Sword-bearer of aquarium fish: content, compatibility, reproduction, photo-video review

POSSIBLE content, compatibility, reproduction, photo-video review

Swordsmen know everything, even those who have never encountered the aquarium world. The Sword bearers gained such fame due to their wide distribution (one can say that they were part of the set of every young aquarist of the former USSR), as well as thanks to a special sign - the tail fin in the form of a sword. Actually, it was for this tail that the Swordtails got their name.

Homeland Sword - Central America (South Mexico and Guatemala). They live in reservoirs with stagnant and slowly running water, thickly overgrown with various aquatic plants.

Swordtails (Xiphophorus helleri) belong to the family of fish. Xiphophorus helleri is translated from Greek as "xiphos" - the sword, "phoros" - carry. The prefix "Helleri" was assigned to swordtails by the name of German naturalist Karl Bartholomeus Geller, who first caught these fish in the Mexican lakes and successfully transported to Europe.

In 1848, these fish were first described by Dr. Johann Jacob Heckel - preparator of the Museum of Natural Sciences at the Imperial Natural History Study of the Museum of Natural Sciences in Vienna.

The body of the fish is elongated and compressed from the sides. The swordtail's mouth is turned up and adapted for taking food from the surface of the water. Fish can reach a size of 10 cm (without a sword). Females are somewhat larger than males; they are similar in shape to all other petilium. In addition to the presence of a "sword" on the lower edge of the caudal fin, the male has gonopodia, an anal fin transformed into the sexual organ.

Compatibility of the Sword

Swordtails are not aggressive. They are compatible with almost all small peaceful fish. Among the best neighbors are tetras, minors, terntions, danios, all fish, etc. They are compatible with almost all bottom fish: corridors, akantoftalmusy, platidorus, antsistrusy, bag-tailed catfish, etc. They get along well with peaceful and not large cichlids, for example, with scalars.

Sword-bearers are not compatible with aggressive and large fish that will hunt them, for example with cichlids (Akara, astronotus, diamond chichasomes, etc.). In addition, it is not recommended to push them to the "veil" fish, because they are slow and swordtails can "pinch" them for fluttering fins.

Males of the Sword show some intolerance and aggression towards each other. Cases of males fights were noted up to causing lethal damage to each other. Therefore, in one aquarium should contain only one male, or several at once (but not a couple!), Plus the same or more females. In this case, the intraspecific aggressiveness of the fish decreases markedly. There are a lot of local conflicts in this case, but their heat is relatively low, and the absolute winner, who would then no longer give anyone a pass, would not be revealed. See article compatibility of aquarium fish.

Life expectancy of the Sword

Life swordtails, by the aquarium standards, medium-long. With good conditions, they can live up to 5 years. Find out how much other fish live HERE!

The minimum volume of the aquarium for the swordmen

Many novice aquarists contain swordtails in small aquariums. However, this is not entirely correct. In fact, the swordtails - it is quite large fish. And taking into account the fact that it is recommended to hold swordsmen in proportion 1 male / 2 or more females, the minimum size of an aquarium for them should be from 50 liters per harem family. Aquarium for the Sword should be wide !!!

About how much you can keep fish in X liters of aquarium, see HERE (at the bottom of the article there are links to aquariums of all volumes).

Requirements for the care and conditions of the swordtails

The Swordtails do not need any special conditions. In fact, the observance of optimal parameters of aquarium water is the key to their well-being. However, do not forget that:

1. Swordtails necessarily need aeration and filtration, a weekly replacement of up to 1/4 of the volume of aquarium water. It is worth noting that these fish do not need a lot of oxygen, and too frequent change (replacement) of aquarium water is not so useful for them as for other types of aquarium fish. Therefore, if you change the water less often, for example, once every 14 days, and not at 7, nothing terrible will happen.

2. The aquarium must be covered with a lid, because the fish are nimble, can jump out and die.

3. Like many fish, swordtails feel comfortable among the living vegetation. As aquarian plants for them are recommended to use valisneria, echinodorus, cryptocoryne, riccia, duckweed and other plants. Creating thickets of plants imitates the natural habitat of fish.

4. At registration of an aquarium it is necessary to organize in it an open space for swimming. Swordtails are great swimmers. Shelters of the Sword are absolutely not needed.

Feeding and Dieting of the Swordsmen

Swordtails unpretentious in food, they are omnivorous and prone to overeating. With pleasure they eat dry and sublimated feeds: flakes, granules, chips. They love live and frozen food (bloodworm, artemia, daphnia, etc.). The food is taken by fish in all layers of aquarium water. Remaining on the surface and fallen to the bottom of the feed also will not remain without attention.

In the diet of the Swordsmen must include vegetable food: flakes or granules with spirulina, special algal tablets. In addition, they willingly eat algae from the walls of the aquarium, plants and decor.

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, 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.

Varieties of aquarium swordtails

The natural natural color of the swordtails is gray-green. However, as a result of selection, a large number of swordtails of various colors and shapes were bred. Unpretentiousness in breeding and the difficulty of crossing led to the presence today more than two dozen of the accepted types of swordtails. Here are some of the most popular:

Bulgarian white swordtails;

High Swordsman;

Mountain Sword;

Green Sword;

Red-speckled tiger swordtails;

Red Sword;

Lemon Sword;

Lyretail Sword;

The sword-bearer of Hell;

Rainbow Swordsmen;

Calico Sword;

Black Swordsman;

Propagation and breeding of the swordtails

Breeding and breeding of the Swordsmen is absolutely simple. It is similar to the reproduction of guppies and other live-beetles And, one might say, actually happens on its own.

Sexual maturity of the Sword comes at the age of 5-6 months. For breeding (and for their own comfort) it is recommended to keep the fish in the proportion of one male to three females. In the process of "grooming" the female, the male performs a kind of mating dance - shuttle movements back and forth.

Fertilization of ripe eggs occurs inside the female. This process can take several days. An interesting feature is that the once fertilized female of the swordtail can produce offspring several more times, even in the absence of a male.

The duration of gestation of the female is 4-6 weeks. This period depends on the parameters of the aquarium water, temperature, lighting and feeding.

A pregnant female has a full belly and has a “black spot of pregnancy” under the tail. It is believed that a few hours before the “birth”, the female's stomach becomes “square”, the female begins to move more actively, “toss” up and down along the aquarium glass.

At one time, the female sweeps from 15 to 100 or more fry. Spawning occurs, as a rule, in the morning.

With abundant nutrition and water temperature 26-27 ° C, childbirth can occur monthly.

Perhaps the most important rule that must be observed when breeding swordsmen is a concern for the survival of young. Unfortunately, the producers eat their own offspring, and given the fact that the fry of the Swordtails are quite large in size and bright in color, this process simply turns into extermination. In nature, the Swordtails never see their offspring, because fry immediately blows over. In an aquarium, parents take fry for food.

To save offspring aquarium densely planted aquarium plants. Plants are located at the bottom of the aquarium, in the water column and especially densely on the surface. Thus, juveniles are provided with shelter "from the evil parents" and the majority of fry survive.

Also, for the safety of offspring, special spouts can be used, which are designed according to the funnel type - the female remains in the funnel, and the swept fry falls out of the funnel into the spawning aquarium. Thus, the absence of contact of the producer and the young is initially ensured.

The third option for preserving offspring is the jigging of producers immediately after spawning. This option is simple, but requires attentiveness and timeliness from the aquarist.

Photos of juveniles, fry of swordtails

After spawning, the female is deposited and provide her with abundant feeding.

The initial food for the young of the swordtails is live dust (nauplii, Artemia, Cyclops, micro-worms, rotifers, shreds).

A week later, the young of the Sword began to weed out - divided into strong and "purebred", and weak and defective destroyed.

Juveniles grow rapidly, after two months the anal fin begins to change in males, and by the third month the "sword" begins to grow.

When keeping different types of swordtails, an independent crossing occurs, as a result of which it is sometimes possible to get beautiful offspring.

An interesting fact from the life of these fish is that a female swordtail can at some moment become a male, i.e. change the floor. This occurs under the conditions of "shortage" of males and is explained by the struggle for the survival of the species. The offspring from the pair of female + former female is almost 90% of female individuals.

Diseases and treatment of swordtails

Swordtails are very resistant fish and can tolerate harsh conditions of detention. However, like all living things, such excellent health does not last forever. The key to successful maintenance of fish is to ensure optimal conditions for aquarium water.

Swordtails are prone to all typical diseases of aquarium fish and there are no nuances in their treatment.

For proper and correct treatment of swordtails, it is necessary to diagnose the disease, and then apply the necessary procedures.

Swordtail aquarium fish: maintenance and care

One of the most popular exotic domestic fish is the old-timer of many aquariums and the favorite of not only experienced, but also beginner aquarists - the swordtail. Xiphophorus Helleri was liked by many breeders for its cheerful disposition, mobility, variety of shapes, types and colors, as well as unpretentiousness to living conditions. Nevertheless, some of the subtleties of the maintenance and care of these fish will not hurt to learn, and this article will help with this.

Central America, South Mexico, Honduras and Guatemala are considered the birthplace of the Sword. These fish have chosen there overgrown reservoirs with slow or standing waters.

In nature, only green swordtails are found, and all aquarium species are bred artificially by breeding and crossing with petillia.

The fishes were brought to Europe by doctor and botanist B.K. Geller They received their name for the xiphoid growth on the caudal fin, which is available only in males (translated from the Greek xiphos - a sword, phoros - bear).


Aquarium swordtails have a body of 5-8 cm, extended in length and compressed from the sides. Their mouths are slightly twisted to make it easier to take food from the surface of the water. The females are larger with noticeable belly and rounded fins, dimmer in color and do not have a sword on the tail fin. With good care, these fish can please owners up to five years, which is considered the average life expectancy.

Originally, the swordtails had only a brownish-olive color with a silver sheen, a pale reddish band along the body and a yellow, red or green sword. But today many varieties of black, lemon, and red have been bred, there are even spotted individuals. Experienced breeders with fins, as a result of which appeared fish with elongated fins and even with two swords.

Behavior in the aquarium

The nature of the swordsmen is peaceful; they, as a rule, do not show aggression towards representatives of similar species. It can be kept in the same container with neons, tetras, minors, ternetias, danios, guppies, mollies, various types of catfish, scalars, etc. It is undesirable to settle with veil fish, as the tails and fins of the latter are at risk of being plucked.

Swordtails should not be placed together with large aggressive fish, such as astronotus, akara, tsikhlazomy and the like.

Within the species, skirmishes and fights can arise between males, especially if there are only two of them in the aquarium. Therefore, experienced aquarists recommend settling at least three male swordsmen at the same time.

How to equip a habitat?

When choosing an aquarium, it is better to dwell on a wide version, with a volume of at least 30 liters. The calculation should be such that three liters of water are needed per fish. The length of the container is recommended not less than 30 cm. A lid or glass is obligatory from above, as the swordtails are very quick and can jump out of the blue.

As for the quality of water, it is better to adhere to the temperature in the range of 18-26 degrees, hardness 8-22 DH, acidity 7-8 pH.

The purity of the water is very important, so it will be useful to install a filter. Regularly (about once a week), you need to replace the water with a third of the volume of the aquarium, before standing for about a day.

For the prevention of diseases of swordsmen, experts recommend for every 10 liters of water to add a tablespoon of sea salt or table salt. But this is not always possible, as it can negatively affect other inhabitants of the aquarium and plants.

Fish do not tolerate the lack of oxygen in the water, so aeration is a prerequisite for their content.

Lighting should be good, but not in direct sunlight.

Soil can take any color and texture.

As for the algae, then for the background it is better to arrange dense thickets of camombs, notched elodeans and the like. At the side of the aquarium they plant small-leaved and long Indian limnofilu, glitter, peristristist. On the surface of the water is good to place Riccia. The foreground should be free space for swimming and feeding.

You can decorate the aquarium with stones, grottoes, snags. But this is not necessary, since the swordsmen do not need shelters.

What to feed?

Unpretentiousness in food - another one of the advantages of these fish. But in order for their growth and development to be the best, nutrition should be diversified and alternated. What can be used?

  1. Dry, live and frozen food (bloodworm, artemia, daphnia, etc.).
  2. Vegetable food, cooked independently (algae, spinach, nettle, lettuce leaves are scalded with boiling water, and then ground).
  3. Non-standard top dressing: boiled egg yolk, crackers, dietary meat, squid or boiled fish. Of course, all you need to grind.

Leftovers should be cleaned so that the water in the aquarium stays clean longer.

About diseases

These fish do not get sick often. The main causes of diseases of the Sword are non-compliance with conditions of detention, colds and infections, trapped with food.

They can suffer fungal diseases that are easily eliminated after quarantine in salted water. It cleans the integuments of harmful bacteria and parasites.

After buying new pets, you need to carefully check them for plaque, cannon, rashes or sores. If any of the above is available, then the fish is sick.

A salt bath (at the rate of one tablespoon of salt per liter of water) with a duration of 15-20 minutes will help to treat the pet and prevent general infection in the aquarium. You can fix the effect of the bath by placing the fish for two days in a weak solution of methylene blue (temperature is about 25 degrees).

For the treatment of diseases of the gills, scales, as well as for infectious individuals, trypaflavin and biomycin are used in solutions.


If the aquarium is overpopulated with female swordtails, they can change their gender to male. At the same time, the xiphoid process grows in them and gonopodia appear on the anal fin. Males do not possess the gift of reincarnation.

Now, having studied the characteristics of keeping and caring for the swordtails, even beginner lovers of these fish will be able to create ideal conditions for their pets.

For those who do not like to read, we offer to watch a video about the contents of the Sword in the aquarium:



Swordsmen know everything, even those who have never encountered the aquarium world. The Sword bearers gained such fame due to their wide distribution (one can say that they were part of the set of every young aquarist of the former USSR), as well as thanks to a special sign - the tail fin in the form of a sword. Actually, it was for this tail that the Swordtails got their name.

Maintenance and care of the swordtails

Contain Swordsmanin in aquariums it is easy enough because of their unpretentiousness to the composition and volume of water. One pair must be at least 6 liters of water. Aquarium needs a long, with a lid (can jump out of the water).

Optimum water parameters: temperature 22-24 ° С, dH 5-20 °, pH 7.0-8.0. Requires strong aeration and filtration. Once a week it is necessary to replace water by 1/3 of the volume. It is recommended to add sea or table salt to water: 1 tbsp. 10 liters of water.

Thick thickets of small-leaved plants (for example, notched elodea, cabomba, wallisneria) are perfect for an aquarium with swordtails. But free space for swimming fish must also be present. On the surface of the water, you can let ricci.

As neighbors fit any peaceful fish. There are conflicts in the group between males of swordtails, so it is necessary that there are more females than males. In this case, the males must be either one or more than three individuals - aggression is sprayed, and not directed directly at each other between the two males.

Breeding swordsmen

Swordtails belong to the family of viviparous. The female at a time is able to give life from 15 to 100 fry, and even more. The number of juveniles born into the world depends on the age and size of the mother, as well as on the conditions of her life. For successful breeding, the pregnant female is deposited in a separate aquarium before birth. So that the fry born to avoid the teeth of an adult female, small-leaved aquatic plants should also be placed there to create life-saving algae thickets in a small pond where it is so good to hide from danger. Breeding will not require any special care from the aquarist.


It will be enough only to isolate the female for the time of childbirth from the rest of the aquarium, and after the childbirth to return her to the familiar environment, leaving the swordtail children to develop independently. By the time of birth, fry are completely formed for the beginning of independent life. As soon as they were born, they immediately begin to tirelessly master the space of the aquarium and actively feed. Kids are almost omnivorous, but it is preferable to give them daphnia and cyclops. With proper feeding, the fry grow rapidly, by 3-4 months they already acquire a “sword”, and puberty occurs in 4-6 months.


Swordtails are not aggressive, peaceful fish. They are compatible with all similar fish: tetras, neons, minors, terntions, danios, all petilium fish: guppies (can bite), mollies, etc. They are compatible with almost all aquarium catfish - corridoratus (speckled catfish), akantoftalmusy, platidor, antsistrusy, bag-tailed catfish, etc. Moreover, the swordtails get along very well with peaceful and not large cichlids, for example, with scalars. It is not recommended to push them to the "veil" fish - they are slow and swordtails can "pinch" them for beautiful, large fins. Not compatible with aggressive and large fish, for example, cichlids: Akara, astronotus, diamond tsikhlazomy

and etc.


What are the diseases and symptoms?

Swordtail Aquarium Fish Diseases There are three main reasons:

  • wrong content;
  • bacterial and fungal infections;
  • parasites.

You would think that only in the first case the fault lies with the aquarist's conscience. But in fact, infections and parasites affect fish with immunocompromised. In other words, even if there is no fungus or parasite in the aquarium, in bad conditions the fish will get sick.

Attentive owner will notice the beginning of the disease Swordtails with daily inspection of aquarium fish. That's what it costs note:

  • fading in place, lying on the bottom;
  • random swimming, rocking, rubbing against stones;
  • loss of appetite;
  • bloating;
  • folding fins;
  • dull and whitish spots on the body;
  • cotton-like shreds.

The diseased individual should be transplanted as soon as possible. It may be possible to save the healthy from infection.

In males, the sword is transparent to 5 mm in length.

Clementia's Sword. Under natural conditions, lives in the Mexican river Sarabia. Fish from 4 to 5.5 cm long, the female is much larger than the male. The body of the fish is of a silver - blue shade with two red longitudinal stripes. The back is painted in olive-beige color, the sword at the male has a yellowish tint with black edging, the length of the sword is about 3.5 cm.

Swordtails: reproduction and maintenance. Aquarium fish swordtails

In every home where there is a child, sooner or later, talking about pets begins. The kid asks the parents several times a day for the bird, the dog, the kitten ... He wants to look after and watch someone, feed the pet, play with him and take him for a walk, show off his new friend to his comrades. But what to do if the apartment is too small for a dog, the papa is allergic to the cat's fur, and the mother simply does not tolerate the piercing sounds made by the parrot?


Great exit - get an aquarium! Hassle with fish at least, and the whole family will receive the aesthetic pleasure to the maximum! In addition, these bright tropical creatures can be admired endlessly. Such contemplation of the home underwater world calms, gives composure and a beneficial effect on the psyche.

Plus, the aquarium will bring a juicy touch to the room's décor, and your child will be looked after by its inhabitants, thus getting used to discipline and responsibility. Moreover, a modern "house" for fish can look like anything! You can easily choose an aquarium so that it harmoniously blends into the overall style of the nursery. Be sure to take the baby with you to the pet store, let him, as an adult, help you choose a tank of the desired shape and size, will find residents for it. In addition to fish, you can buy unhurried snails, a variety of algae, as well as all sorts of paraphernalia - decorative locks and elegantly curled shells. As for the choice of pets themselves, it is better to start with unpretentious species of fish, such as guppies, mollies, danios, barbs, neons ...


For more effeminate scalars, funny shrimps and slow telescopes, if you want, return later. Explain to the child that you first need to learn how to handle simpler fish. Naturally, in any case, it is necessary to consult the seller. He will make sure that predatory and peaceful fish are not in the same “house”; advise food, soil, jewelry, a net; will tell you which compressors, filters and lighting devices are the most convenient to use.

Surely in the list of proposed inhabitants it will be the swordfish fish.

These undemanding small fishes (most often bright red or black in color) with beautiful sharp tails are ideal as the first pets for your kid. Firstly, they do not need special conditions of detention, secondly, they easily get along with other types of fish, and thirdly, they are viviparous. Reproduction of swordtails in an aquarium, it can be said, happens almost by itself. And imagine how much joy the child will have when he sees the first fry that will grow before his eyes!

Reproduction of aquarium fish

So, the choice is made - the swordmen. Their reproduction is a fairly simple process. Fish reach sexual maturity at the age of 6-8 months. The female swordsman is larger, the male is smaller, but only he has the famous long tail in the form of a sword, for which, in fact, this species got its name. Therefore, it is not difficult to distinguish them and understand how many “boys” and “girls” are in the aquarium. It is better to have more females than males. There is one more detail: if there are only two males, they can behave aggressively towards each other and often fight.

Therefore, let him either be alone, or four or more - then their attention is sprayed, and the aquarium swordfish fish will behave much calmer. Consider this nuance when buying them.

Tips for keeping and breeding

To get the offspring, you need to maintain a stable water temperature, make sure that the filter works well, there were areas shaded by algae where the fry can hide. Moreover, it is desirable that the plants were different - and those that are planted in the ground, and those that float on the surface (duckweed, riccia, pistis).

About once a week or as far as evaporation it is necessary to accurately add a certain amount of clean water to the aquarium. Only, God forbid, not from the tap!

At first, it should stand for at least three days, and only then this water can be used. Of course, henceforth the holy duty of the child is to feed the fish in time. Swordtails are eaten mostly with live food, such as bloodworms, pipemaker, daphnia, or cyclops. However, they do not disdain and combined types of food, and pounded oatmeal, and can pinch the algae.

Swordtail aquarium fish will not be lost, even if you decide to leave them for a week, for example, to go on a vacation to the village. They can easily find food at the bottom of the aquarium and its walls, among the pebbles and on the plants. But this does not mean that they can be left to themselves, without looking into the aquarium for 2-3 weeks.

Features of the content of fish

When biological equilibrium is established in the “fish house,” the swordtails get used to each other, their reproduction will take place without outside intervention. One fine day, the child will simply notice that one or even several females noticeably "rounded", became more pot-bellied and sluggish. Explain to him that soon there will be kids in the fish. There will be joy!

Pregnancy lasts about a month and a half, and after this time a whole flock of fry is born. They can be as much as 15-20 pieces, and much more, sometimes the number reaches as much as one hundred. These are fully formed fish, only small and translucent. They independently swim, eat, possess an instinct of self-preservation - they hide in the branches of algae, swim under decorative ornaments. However, if you want to save all the fry, at first they still need to create special conditions. So, a pregnant female shortly before birth is better to be separated from other inhabitants of the underwater world.

Important note

A small aquarium or even a regular glass liter jar, washed with baking soda, is suitable for this purpose. There you need to pour part of the separated water and part of the water from the aquarium, plant a couple of plants. It is desirable that the algae were small-leaved and of both types - ground and floating, then it will be easier for newborns to hide in them. Let the child carefully, with a special net, catch the future mother and quickly launch into the prepared temporary shelter.

After the offspring is safely born, the female needs to be returned back to the aquarium, since with its sharp teeth it can destroy unwary fry. It is better to feed newborns with cyclops and daphnia. When the fish in the bank grow up a little, they can be shared with the rest of their relatives.

Interesting feature

In fish such as swordtails, reproduction under favorable conditions - a stable water temperature, good lighting, live food - can occur every month. Fry quickly turn into mature individuals. So, already in 3-4 months, the males will acquire a sword tail, and in a couple of months, full-fledged adult swordsmen will swim in the aquarium. Fish breeding will begin on a new one ... However, if pregnant females are not relocated to another tank, the law of nature, such as natural selection, will act, during which not all fry will survive, but only the most nimble and nimble.

Small conclusion

Here they are unpretentious, swordfish fish. Reproducing them, as you already understood, practically does not need any correction, and if you give them free will, the inhabitants of your underwater world will breed to such an extent that it will be possible to bestow fry on all their friends and relatives.

The red swordtail is a small aquarium fish that lives in the waters of Central America. Also, these fish are found in turbulent rivers, lagoons and marshes.

The red swordtail is the result of the crossing of the red petilia and the green swordtail. They are considered the first type of Sword. These fish have no special requirements for the content, like a large space and floating algae. Fodder prefer live, vegetable. A 70-80 liter aquarium will be a very comfortable habitat for them. Such fish must have fresh and clean water. The temperature of the content is not lower than 26 degrees.

Red swordtails - viviparous fish. In males during puberty, the anal fin is lengthened and sharpened, acquiring the appearance of a sharp sword. In fact, this sword is a collective body, which has a name - gonopody. The females of the red sword of the sword do not have: on this basis, and distinguish the sex of animals.

To obtain offspring, these fishes lack one fertilization, since the "sacks" with sperm enter the female's body and are stored there for several months. It is enough to fertilize the female of the red swordtail only once, in order to get offspring for a long time.

There is one more interesting fact: after some time the swordtail females have the ability to turn into a male. The females that have become males do not have the ability to bring posterity But after its change, the female, turned into a male, can be distinguished from the male. Such a fish retains a typical body shape, fins are less developed.

The swordtail chooses only the best males to mate. At this point they are from 7 months and they are 6-8 cm long (length without a sword). Such a male should be slim, active, have an interesting color and the longest sword. Females choose the most productive of the offspring. Swordtail fish can carry offspring for 4-6 weeks. The female before spawning is deposited in a separate place, as the males of the swordtails exterminate the boys (as you know, the females bring about 200 of them), the size of which is from 8 to 10 millimeters. In the general aquarium the female is deposited after giving birth, but without the babies. The formation of the floor occurs depending on the temperature of the water. Born fry actively swim and feed, as they are born mature. Their diet should contain a large amount of protein.

With a good and stable water temperature, females spawn fry monthly. They will not need a male for many months. A female should be larger than a male.

Approximately once every two months, the fish must be sorted by size, as they grow unevenly. The Sword-bearer is a peace-loving fish, therefore it must be maintained with the same peace-loving fish, in order to avoid trouble. It is not advisable to sit down swordtails to slow-moving fish, because of their activity, they can tear off fins.

It is necessary to closely monitor the health of the fish. Pets will suffer if elemental conditions of detention are violated, as well as in the event of infection caused by feed.

Aquarium fish swordtails

The natural color of these fish is considered to be green. But today there are a lot of various selection species with the most different shades. There is one significant difference between the sexes: the lower rays of the caudal fin in males are noticeably elongated, thereby acquiring the appearance of a sword. Depending on the species, the body length of the fish ranges from 5 to 8 cm.

Types of Sword

Different colors of swordfish aquarium fish were obtained by crossing. In addition to different colors, representatives of different species have different fin shapes. Here are the main types of swordtails who breed at home in aquariums:

  1. Green Swordsman. Its color is olive brown, fairly light. Along the entire body is a bright strip of red. The body is slightly flattened, rather narrow.
  2. Red Swordsman. This species was obtained by crossing a green swordtail and a red pelicion. The body of the fish has a bright red hue.
  3. White swordtail This is a pronounced albinistic form. The fish has bright red eyes. This species is more stable and strong in terms of constitution than the rest.
  4. Brindle. On the red body of the fish there are black stripes resembling the color of a tiger's skin. The tail is quite long, black.
  5. Mountain Sword. Color creamy yellow. On the sides are visible small stripes in the form of zigzags, there are small specks.
  6. The black. The species was obtained by crossing a green swordtail and a black pellition. The color may be greenish or blue reflux.

Care of Swordsmen

When choosing an aquarium, first note its length. Aquarium fish swordtails need a long aquarium, preferably with vegetation reaching the surface of the water. In general, the vegetation in the aquarium with the swordtails is a prerequisite for their successful maintenance.

These fish are omnivores, and therefore there will be no problems with feeding. A bloodworm or any dry prepared feed will do. It is advisable not to give preference to only one type of feed, it is better to diversify the nutrition of the fish.

The fishes are peaceful, so feel free to add all kinds of calm and docile fish. Males are pretty bullies. In order to avoid problems, try to hook up at the same time no more than three individuals of different species, ideally, the males should belong to the same species.

Female swordwoman

As a rule, the size of the female swordtail does not exceed 8 cm. It has a rounded tail fin, the xiphoid process is absent. The color of the female is always much paler than that of the male.

Depending on the conditions of detention, female puberty begins at the age of 6-8 months. To determine the moment when the female is ready to bear the offspring, you can do the following: inspect the anal fin, if you can clearly see the birthing spot, feel free to start breeding fish.

Viviparous fishes, and therefore fertilization occurs naturally. From each fertilization can be expected 2-4 litters. Pregnancy lasts 4 to 6 weeks. The female is able to sweep up to 200 fry, it depends on the type of fish, size and heredity.

Care for Swordbone Fry

Swordsmen fry requires a little more careful care than adult fish:

  1. Prepare a separate aquarium for the pregnant fish in advance. As soon as the babies are born, otsadite it. The fact is that fry will be at risk from other inhabitants of the aquarium.
  2. For fry it is necessary to plant small-leaved algae in the aquarium so that they can hide.
  3. Fry can eat dry or live food. On the second day try to give pounded egg yolk. Offer dry daphnia. Very willingly they eat bred artemia.
  4. If the temperature in the aquarium is about 30 ° C, you will get more males, at a low temperature - females.
