Percylia: maintenance and care, sexual dimorphism, species, photo-video review

All about aquarium fish

Petilia is one of the most popular and beautiful aquarium fish!

The simplicity of the content, variability of color, ease of breeding made them so popular.

Despite the fact that these fish are easy to maintain, you need to know the basic recommendations and tips for the care of the pests, so that they live and decorate your tank for as long as possible.

How many live: In good conditions can live up to four years. Find out how much other fish live IN THIS ARTICLE!

Petilia size reaches 4-5 cm. in females, males are somewhat smaller. The body is rhomboid, with a rather wide tail fin and a relatively small head.

Habitat: North and Central America. Also common in Florida, California, Colorado, Hawaii, Louisiana, Texas and Nevada.

Pecilia care and maintenance

Petsilii are considered very undemanding fish. They, as in other and all other small fishes, need clean water - ammonia concentration = 0, nitrite = 0 and nitrate is acceptable 20. Therefore, a good filtration system of water is necessary! Just need to water heaterto maintain a comfortable temperature. And of course, need aeration, it is not even discussed. It is advisable to carry out water changes once a week ~ 1/4 - 1/3 of the total volume of water.

Petsilii are very active - they like to swim very quickly. Therefore, despite the small size of the fish, the aquarium should be a volume of 70 liters, and better all 100 liters. It is desirable that the aquarium was wide and deep enough, these fish love to put them there, preferring the middle and upper layers of water.

With the content of platies, one should know and remember that these are “alkaline fish” - they prefer dH and pH above 7. It is not advisable to acidify the water with snags, tea or other physiotherapy. It is also advisable to select "alkaline" neighbors, for example, scalarians, and gourams get along well with the pecilias, but still they are not the best neighbors, since they like soft and mildly acidic water (dH pH below 7).

Feeding and nutrition of petsilians

Pitsilia willingly eat any dry food, do not disdain and any live food, for example, bloodworm. In nature, the celites feed on insects and algae. Therefore, their diet should include plant foods. It is necessary for normal digestion. However, balanced feed from the company Tetra perfectly cope with the task.

Feeding 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, arawan, 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 platies

It should immediately say that Xiphophorus maculatus - this is the view, "Pecilia spotty." There is also Xiphophorus variatus - "Pecilia tricolor". Both of them have many breeds of breeds, most of which are even hybrids between these species, with the attraction of the original form of the Green Swordsman species, Xiphophorus helleri. For example, the breed "black petilia" and "black swordtail" - the selection result of hybridization of all 3 species. Wild - the original forms of the species "spotted petilia" and "tricolor petilia" in the aquariums almost never occur.

Thanks to breeding work, more than 130 species of placium are now common in aquariums. There are red, yellow, orange, golden, and even white! It’s just impossible to list everything. There are two interesting morphological forms of the platius. The first is the "balloon".

In nature, does not occur, artificially derived. It looks very unusual because of the curved spine. When breeding were selected fish with a shortened curved spine. Pecilia balloon looks like a shortened, bloated version of the usual partilii. Due to the curvature and displaced internal organs, this morph often has problems with reproduction. The second - petilia radish.

In nature, also not found, bred by breeders. Named so because of the original shape of the caudal fin, almost always having a black color. Recently, various variations of this popular aquarium fish with a modified - shortened body, as well as with fins of various shapes, have appeared.

Pecillia sex: male and female?

On the photo, sex differences

Males and females of the patchillia are simply distinguished; in males, the anal fins are folded into a tube - gonopodia. Live-bearing varieties like guppies, swordtails and mollies, i.e. females bear eggs and fry inside the body. Pezily breeding is simple, as a rule, it occurs without any involvement of an aquarist. In an aquarium, plants are needed in which the fry will take shelter until they grow up, otherwise other fish, and even the parents themselves will perceive the offspring as live food. Pregnant placilia looks very characteristic, you will not confuse with anything. Pregnancy can be determined by the rounded abdomen and the dark spot near the anal fin. Usually, the female pecilia gives birth every 28 days, the number of fry is about 20-40 pieces. Fry appear quite independent and relatively easy to feed - living dust, pounded into dust with branded feed or special feed for fry.

Interestingly, females patzilia, like all viviparids at some point, change sex and become a male. Such behavior of viviparous fish is explained by the evolutionary struggle for survival.

Yellow, disc and other species

Pecilia (lat. Xiphophorus maculatus) is a small freshwater fish of the Pecilliaceae family. The natural habitat of the species is North and Central America. It is found in the waters of the states of California, Colorado, Florida, Louisiana, Texas, Nevada, Hawaii. Nowadays, aquarium petsilievyh are bred on fish farms or in aquariums.

All species of platies are characterized by small body size, females are larger than males one and a half times. The body length of females is 5 cm, males - 3-3.5 cm. How long do these fish live? If you provide them with proper care, they will be able to live in captivity from 3 to 5 years. The appearance of the chili can be varied - aquarium pets are mostly painted in bright or motley colors, and wild species are not on sale. Interesting morphological characteristics has a diskius, in which the body is rounded, the spine is curved. Its other name is pecilia balloon. As for the behavior, the Petsilia Disk is more capricious and whimsical in content, unlike other breeds.

Sex differences are noticeable - in addition to the difference in body size, the females of these fish are distinguished by a rounded and wide anal fin. In males, the anal fin is long, pointed, forming the so-called “gonopodia”. Females have a full and rounded abdomen, the color of their scales is faded. Males are brighter, their body symmetry is angular.

Content policy

Petsyli content in the aquarium is quite simple, so even a beginner lover of fish can provide them with proper care. All varieties of platies are viviparous fishes, full-fledged, life-ready fry appear from the womb of females. Pecilia is a lively and unpretentious fish (except for the Discillium breed), one adult fish needs a reservoir with a capacity of 50 liters. It is advisable to settle on one male two females. These fish do not show aggressiveness towards their congeners, but there should be more females in the aquarium.

Fish easily adapts to the domestic water body, the parameters of the content are also important: the water temperature is 22-26 ° C, the acidity of the medium is 7.0-8.0 pH, hardness 15-20 °. Once a week make water changes to clean, infused and fresh. Install an internal filter and compressor in the aquarium so that the water is constantly cleaned of dirt and saturated with oxygen.

Watch the video about the content and care of the red petsilia.

In the common aquarium, aquarius varieties of patchillia get along well with viviparous fish: guppies, swordtails, mollies. They can breed with these species, sometimes bringing beautiful and healthy offspring. In nature, they do not interbreed with each other. Percylievye have a peace-loving disposition, so they can become victims of large and predatory neighbors. Do not settle them with cichlids, eels, large catfish, carp, goldfish, barbs.

Wild species of species eat detritus, algae, aquatic plants, and insects. Pets can eat what the host gives, but the diet should be varied. Fish like food with spirulina, scalded lettuce and dandelion leaves, spinach, boiled cereals without salt (millet, oatmeal), sliced ​​zucchini and cucumbers. From live food they prefer Artemia, Daphnia, Tubber, Bloodworm, Coretic. You can give branded food in the form of flakes and tablets. Thanks to the upper mouth, capture food from the surface of the water. Feeding - 2 times a day in small portions, which can be eaten in 5 minutes.

Spawning Xiphophorus maculatus

The reproduction of fish is possible both in the general aquarium and in a separate spawning ground. If there are males and females in the reservoir, reproduction can occur by itself. Be prepared that females can often produce offspring, reproduction should be controlled.

Look swim in the aquarium yellow and white partilias.

Breeding between these fish is possible at the age of 8-12 months. The smaller the males in the aquarium, the calmer females feel. It is easy to notice the pregnancy of the female - she has a fuller abdomen that will swell strongly before giving birth, and a dark spot forms near the anal fin. She will find a secluded place in the pond, where the fry will appear. The young female will give birth to some fry - from 20 to 40, adult 50 and more. Shortly before giving birth, the female can be deposited in a container with clean water, where she will calmly prepare for the delivery. You can add plants to the bailout; it is better to shade the glass of the tank with paper.

After giving birth, the female will have to be carefully removed from the pitcher with the help of a net - she can eat her brood. It is easy to care for the cubs, as they are formed and ready to search for food. Starter feeding - food for fry, pounded egg yolk, Nauplii Artemia. Later they can be sorted as they grow up. The babies will become sexually mature at the age of 3 months, however, transplant everyone into different containers with clean water so that non-sexual individuals do not breed at such a young age.

Species diversity of aquarium Xiphophorus maculatus

Red Petilia is a very beautiful aquarium fish with a rich color of scales. The ventral fins shimmer with a bluish tinge. Body size - 10-12 cm, to achieve a saturated color, you need to give live food. Very fast, active pets. Red platilia is often used as a material for breeding new breeds of placium and swordtail, in aquarium conditions it can independently cross with "swords", bringing fish that resemble in appearance tricolor swordtails.

Pecilia balloon - fish of unusual appearance, which may have different color scales. Because of the deformed spine, their life is not very simple. Then how much do they live in captivity? Providing them with quality care, they will live from 2 to 4 years. The length of the body is 15 cm, height is 8-10 cm. Males are 1.5 times smaller than females.

The black black flower is characterized by a peaceful nature, it is distinguished by its active behavior and fast swimming style. Black platilla interbreed with other Pecilia, brings hybrid offspring. The resulting fry will grow with a deep black body color that will emit a bluish tint. Body size 10 cm, life expectancy 3-4 years.

Yellow platilla - small fish (8-10 cm), in males front tail part and tail of red shade. The body of females paternal is slightly larger, rounded, yellow in color, fins are transparent. Along the body of the males, there is a barely noticeable horizontal strip of silver.

Pecilia: reproduction and care at home. Petilia aquarium fish: description, content

Pezilya fish, the reproduction of which, as a rule, occurs without unnecessary trouble, is considered to be a fairly frequent inhabitant of modern living corners. It is often found not only in huge office aquariums, but also in ordinary home, medium or even very modest sizes.

In general, it should be noted that the pesilia is a fish, the content of which will not become problematic even for beginners in the world of aquarism.

This article will tell about it in sufficient detail. The reader will get acquainted with all the necessary information related to the habitats, feeding characteristics and the appearance of such an interesting inhabitant of the underwater world, such as Petsilia. Reproduction and breeding at home will also be covered in separate sections. After reviewing all the facts provided, anyone who wishes can, without further fear, get such a fish as a pet.

Section 1. General information and habitat conditions in nature

Pecilia is a fish that is a very popular inhabitant of modern aquariums. Why? Most likely, due to its unpretentiousness, easy breeding, beauty, various colors.

However, not everyone knows that its natural habitat - North and Central America. Especially often it is found in Veracruz in Mexico. In addition, it is possible to meet petilia in California, Colorado, Florida, Louisiana, Nevada, Texas, and Hawaii, but it was brought here artificially.

Section 2. The appearance of the fish

Pecilia, the content of which is not only easy, but also quite interesting and informative, is a rather small fish, its length rarely exceeds 3.5–5 cm, and the average life expectancy is within 3–4 years.

Its appearance, as well as its color, is difficult to describe due to the large variety of options. It is safe to say that the female pecelia is not as bright and variegated as the male.

Scientists distinguish many varieties. For example, it is necessary to mention disk specials. She has an unusual, very curved spine and a special body shape. But red petilia is much more mobile than other species.

Section 3. Sexual differences fish

Sex differences in these fish appear more than bright. Females are visually larger, have not so bright color, wider anal fin. In addition, they have a fuller and rounded belly.

In males, the anal fin is small and pointed at the end, the body color is beautiful and very bright. They, as a rule, are considered as the present decoration of modern aquariums.

Section 4. Necessary conditions for breeding fish

Petilia breeding is easy, as no special conditions are required for this. By the way, many aquarists even laugh, saying that it is much more difficult to stop the reproduction of these fish than to start it. And it really is.

So do you have a Petsilia? The reproduction of these inhabitants of the underwater world is not long in coming. In order for females to become pregnant normally and regularly, one male is enough for 3 females. Such an amount is optimal, as it significantly reduces the competition of males and at the same time gives females the opportunity to take a break from them.

Pekyliya are viviparous fishes, i.e., they bear eggs inside the body and a formed fry, able to swim, is born immediately. It is easy to determine the pregnancy of the female by the rounded abdomen, as well as by the dark spot near the anal fin. The female can easily give birth every 28 days, while the average number of fry is 20-40.

As a rule, the genera are easy.Although it is still advisable to plant a pregnant female in a separate aquarium and add more plants there. At this time, the expectant mother does not need to be disturbed once more, therefore it is recommended to close the front glass with paper.

Rsection 5. Care of fry

It is important to take into account that petilia eat their fry, therefore, in order to survive, you should plant many plants or immediately plant them in a separate container.

Further care of the fry is quite simple, because it is born large and fully formed. You can feed them with egg yolk, special crushed feed or simple dry. With abundant feeding and clean water, after 3 months the newborn pets will already become sexually mature.

Section 6. How to feed

In nature, the caellia, the reproduction of which occurs regularly and without any problems, mainly feeds on insects and algae. But in the aquarium, they with great pleasure eat almost any kind of feed.

It is very important to include in their diet specialized nutrition with fiber, for example, flakes with vegetable ingredients or vegetables such as cucumbers, zucchini, spinach. Such plant food contributes to the better functioning of the gastrointestinal tract. But animal feeds can be anything, for example, a bloodworm, a tubule, an artemia, a corret will work well.

Section 7. Maintenance and Care Difficulties

Pecilia, the content of which does not require special skills, is great for both beginner aquarists and professionals.

Like almost all viviparous fishes, the partilii are unpretentious and livable. They can be kept in small aquariums, from 40-50 liters. Of course, it is better that the volume was large. Petsilia do not show aggressiveness among themselves (as, for example, swordtails), and it is possible to contain them with a slight predominance of females.

As for the parameters of water, here they are also not too whimsical. The ideal option is medium hard water (15-30 dGH), acidity is desirable within 7.0-8.3, and the optimum water temperature is 22-25С. The main thing is to keep the water clean and fresh, the best option is to partially add a certain portion of water to the weekly, as a rule, not less than 20%.

Filtration and aeration, of course, is desirable, but if the aquarium is not overpopulated, it is quite possible to ignore it.

Section 8. Conditions for compatibility with other inhabitants of the aquarium

Another plus of the platies is that they get along perfectly well in a common aquarium, they don’t touch any other fish at all.

But keep in mind that for predators themselves they can become easy prey. That is why it is best to place platies with other viviparous, for example, with mollies or swordtails.


Remember the aquarium of your childhood. The one that was the first embodiment of the dream of living fish. There lived guppies, barbs and, of course, petsyli.


"Of course" - because the aquarium fish petilia is unpretentious and inexpensive, its content does not cause great difficulties. Therefore, she gained popularity with aquarists around the world. Pecilya necessarily included in the "live set" of the first children's aquarium.

Mexicans in our aquariums

Pezily genus includes more than 30 species. Their homeland is Guatemala and Southern Mexico, where they live in the mouths of the rivers of the Atlantic basin. Petsilia was introduced to Europe for the first time in 1907. Separate species of placias are distributed from the southeastern coast of North America to Venezuela.

It is a small fish (4-5 cm in length) with a short dense body and a powerful tail fin. In nature, the cestilia is colored, as a rule, in yellow-brown tones with two dark spots near the tail. Your aquarium pets, of course, much more beautiful. A variety of colors was achieved thanks to many years of selection.

The petsilia seems to be rather passive, but in fact, it is a quick fish that needs free space for swimming. This must be taken into account when keeping the placium.


Pecilia is unpretentious, its content does not cause difficulties. A fifty-liter aquarium is quite a suitable "house" for a flock of fish, and a couple can be kept even in a three-liter jar.

Petsilia is undemanding to the composition of water, but it is better to use water above average hardness. A weekly replacement of 1/3 of the volume of water will have a beneficial effect on the condition of the fish. The temperature must be maintained in the range of 22-25 C, although petsiliya can withstand eighteen degrees of water.

There are different opinions about adding salt to aquariums that contain chilias. On the one hand, this creates more comfortable conditions for the fish. On the other hand, petsilia gets used to this “medicine”, which leads to a decrease in immunity.

If the water is too cold or if you overcrowd the aquarium, the pills can be sick (colds and fungal diseases, fin rot). For treatment, it is necessary to raise the temperature of the water to 27-28C, add salt to the water at the rate of 1-2 grams per 1 liter of water, enhance aeration, change part of the water to fresh. In some cases it is possible to add biomitsin to water.

Petsilia is undemanding in food. Any live and dry food in combination with plant food is suitable: tubule, daphnia, bloodworm. Pesilia fry grow up with pleasure to eat Cyclops.

"A wonderful neighbor has settled in our house" - exactly about the piece. It is non-aggressive, gets on well with other species of fish, can coexist with snails and non-predatory shrimps. Aggression is manifested only in relation to their own most brightly colored fry. In this way, the Pecilya conducts breeding aimed at combating the bright colors of the species. Ahead of the fish in breeding work - this is the task of an aquarist.

Breeding and breeding

Pecilia - viviparous fish. The male has a fertilizing organ - gonopodium. Caviar is fertilized in the body of the female. Fry are born fully formed.

If breeding occurs in the general aquarium, take care that there are overgrowth of small-leaved plants in which the fry can hide. A sufficient amount of natural feed is also required. This will save the kids from the "fish farming" of their parents.

It is better, after all, to "take delivery" in a separate aquarium. Their approximation is determined by the color of the spot at the anal fin and the rectangular shape of the abdomen of the fish. The female partia can eat the offspring, so immediately after the birth it is advisable to move it to the general aquarium.

The number of fry in large specimens can reach 80. It is best to keep them in a separate shallow aerated aquarium. Feed the fry 4-5 times a day with rotifers, cyclops, microworms and periodically substitute a portion of the water for fresh settled. Under these conditions, the offspring grows quickly, has a vigorous, healthy appearance and bright color.

Of particular interest in breeding pesili is the possibility of crossing some of their species with certain types of swordtails. Such a selection is far from being always successful, but the result is more interesting and weightier.

Variety of species

Why are the most characteristic representatives of this genus interesting?

Red platilla

Red platilla - gorgeous fishes of rich red color, their lower fins gleam with bluish shine. For such a color, the poultry needs to be given live food. Moving in layers of water, they immediately attract attention. This is a kind of "Ferrari" of your aquarium. Aquarists often use them in breeding as breeding material to obtain color when breeding petilium of other species.

Disc platilia

Disc platilia - An example of a selection of aquarium fish with a variety of color options. The most common red. In disc plausae, the body shape is completely uncharacteristic for viviparous fish. Its length is almost equal to the height. This species is distinguished by the fact that the male disc partilla is significantly smaller than the female (approximately one and a half times).

Tricolor petilia

Petilia tricolor - one of the most beautiful representatives of the genus. In nature, it is greenish-yellow with a blue tint. As a result of the selection work, the range of colors was significantly expanded. Appeared orange-yellow and black tones. A large beautiful dorsal fin tricolor is also an achievement of breeders. This species can interbreed with the swordtails.

Black platilla

Black petilia - has a mysterious and predatory species, however, like the rest of her relatives, peaceful. Valuable in breeding work makes her the ability to interbreed with the Sword. The offspring of such a cross is obtained with a beautiful bluish or greenish tint.

Of interest is any of the species of these fish. Choose according to your taste, and the partilias will surely revive your 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. Do 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 vysokoplavnichnaya. 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 occurs usually 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.
