Aquarium fish swordtail
The sword-bearer (Latin Xiphophorus hellerii) is one of the most popular and unpretentious fish in the aquarium. The first swordtails appeared in aquariums back in 1864, and since then have not lost their popularity. The long outgrowth on the lower fin in males, like a sword, gave it a name. But not only for this they love the Swordsman - he is unpretentious, handsome, very diverse in color and easily reproduces.
Swordtails in general are quite peaceful fish, well suited for general aquariums. But, they have very different characters, and he can be both a quiet and timid, and a cocky bully. Especially males can be aggressive towards each other.
Swordtails are best kept in aquariums with lots of plants and free swimming. Floating plants will create diffused light and provide shelter for fry. Like many live beetles, swordtails can live in brackish water, but this is not necessary.
Habitat in nature
The birthplace of fish in Central America from southern Mexico to Guatemala. There are several colors of the original Xiphophorous helleri swordtail, which are much paler than the aquarium and breeding forms.
They live in nature in various reservoirs, both with flowing and stagnant water. They prefer shallow, abundantly overgrown places where they feed on various insects, algae and detritus.
Swordtails can grow quite large, males up to 11 cm, and females up to 12. But, usually in aquariums they are smaller, it is very dependent on the type and conditions of detention. They live in an aquarium from 3 to 5 years.
As for coloring, it is difficult to single out any one form, although the most popular will be red with a black tail. And so they are red, green, black, albino, stained, yellow. To describe them all is quite a difficult task. But, anyone who has ever seen an aquarium represents what a swordtail looks like. So this fish is common.
One of the most popular fish among beginner aquarists. Unpretentious, not too big, just divorced. The disadvantages include the pugnacity of some males, especially among themselves.
Feeding the Sword
You can feed them with cereal, live or frozen food, and other feed for aquarium fish. Like all fish, swordtails need a varied diet. It is especially important to feed them with plant foods that are high in fiber. The fact is that in nature, thin and fragile algae constitute a large part of the diet of the Swordsmen and other fouling. In an aquarium, this amount of algae will be superfluous, but you can always buy flakes with a plant component. You can make these flakes the basis of the diet, and live food additional nutrition. Live food can be given any, swordtails completely unpretentious.
Maintenance and care in the aquarium
Swordtails are very unpretentious in content. In an aquarium with a volume of 35 liters you can keep one of the swordtails, but this is a very active fish and the more volume there is, the better. Remember that for breeding you need to contain one male and 2-3 females, if there is 1 male and 1 female, then the male can drive her to death. And try not to buy several males in one aquarium, as the hierarchy of the swordsmen is pronounced. The main male will always drive the rest, and this is fights, injuries, disorder.
Swordtails are quite unpretentious when it comes to temperature and can live both at 18C and at 28C. The ideal would be 23-25C. Parameters such as hardness and pH are not very important for them, but they feel better in water of medium hardness and at pH 6.8-7.8.
It is desirable that the aquarium was filtering, it is quite enough and the internal filter. Required water changes to fresh, about 20% weekly. But note that besides the swordtail swims very fast, it also jumps well. The aquarium must be covered, otherwise you risk finding a dried corpse.
How to decorate the aquarium - to your taste. The only thing that is desirable is that it would be densely planted with plants, since the swordtails love such aquariums, and it is easier to hide in the bushes from the aggression of the males.
Compatible with other fish
Old males can attack other fish, but here it depends on the particular individual. Some live quite peacefully themselves, and some become violent. Aggression is promoted by close aquariums without plants. What you don’t need to do exactly is to keep two or more males in the same aquarium. This leads to guaranteed fights. Who do they get along with? With viviparous: guppies, specials, mollies. Well get along with a variety of bloomers: angelfish, gourami, neon, iris. But with gold, it is better not to contain them ... Gold needs more cold water, and swords are restless neighbors.
It is extremely easy to distinguish a male from a female from a swordtail. Only the male on the tail fin has a sword, a long outgrowth for which the fish got its name. Also, all viviparous, anal fin of the male is pointed and narrow (gonopodia), and females wide.
Quite often it happens that the female swordtail suddenly grows his sword and becomes a male! However, she behaves like a male, cares for other females, but is barren. The reasons for this phenomenon are unclear.
Propagation of the Sword
Swordtails - viviparous fish, that is, the fry they appear not in the form of an egg, but fully formed. The male fertilizes the eggs inside the body of the female, and she carries them to full maturity. Usually this period lasts 28-30 days. Actually breeding Swordsmen at home is not easy, but elementary. The young male is constantly active and pursues the female, in fact, all you need to do is to take her away regularly.
As for other viviparous (guppies, mollies), it is very easy to get fry from the swordsmen. The female can even give birth to fry without a male, the fact is that she can keep the male's milk in a frozen state and fertilize themselves with them ... So if suddenly the female gave birth to fry and there is no male in the aquarium, this is exactly the case that worked.
The female gives birth:
Sword bearers of spores for reproduction and sometimes the only thing that needs to be done is to raise the temperature in the aquarium to 25-27С. The level of ammonia and nitrates at the same time should be kept as low as possible, and pH 6.8-7.8.
When the female gets full, watch the dark spot near her anus. When it darkens and the female recovers significantly, it means time for giving birth soon. This is a dark spot, in fact, the eyes of the formed fry, which shine through her body. You can leave the female in an aquarium, but the fry will survive very little, since other swordtails are very active in eating it.
If you want to survive as many swordsman fry as possible, it is better to transplant the female. Whichever option is chosen, the main thing is that in the aquarium there were a lot of thick bushes. The fact is that childbirth of the swordtails gives birth best of all in such thickets.
The fry of the swordtails are large, active and hungry. What to feed the swordfish fry? You can feed the egg yolk, finely grated flakes and naupililiy Artemia. It is better to add spirulina or flakes with fiber in the diet. The combination of spriulin + live food and your fry will grow very fast and bright.
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.
Class: Ray fish
Conditions in the aquarium:
Water temperature: 22 - 26 ° C.
(tolerates a temporary decrease in temperature to 15 ° C)
"Acidity" Ph: 7,0 - 7,5.
Stiffness dH: 6-20°
Aggressiveness: not aggressive 10%
The complexity of the content: easy
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 is markedly reduced. 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;
Red-speckled tiger swordtails;
The sword-bearer of Hell;
All kinds of swordtails with photos HERE.
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 provided.
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.Photo "pregnant" female of the swordtail, or rather born out
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.

HECKERS - AQUARIUM FISHES.
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.
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.
COMPATIBILITY OF AQUARIUM FISHES
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, baggy-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.DISEASES OF SURFACERS
What are the diseases and symptoms?
Swordtail Aquarium Fish Diseases There are three main reasons:
- wrong content;
- bacterial and fungal infections;
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;
- 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.

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 take care of 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.
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.
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.
Here they are unpretentious, swordfish fish. Reproducing them, as you already understood, practically does not need any correction, and, if you give them free rein, the inhabitants of your underwater world will breed to such an extent that it will be possible to bestow fry on all their acquaintances and relatives. We wish you success in their breeding!
Aquarium fish swordtails: reproduction and maintenance
Swordtails are very popular among professional aquarists, and among fans. But before you get these bright fish, it is better to find out the details of care, breeding, compatibility with other types of fish, etc.
The natural habitat of the swordtails is Central America and South Mexico. Such an interesting name was given to these fish because of the unique shape of the fin. It is only for males and is used by them for reproduction. Surprisingly, females of the swordtail can change their gender by growing a sword fin, and even in such a state give birth to offspring. In length, they are from 8 to 12 cm, not counting, of course, its fin. Swordtails live about 4-5 years.
Swordtails - aquarium fish: species
The natural swordtail is usually green, all other multi-colored fish are hybrids bred artificially. Varieties of swordtails:
- high altitude;
- Bulgarian white;
- red-speckled tiger;
- the black.
Aquarium for fish
Swordtails do not require any thorough care. This way they are easy to maintain. They do not need a special composition or a certain amount of water, they withstand a good lowering of the temperature (the optimum water temperature for them is 23-25 ° C). Water hardness also does not become a problem for these fish - 8-25. Acidity is acceptable within 7-8.
To equip an aquarium, you first need to figure out what shape it will be. It is better to take a rectangular aquarium without any decorations, which only interfere.
As for the volume, then for two representatives of this species or fish of similar size, an average of 8–10 liters of water is needed, that is, 10–15 individuals per capacity of 50 liters.
Install the aquarium should be closer to the window, because the light is needed and the fish themselves, and plants. But putting it on the windowsill is a bad idea, because the sun or the heat of the battery will overheat the water and it will bloom.
The surface must be flat, otherwise the walls of the aquarium may burst (if this happened, the article “Repair the aquarium at home” will help to correct the situation).
It is better when there are plants in the tank, then you can not be afraid to leave your pets without food in rare cases. Aquarium plants should be selected as thick as possible so that the fry can hide from more adult individuals. But there should be a space for the free movement of fish. To do this, fit, gloss and glossy cabomba.
At least once a week, it is recommended to replace 20-30% of the aquarium water with clean water, and you can also add sea salt to it.
As the soil for the aquarium, you can take the usual pebbles. Aeration of water is desirable, but not necessary, at a low density of fish population.
As for food, here too the swordtails are universal - any food, live or dry, is suitable for them. It is recommended not to forget about vegetable types of feed, and to use them in addition to algae. For this fit variety of lettuce, spinach or oatmeal.
Having decided to start these fish, you need to remember the so-called hierarchy, and therefore it is better to place more females in one aquarium. There will be enough males and a few, preferably 3-4, so that between them there is no particular competition.You should always cover the aquarium with something from above, as the swordtails are very nimble and like to jump out of it.
Aquarium fish swordtails: compatibility with other species
These are, in general, fairly calm fish; they only sort out relationships with each other, so you can keep them in the same container with other species. The only thing that they can aggressively treat smaller fish.
Barbs, cockerels, discus, tetra, labo, guppy, gourami get along well with swordtails.
Not very successful combination with them are eels and shrimps, but cichlids, goldfish and astronotuses are completely incompatible with swordtails.
For mating, the choice of the female falls on the most active and brightly colored male, that is, on the most productive. The more his fin, the better. In females it is an internal fertilization, therefore it brings fry several more times without the participation of the male.
Carrying fry lasts about 40 days, and their number is always different. This number ranges from 150 fry per pregnancy, but sometimes more.
At the time of gestation, the female individual is taken from the rest of the fish and transplanted into a small container of 20 liters. You also need to constantly monitor that after birth, she did not touch the babies, it is better to leave them alone, and return the mother to the aquarium.
Fry quickly form and swim almost immediately and eat well. For the normal development of children need to feed them as often as possible. You can use, for example, artemia, microcores, or shredded tubers.
Each individual develops differently, so from time to time it is necessary to select grown-up fish from still small ones and replant them separately. Once fish reach 4-5 months, they can be considered adults and are capable of breeding.
Before the acquisition is recommended to check the fish for infections. Need to pay close attention to the rash, fluff or sores. If something like this is present on the body of the fish, then it is sick.Even with full confidence in the purchase of healthy swordtails, just in case, they should be left for 10-15 minutes in a container with salt water, and then transplanted into an aquarium.
With a clear disease of the fish, for example, the appearance of white fluff, it is placed first in a salted bath, then a weak solution of methylene blue is made and the swordtail is kept in it for 2-3 days. The temperature of this fluid must be at least 24 ° C. Tripapaflavin and biomitsin help in infections and diseases of the gills.
It is interesting and very exciting to keep and breed the Swordsmen. For example, you can cross fish of different breeds and get unique fry with new coloring or fins. And even a child can cope with elementary ways of caring for them.

Aquarium Warriors - Swordtails
The Sword-bearer (Latin Xiphophorus hellerii) is a freshwater fish of the Petsilievye family. The first aquarium fish, the swordtail, appeared in the houses of Europeans in the middle of the 19th century. Thanks to endurance, unpretentiousness and simplicity of the maintenance, the swordtail is still popular as a pet.
These fish are from Central America, are found in the waters of Honduras, Mexico and Guatemala. Wild swordtails are characterized by a faded color compared to aquarium rocks. Xiphophorus hellerii can live both in flowing and still water, in places where there is a lot of algae and insects.
Xiphophorus hellerii looks relatively large - the male has a body size of 10-11 cm, the female is larger - 12 cm, the aquarium representatives are slightly smaller. Lifespan in captivity: 3-5 years. The color of the body can be different - wild specimens have shiny olive-yellow scales, males have a long tail. Red, green, yellow, spotted, black - each of these Swordsmen can be found in home aquariums.
Sexual dimorphism is expressed: on the caudal fin of the female there is no long lower ray in the form of a “sword,” the male has it. The male has a coiled anal fin (gonopodia). The female has anal fin rounded and wide. Due to the lack of sex chromosomes, sometimes swordtails can change the sex - females grow the lower tail ray, and care for other females.
Watch a useful video about the contents of the Sword.
The maintenance and care of the swordtail will not give labor to the novice amateur enthusiast. 35-50 liters of water are required for one fish, therefore it is better to settle several fish in a spacious tank. In the same area should be no more than one male, and several females. Males Xiphophorus hellerii have an aggressive disposition, especially in a close aquarium.
Suitable parameters of the aquatic environment at which the content of fish is possible: temperature: 22-26 ° C, acidity 6.5-7.5 pH, hardness - average from 5 to 15 °. A complete care can provide filtration using an internal filter, the weekly replacement of 20% of water with fresh and clean. Be sure to close the tank cover - the swordtails are very active and bouncy.
For scenery, tall plants with small or wide leaves are suitable: elodea, cryptocoryne, anubias, echinodorus, arrowhead, wallisneria and others. Sand or pebbles are suitable as soil. Install many shelters in the tank so that the females can hide from the aggression of the male.
The content of several male swordtails will create constant competition, so they are incompatible as neighbors. And so the Swordtails get along well with proportionate, peace-loving species of fish. Care for the swordtails in an aquarium can be simple if there are other viviparous species living in it: guppies, petilles, mollies. The content is also allowed with bird species: iris, gourah, minors, ternets, tetras.
Feeding should be varied: give us food live, frozen, dry and vegetable food. In the natural environment, swordtails eat plants and algae, so the fiber content in the diet is an important component of good nutrition. Xiphophorus hellerii eat bloodworm, tubule, koretra, cyclop, daphnia, artemia, insect larvae, lettuce and spinach, feed with spirulina. You can also give sinking granules, branded flakes production.
Look at the flock of Swordsmen.
The red swordtail is a hybrid form of the green swordtail and red plagus. It is characterized by a bright shade of scales, the red pigment has turned out as a result of strict selection of adult individuals. Fish care is simple, it easily adapts to the general aquarium. Water temperature for content: 22–25 ° C, pH 6.5–7.5 pH, medium hardness.
The green swordtail is a beautiful aquarium fish that was brought in from Central America. The body is elongated, narrow, flattened on the sides. The color of scales is olive-brown, or grayish-yellow with green tint. A horizontal strip of violet hue passes through the body, parallel to it are 2 more narrow stripes. Brown splashes are visible on the dorsal fin, the male sword on the tail shimmers in a green, blue color. A pure green swordtail can only be found in nature; today it has become the material for creating many hybrid breeds. The content of the fish is also simple - it is perfectly acclimatized in captivity.
The black swordtail is a descendant of the green swordtail and black plagus. The body of the body is long and narrow, the color of the scales is velvety black, it shimmers with a blue tint. Silver eyes with dark pupil. Breeding of this breed is quite problematic, since the female can become ill with melanosis - excessive pigmentation of the skin. Sometimes the female may be infertile, so breeding is likely with proper water parameters. To avoid the degeneration of the breed, females can not be crossed with males of other breeds. Beautiful specimens are obtained with the standard crossing of the green swordtail and the black plaza.
Calico swordtail - got its name due to the triple color of scales. On a white background scattered black and red blotches. Breeding is also problematic - to display calico color is quite difficult. Nowadays, aquarium lovers try to use the breed of placium and "mechikov" for optimal results, but so far this has not been possible.
The rainbow Xiphophorus hellerii is a hybrid breed obtained by crossing white Bulgarian Bulgarian swordsmen. The color of the scales is gray-green, with an orange tinge, red-brown stripes are seen on it. The fins are painted in a red-orange tone.
Tiger red-speckled Xiphophorus hellerii - the breed was bred in the 40s of the twentieth century in Moscow. The color of the scales is ruby, there are black spots on it. The lower rays of the tail are long, melanosis is rare. When breeding a breed, it is advisable not to choose fish with pure black tail fins and a black part of the tailpiece.
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 veils, as the tails and fins of the latter risk 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.
Декорировать аквариум можно камнями, гротами, корягами. Но это необязательно, так как укрытия меченосцам не нужны.
What to feed?
Неприхотливость в еде - еще один из плюсов этих рыбок. Но чтобы рост и развитие их были наилучшими, питание стоит разнообразить и чередовать. Что можно использовать?
- Dry, live and frozen food (bloodworm, artemia, daphnia, etc.).
- Vegetable food, cooked independently (algae, spinach, nettle, lettuce leaves are scalded with boiling water, and then ground).
- 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.
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:
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. Females that have become males do not have the ability to produce offspring. 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.

How to care for swordfish fish
The swordfish aquarium fish belongs to the order of carnelians, petsilid family. In nature, such fish can be found in the waters of Guatemala, Central America, Mexico and Honduras. Before you get the swordtails for your aquarium, you need to familiarize yourself with the rules of their maintenance and nutrition.
The question "opened a pet shop. Business is not going. What to do?" - 2 answers
Description of the Swordsmen
The body length of males reaches 8 centimeters, females - 12 centimeters, it all depends on the conditions of the Sword. A characteristic feature of the Sword is a peculiar process on the lower part of the caudal fin, which resembles a sword in appearance. Often there are hybrids with a pair of swords, as well as an enlarged dorsal fin. Females have a less bright color. The anal fin of the male is transformed into gonopodia - the genital for reproduction. Swordtails peacefully relate to other species of fish, get along well with them in the same aquarium. Female swordsmen should be more than males. A strong male often pursues a weaker one.
The contents of the swordtails
Swordtails are not demanding conditions of detention. The most optimal water temperature in the aquarium is 24-26 degrees. Fish easily tolerates a temporary decrease in water temperature to 16 degrees. Stiffness can vary in a large range - 8-25 dH, but it is recommended to maintain the acidity in the range of 7-8 pH. At least once a week, replace one-third of the volume of water in the aquarium, it is advisable to periodically produce enrichment of water with oxygen.
Plant the aquarium with small-leaved plants that form dense thickets (Toothed elodiea, Cabomba or Vallisneria). Fry will have the opportunity to hide in them from adult fish. Let the moss - richchia, which forms the picturesque islands, open on the surface of the water. Swordtails - very active fish, they sometimes so frolic that they can jump out of the aquarium. To avoid this, cover the aquarium with a lid.
The life of the Sword, however, like other species of fish, depends on proper and complete nutrition. They are completely unpretentious in food. The optimal diet should include plant and live food: pipe, artemia, daphnia, spinach, algae, various varieties of lettuce, bloodworm, cyclop, mosquito larvae, crushed oatmeal, peas and nettle. You can use any food, either live or canned, dry or frozen.
If you need to go on vacation or a business trip, you do not need to worry, as the aquarium swordtails easily tolerate the lack of food for one to two weeks without harming their health. Fish feed on various algal fouling that forms on aquarium glass or plant leaves.
Swordtails belong to the group of viviparous, they give birth to fully formed and large fry. Bearing lasts about forty days, before giving birth, the female's abdomen increases, becomes square. Place the female in a separate container with a large number of small-leaved plants. After birth, return it back to the general aquarium. Starter feed for fry: artemia, nematodes, chopped tubule, egg yolk, industrial feed.
Golden Swordtail Fish: Content
The Golden Sword is a fish living in Central and North America (Veracruz, Mexico, Honduras, Guatemala). It prefers river sources, high-altitude water bodies, swamps, lagoons and ponds. The duration of its life in natural conditions ranges from three to five years.
How does a golden swordtail behave and behave in an aquarium?
As with all fish of the genus Poticilia, the golden swordtail has a body extended in length, slightly compressed from the sides. Males are slimmer and smaller than females; they can be as long as eight centimeters (without a sword). Females usually grow up to twelve centimeters. The mouth of the fish is slightly turned up, adapted for feeding from the surface of the water.
In small flocks, as a rule, a hierarchy is established between the individuals. For this reason, it is necessary to contain either one male and several females, or two to three males and six to nine females. Otherwise, a strong golden sword may slaughter a weaker one. In relation to other species of aquarium fish, the swordtail does not show aggression, but it is worth considering that it can damage the long fins that some species of fish have (for example, guppy voilevye).
Golden Swordsmen: content
Above the aquarium should be closed with a lid, as the swordtail can jump out of it. The dimensions of the walls of the water home should be at least thirty centimeters. One pair of fish should have at least six liters of water. It is also necessary to provide strong aeration and good filtration; water should be replaced by thirty percent once a week.
In addition, add salt or salt to the aquarium (1 tbsp per 10 liters of water). Water temperature - from 20 to 25 degrees; if necessary, swordtails can briefly endure lower temperatures (up to 10 degrees). In the aquarium, you can plant dense thickets and / or floating plants. However, it is worth remembering that the swordtails need free space for swimming.
What eats swordfish-fish?
This species of fish feeds on some animals (cyclop, artemia, bloodworm, daphnia, mosquito larvae, tubers) and plants (lettuce, algae, nettle leaves and spinach, peas). If only golden swordtails live in an aquarium, then all the uneaten food is removed after about five minutes so that it does not spoil the water.
Golden swordfish - a beautiful fish, peaceful and mobile. With proper care and full content, it will delight its owner for many years!
Propagation of the Sword in Captivity
The breeding of the Sword is one of the main issues that bother novice aquarists. However, it is easy to solve, since breeding of the swordtails is possible both in the general aquarium and in a separate spawning ground. In order for reproduction to turn out to be fast and correct at home, such moments should be taken into account:
- Creation of proper conditions for producers;
- Proper spawning organization;
- Quality care for the fish.
How to create optimal conditions for reproduction?
Swordtails are viviparous fishes that produce fry ready for a full life. They become sexually mature at the age of 6-8 months, some specimens may be ready for reproduction at the age of 3 months. To reproduce succeeded, you need to pay special attention to the diet of future producers. Protein food will allow you to produce as many healthy fry as possible.
The optimal feeding base for adult males and females is live and vegetable food. A few weeks before breeding, feed the fish with daphnia, cyclops, coregetra, artemia and bloodworms. Food with spirulina, spinach and lettuce leaves, dandelion leaves, and soft cereals (rice, millet, oatmeal without salt) are suitable from vegetable food. To saturate the aquarium with algae food is not necessary so that the water is not enriched with ammonia and nitrates.
See how to breed Swordsmen.
Reproduction can stimulate the substitution of water, as well as increasing its temperature by several degrees. Provide filtration in the aquarium with an internal filter, and aeration. Pure water saturated with oxygen will stimulate the mating of fish. Once a week make a replacement of 25% of water for fresh and clean.
Swordtails, the reproduction of which will take place not in the spawning grounds, but in conditions of a common aquarium, should get used to the gradual increase in water temperature. The temperature regime should be set at 26-28 ° C, raising it for 5-7 days. The acidity of aquarium water is allowed at pH 7.0-8.0, the hardness - 10-12 dH. The number of females and males in the brood depends on the water temperature. In water with a temperature below 24 degrees there will be more females, above 25-25 degrees - males. Similar water parameters should be in spawning. In order for producers not to experience shock when moving to such a reservoir, the same parameters of the environment should be in a permanent aquarium and spawning grounds.
Preparation of fish and spawning for breeding
In order for the offspring to be beautiful and healthy, it is necessary to choose the right males and females for spawning. The age of males should be 8 months, their tail fin should stand out with a long lower ray, and gonopodia should increase in size. The female should be 8-10 months old, large in size and have a rounded abdomen, which indicates readiness for reproduction.
Fertilization of the fish swordtail intrauterine. If fertilization has occurred, part of the male spermatozoa will remain in the female's abdomen, which will fertilize the female again, without the participation of the male individual. Therefore, having gotten the Sword-bearers, you should know that these fish can produce offspring every month. In one spawning, the female sword bearer will give birth to 50-200 fry.
Why exactly this amount? The fact is that young females bring less offspring, mature ones more, and with each birth the number of fry will increase. Also, the number of calves depends on the species, the conditions of the fish. Pregnancy lasts 4-6 weeks; in the female, the belly will become round, before giving birth it will become almost square in shape. A month before giving birth you need to prepare a spawn.
As a spawning tank suitable capacity of 25-50 liters with infused tap water. It is recommended to plant small-leaved vegetation in the bottom of the tank, in which fry will be hidden. After preparing the spawning grounds, a female is fed into it, which is fed with live food. After the birth of the young, the female fish is deposited in a common aquarium so that she does not eat her brood. For delicate felling, use a net.
See how the swordtail fry are born.
Can swordtails change their gender?
Swordtails are special viviparous fishes that are capable of changing sex throughout life. This feature is due to the absence of sex chromosomes. Newborn swordtails do not have obvious sex characteristics, only at the age of 3-6 months they will be noticeable. Some fry breed at the age of 3-4 months, so they should be sorted by gender - females and males should be settled in separate containers.
During the life of the female swordtail can become a male, and vice versa. Such metamorphoses are inherent in those individuals who are trying to preserve the species in the face of the threat of extinction of the pack. In one aquarium can live 1 male and 2-3 females. With the passage of time, the male may die, and one of the females will begin to turn into a male. It forms gonopodium, lengthens the lower ray of the caudal fin. When the fish that have changed their sex from female to male reproduce, their descendants will be female.
You can adjust the sex of the fry of the future pets. If you want to breed males or females for sale, the water temperature must be raised or lowered by several degrees. Avoid early crossing of fry, they are ready for it at an early age. When species are crossed, beautiful offspring can turn out; when breeding breeds are crossed, degeneration will occur.
