Sword Bearers

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.

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 are trying to use the breed of placium and “mechikov” for optimal results, but so far this is not 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.

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 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

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.

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.

Sword-bearers are old, unpretentious and popular inhabitants of aquariums

Red Sword-bearers: male and female

One of the most popular inhabitants of aquariums are swordtails. Under natural conditions, they can be found in Mexico and several countries of Central America.

They live in ponds, lakes, downstream rivers – reservoirs with standing or slowly flowing water. In Europe, and later in Russia, the Swordsmen appeared at the beginning of the 20th century and immediately won the love of aquarists due to their liveliness, bright colors and unpretentiousness in the content.

By the simplicity of their content, they can be compared, only, perhaps, with a guppy – also a very popular kind of aquarium fish.

Since its introduction in aquariums in Europe and Russia, the swordtails have greatly changed due to the many years of breeders’ efforts. Today, it is almost impossible to find a purebred representative of the species in aquariums, because as a result of these efforts and crossing the swordtails with different types of platilium, many new subspecies of the most varied coloring with fin shapes, which are very different from the original natural version, appeared.

Modern aquarium fish swordtails are red and gold, lemon and black. There are even their varieties of brindle color – combinations of black and red, as well as calico, where the red and black colors are complemented by white, as well as other variants of the color of these fish.

Swordtails breed well in aquarium conditions

What conditions need to create in the aquarium for the Sword

Unlike most aquarium fish, swordtails are not too demanding as to the volume and composition of the water in the aquarium. They quite easily tolerate temperature fluctuations of water, but the optimum temperature for their livelihoods is 22–24 ° C.

About once a week in the aquarium, it is desirable to replace a third of the volume of water and at least occasionally conduct its aeration. It is under these conditions that the growth and reproduction processes go best.

Swordtails love algae thickets, in them young fish hide from adult males and females. Small-leaved plants such as cabomba, toothed elodea, wallisneria and similar algae are very suitable for creating such thickets. When setting up an aquarium for swordtails, care should be taken to ensure that they are among the plants prepared for the home mini pond.

And the surface of the water can be decorated with Riccia – with open bright green moss. But it is not worth much to get involved in aquatic vegetation, there must be free space for swimming fish – this is an important condition for arranging an aquarium.

Swordtails – playful fish, sometimes they can even jump out of the aquarium. To avoid such tragedies, the aquarium should be covered with glass. The vital activity of the Swordsmen is greatly influenced by good nutrition.

They are unpretentious and in relation to feed, they are happy to eat any live food – Cyclops, Daphnia, bloodworms, pipemaker, but they do not refuse from combined feed. It would be good to include in their diet and feed of plant origin.

Since the maintenance and breeding of swordtails are fairly simple, these aquarium fish are most suitable for beginner aquarists. In addition to the ease of care, they are also quite interesting for observation.

In addition, this type of fish is very peaceful, and as they gain experience, an aquarist can add representatives of other types of fish to the aquarium who are already more whimsical in their care.
