Swordfish Aquarium Fish

maintenance, care, compatibility

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.

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.

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.

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.

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

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 swordtails, by the aquarium standards, medium-long. With good conditions, they can live up to 5 years.

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 excellent swimmers.

Shelters of the Sword are absolutely not needed.

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;

Lyre-tailed Sword;

The sword-bearer of Hell;

Rainbow Swordsmen;

Calico Swordsman;

Black Swordsman;

All kinds of swordtails with photos HERE.

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 “courtship” for 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.

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.

Viviparous aquarium fish. Guide to keeping and breeding

Livebreeding Fishes Author: Peter W. Scott Languages: Russian Publisher: Phoenix

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).

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.

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.

Swordtails belong to the family of viviparous, carp-toothed. The body is elongated, flattened laterally.

The natural background color of the males is light brownish-olive, on the back with a green tint. A red two-millimeter strip runs along the sides, and two narrower red stripes below and above it. The long lower ray of the tail fin (sword) has a black clear edging.

The color of the female is much paler, the body with a silvery sheen, the middle of the body is occupied by a wide strip, and below and above this strip pass two more narrow strips 0.5 mm wide.

As a result of breeding, the Sword-bearers have not only various forms of fins, but also different colors of their body colors: black, red, olive, orange, yellow, and their combinations (for example, yellow body and black fins). Sword-bearers with two swords are also drawn at the bottom and the top of the tail.

The body of a male (without a sword) can grow up to 8 cm, and females up to 12 cm.

Swordtails live up to three to five years.

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.

Swordtails: reproduction and maintenance. Aquarium fish swordtails

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 ensure 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!

Aquarium fish swordtails: reproduction and maintenance

The natural swordtail is usually green, all other multi-colored fish are hybrids bred artificially. Varieties of swordtails:

  • mountain;
  • high altitude;
  • green;
  • Bulgarian white;
  • citric;
  • red;
  • lyrebird;
  • red-speckled tiger;
  • Ada;
  • calico;
  • rainbow;
  • the black.

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 arrange the aquarium, you first need to find out what form 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

How to care for swordfish fish :: aquarium swordfish fish :: Aquarium 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 store. Business is not going. What to do? “- 2 answers


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.


Swordtails are not demanding of conditions. 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.

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:

  • Creating appropriate conditions for manufacturers;
  • Proper spawning organization;
  • Quality care for the fish.

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.


In order for the offspring to turn out beautiful and healthy, it is necessary to choose 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.

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.

All lovers of aquarium fish is known for this kind of swordtail. It is impossible to confuse with anyone. The main feature of pets is the xiphoid process of the lower part of the tail.

It occurs predominantly in males, but sometimes it occurs in females.

This species is considered the most unpretentious in keeping and breeding, and therefore these animals are advised to acquire novice aquarists. It is believed that the swordtails – peace-loving fish, and can cohabit with other species of fish. If several males of Swordtails live in an aquarium, then you can see a picture of finding out about each other.

To avoid this, it is necessary that each male has his own female – then he will stop concentrating on his rivals.

Tiger Swordsman has a red-mottled body color. It should be remembered that in nature there are a large number of species of Sword, and they can all interbreed with each other.
