close aquarium males can chase each other. Therefore, it is better to provide a spacious aquarium so that at least 10 liters of water are needed per individual.

Feeding mollies

Mollies are omnivores, their diet should include a sufficient amount of plant food. Feeding any fish should be correct and varied, it is a guarantee of good health. These fish are great to eat any dry and live food. Mollies are very voracious, so it is important not to overfeed them, so as not to have problems with digestion.

Feeding any aquarium fish must be correct: balanced, diverse. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses. Article "How and how much to feed aquarium fish" talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing - feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company "Tetra" - the leader of the Russian market, in fact, the range of feeds of this company is striking. In the "gastronomic arsenal" of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry. Detailed information on all Tetra feeds, you can find on the official website of the company - here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state - this will help avoid the development of pathogenic flora in it.

Types of mollies

Mollies are very diverse in appearance and color. But there are three main types:

Mollies sphenopsor black. Beautiful fish, black as pitch.

Velifers mollies, she sailing or high-grade. This is the largest species - it reaches 10 cm and more, it has a large, kassivny dorsal fin.

Latipina Mollies - "a reduced copy" of the mightiest of the Velifer.

The remaining mollies are variations of these three species, differing in the shape of the caudal and dorsal fins, in coloration, and sometimes in size.

Reproduction and sex differences of male and female mollies

Male from female can be easily distinguished, sexual dimophism is well expressed. In males, anal fins form gonopodia. In the presence of comfortable conditions mollies bring offspring monthly. 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. Sexual maturity is achieved by fish about a year of life for males, for females by half a year.

Pregnancy lasts about one and a half months (35 - 45 days). The signs of a female's pregnancy are a dark spot in the lower abdomen and a raised belly; such a female begins to seek refuge in the nooks of the aquarium. It is advisable that such a female be deposited in a small, spawning aquarium with water whose parameters are identical to the water from the common aquarium.

Spawning usually occurs in the early morning. In large females, up to a hundred fry can be born at the same time, their number depends on the age and size of the female. Fry of mollies are born quite large, they do not rise from the bottom immediately, at first they lie on the bottom and leaves of the plants. Fry mollies are very sensitive to water pollution, so in the aquarium, where they are located, they recommend more frequent water changes than usual. In order to improve the immunity of fry, water can be slightly salted.

For the rapid growth of the fry need a varied diet, they feed "living dust", pounded with high-quality artificial food or special food for fry.

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.

Brief characteristics of the aquarium for the maintenance of 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.

At least 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:

How to reproduce mollies at home

Mollies - viviparous fish, a representative of the family Pecilia. Homeland of mollies - fresh and brackish ponds of Latin America. In the home aquarium, you can find different types of mollies, which were cultivated or bred by humans as hybrid breeds.

Despite the many species that differ morphologically, all share one trait - females independently give birth to fry, and do not lay eggs. Molliesia, reproduction and breeding of which is possible at home, can bring offspring both in the general aquarium and in the prepared reservoir. Spawning mollies is possible one month after settling in the nursery of adult fish.

Conditions of keeping and breeding fry

Males and females of different types of mollies may be neighbors and not in conflict, therefore, living in an aquarium with a company of other fish is only a joy for them. They prefer to swim in the upper middle layer of the tank. During the day, they move alone or in small schools (flocks), and at night they form one joint, swimming in the upper ball of the reservoir.

In order for different types of mollies to live comfortably in an aquarium, 10-20 liters of water are required for 1 individual. For fish of one species, an aquarium of 80 liters, for different species - 110-120 liters. At least 3 females should be settled on one male. Fish can breed in the general aquarium (on the condition of a small population) or in a prepared breeding ground. To breed the fry, producers need to be fed for 2 weeks with vegetable food.

Look at the spawning of mollies.

Comfortable conditions of maintenance guarantee spawning in a month or two after settling in a new "house". The cone-shaped organ of the male genopodia is used for fertilization of the female: seminal fluid is transmitted through it, it also allows you to hold onto the female during breeding, and the ability to become pregnant increases. In fact, pregnancy does not come so easily. Only 1 in 10 copulations ends successfully. Males become sexually mature at 8-12 months, females at 5-6 months.

Breeding of all types of mollies is not difficult for the responsible aquarist. However, the fry of this fish are sensitive to water parameters, in particular, to its pollution, so you will have to change the water frequently.

With successful copulation, the male fertilizes at once many eggs, in which the fry begin to develop. Some mature and are born, others remain inside the female until the next generation. In the absence of a male in the aquarium, the female can give birth to another 35-50 days at intervals.

How to care for fry

A pregnant female has a square belly, from the side it may seem that it reaches the head. On the abdomen, from the anal fin, you can see a spot. Pregnancy lasts one month, after which the female gives birth from 50 to 100 fry. Before giving birth, the female tries to find a secluded place - if in the general aquarium, then in the shade and thickets. It is necessary to replant it in a separate spawning 2-3 days before the birth, but not on the day of birth! Otherwise, she will get a lot of stress. Mature mollies give birth more, for the second birth the female brings more than 200 fry.

Molly is not aggressive to his offspring, although there have been cases of eating fry, sometimes random. Often the female is transferred to a separate container with water, where she produces fry. After birth, it is deposited, and the fry continue to grow and develop. After childbearing, the mollies female still has a large abdomen, which means that she did not give birth to all - some already swim, and others mature and appear later. Newborn fry rather large.

Starter feed for calves - vegetable, liquid and live feed for fry, sometimes they are given pounded to dust feed for adult fish. Feeding in small portions, but frequent (2-3 times a day).

See how the fry of mollies appear.

It is important to know

Molly breeding in general or in a separate aquarium is at least not difficult, but you should know some features of the behavior and content of both producers and fry.

  1. Females larger and more mature give birth to more fry than young ones.
  2. Fry mollies are large, but with a weak body, unlike fry guppies and swordsmen. They swim to the surface of the water in a few days, and in the first days of life they lie in the aquarium at the very bottom, sometimes on the leaves of the plants.
  3. Molly fry require frequent replacement of aquarium water, so as not to die.

  4. Salted water (1 tsp per 20 liters) increases their immunity.
  5. If the conditions of the aquarium do not meet the norm, the producers do not give birth to healthy offspring, or do not breed at all. In the worst case, the female gives birth to dead fish or premature eggs.
  6. The reason for the unsuccessful spawning may be a tight reservoir, a very high water temperature (over 28 degrees Celsius).
  7. The main fry feed is ground vegetable food, Artemia naupilii, Cyclops, live dust (ground).
  8. After maturing the fry, they are seated in "opposite-sex" aquariums. Molly females are larger than males; males have a con fin-shaped anal fin - genopodia. In females, anal fin is rounded.
  9. Black mollies sometimes give birth to fry with spots on the body of green, blue. There is nothing terrible in this: mollies from wild nature have a solid and brighter body color, therefore such “tags” are a sign that all hybrid molly are descendants of Latin American natural species.

Aquarium fish mollies balloon: description, photo, content, reproduction

This beautiful aquarium fish was artificially bred during a careful selection of representatives from the mollies species of latypin. Mollies balloon has a very unusual constitution - it resembles a balloon filled with air. The body is shortened, which does not contribute to the normal functioning of the internal organs, so the fish needs close attention from the person.

Despite this, mollies balloon - this is one of the most popular aquarium inhabitants, which is bred by many fans of the underwater world.

External features

Molliesia, which photos often adorn publications for aquarists - viviparous fishes. The natural habitat is the saline and fresh waters of Latin America, from Colombia to Mexico. Males of mollies are much smaller than females, in nature representatives of the species reach a length of from ten to sixteen centimeters, in the aquarium they are much smaller - do not exceed eight centimeters.

Molliesia, whose photos you can see in this article, were found in the southern part of the United States and Central America. To breed it in aquariums began in 1899, and the first hybrids appeared in the 20s of the XIX century. Under natural conditions, they are colored yellowish gray or silver and have blue, bluish, green or black spots. The abdomen is usually lighter than the back and spotless. The body is short, dense, the fins are strong and wide. However, in the course of hybridization and cross-crossing, numerous variations of colors were obtained.

Mollies: a description of the type of balloon

This species also has a shortened body, with a noticeable curvature of the ridge. Fish mollies balloon does not grow more than six centimeters. Its feature is a large abdomen. It is the result of a modification of the species. The internal organs are tight and small. Body color is somewhat reminiscent of the latex mollines. But today individuals of other shades are widespread: orange, red, black, silver, gray.

These fish are very much decorate the aquarium, so for many lovers it is important that in their underwater kingdom lived a mollies balloon. How to distinguish the female from the male? Quite simply, males have a genopodia (anal fin) conical, with females it is round.

Mollies balloon: content in an aquarium

These cute fish are not suitable for densely populated small aquariums, although they are quite hardy and survive even in such conditions, subject to regular maintenance and care of their home. When the pH of the water falls due to excessive levels of organic matter, the fish may suffer. In the aquarium for mollies should be carried out regular replacement of water. A quarter of the total volume changes every 2-3 weeks. If the aquarium is overpopulated, it should be done more often.

There is another feature of the content of mollies balloon: you need to add two and a half teaspoons of aquarium salt to every ten liters of water in the water. Do not forget to add salt water when changing. If you add water due to evaporation, then there is no need to add salt, since it remained in the aquarium.

Despite the fact that these fish prefer salt water, they feel great in fresh water, but on condition that it is not too sour and soft. Water should be alkaline and hard.

Aquarium decoration

Mollies balloon needs live plants in the aquarium. Fish love greens, especially when it is able to diversify their diet. But try not to overdo it with landscaping - mollies need a place to move. Plants floating in an aquarium help fry to survive, and some of them are additional food. Do not get involved in picturesque snags - they reduce acidity, but for viviparous fish this is undesirable.

Any substrate can be used for the substrate, although on a lighter mollies the balloon will better demonstrate its beautiful color. Good filtration is required, which will allow to maintain stable water performance. In addition, in well-treated water, the males show their best colors.

These are quite active fish that need a large space for swimming. If there are few fish, the minimum volume of the aquarium should be at least 55 liters. If you contain a group of mollies, then it should be increased to at least 75 liters, and the ratio should be as follows: one male per three females. This will help you avoid quarrels between males. Preferred water temperature: 21-28 ° C, pH: 7.0-8.5, hardness - 20-30 dGH.


Although experienced aquarists believe that the mollies balloon is an omnivorous fish, we must not forget that it is characterized by a high need for plant foods. The diet of this variety should include a lot of algae and other vegetarian food. In nature, their diet consists mainly of rotifers and algae. Small aquatic insects and crustaceans make up an insignificant part.

In the aquarium mollies, the balloon eats ready-made feeds and live foods with pleasure, but it appreciates a large amount of plant food. Vegetable flakes in combination with blanched spinach and fresh cucumbers will be an excellent addition to the basic diet. Do not forget to clean the remaining food in a timely manner. Between feedings, mollies will be happy to eat with aquarium plants and some aquarium algae.

These fish also will not refuse protein food, but they cannot exist solely on it. Treat them from time to time with artemia (live or frozen), bloodworms, pipemaker. Meals should be varied, several times a day. Feed in small portions, in such quantity that it will be eaten in three minutes.

Mollies balloon: breeding

Mollies - viviparous fish: the offspring are born completely adapted to life in water. The life span of this species is from 3 to 5 years.

Mollies easily breed in an aquarium, and the offspring very quickly reaches puberty. Depending on the size of the fish and the age of the female gives birth to a hundred young fish. In addition, a feature of viviparous fish is that male sperm is stored in the female's body for a long time. This allows you to give birth to fry several times, even if the male is removed from the aquarium.

For breeding, you only need to purchase individuals of both sexes, and these fish will overpopulate the aquarium in a short time.


A pregnant mollies balloon is clearly visible in an aquarium: a dark spot appears in the lower abdomen next to the anal fin and a large belly. Pregnancy at mollies lasts about four weeks, after which fry are born. Many aquarists say that with age, the largest individuals are able to give birth to two hundred and fifty fry.

In the general aquarium, offspring can be eaten by older fish if they are not planted in time. Can be used to protect floating plants. After giving birth, the female does not immediately restore her "figure" - for some time she still remains a bit thick. This is explained by the fact that at one time it does not give birth to all the fry, but continues to carry fertilized eggs. Due to this feature, the female mollies is able to produce offspring for six months without any participation of the male.

Fry mollies

We mentioned the stamina that distinguishes the mollies balloon. Fry, unlike adults, are very sensitive to water parameters, especially for harmful impurities. Frequent water renewal is recommended. To make the offspring adapt more easily and not be afraid to eat (fry are afraid to take it in the first days of life), place Javanese moss in a container. The very first food for young fish is ground food, small ciliates.

If you have nowhere to move fry, use a five-liter jars with separated running water. Banks better put in a bright place, but direct sunlight should not fall on them.


Mollies are active, but at the same time peaceful inhabitants of the aquarium, they are very sociable, they love to live in the vicinity of their species or with other viviparous fishes. Males sometimes quarrel, but do not cause each other serious injuries. Only a few fish exhibit a character that can manifest itself in aggressive behavior. You can keep mollies with any fish that has a similar temperament and has the same requirements for the chemical composition of water.

Avoid proximity to fish that can damage the fins of their peaceful neighbors. This primarily refers to the barb of Sumatran. Bottom catfish corridors, platies, other viviparous, some types of rainbow fish will become their best neighbors. Not bad coexist with mollies tetra, carp, other haratsinovye that can live in such water parameters.


Can hurt all the inhabitants of the aquarium. Molly balloon is no exception. The most common cause of the ailments of this fish is hypothermia, inappropriate water parameters, infection. The owner of the aquarium can very quickly notice signs of an incipient disease: bumps or dots appear on the scales, and you can see raised spots and ulcers on the skin.

Mollies, painted black, sometimes suffer from a disease called melanosis. This disease occurs due to increased pigmentation of the skin, which often causes tumors. For the prevention of many diseases should strictly monitor the temperature in the aquarium, the purity of feed, soil and scenery. Sick fish must be removed from the general aquarium. They should be transplanted to quarantine in another tank and fed in a balanced manner.

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.

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.


Reproduction of mollies balloon is possible subject to optimal conditions of detention. But if the temperature of the aquatic environment is above the norm, the offspring will not leave. The reproduction of fish begins at the age of 1.5 years. A pregnant female can be distinguished by a large tummy that almost reaches the head. After the first spawning, it is able to give birth for another 30 days without a male. To leave the fry, females deposited in an aquarium with vegetation and water temperatures of 28-30 degrees.

Fry mollies balloon sensitive to all water parameters, especially to harmful impurities. Frequent water updates are recommended. The female gives birth to 50-60 small fish, which bears 30-45 days.

In order for the offspring to adapt to life, and not be afraid to eat food (the first few days of life, newborns are afraid to take it), put Javanese moss in the aquarium.

All types of mollies, painted in black light, sometimes suffer from a disease called "melanosis", which appears due to increased pigmentation of the skin, which causes tumors.

For prevention it is necessary to observe the temperature regime of the aquarium, to monitor the purity of the food, scenery and soil. You should not leave sick fish in a nursery with healthy ones; it is better to transfer them to quarantine in another tank and feed them in a balanced way.
