One of the most common and favoriteAquarius fish are voylechvost. A beautiful and quiet inhabitant of the water element is a real decoration of the aquarium, and many associate it with a goldfish from the fairy tale of A.S. Pushkin.
A bit of history
Fish vealechvost was bred several hundredyears ago; her homeland is Japan. Only the "elite" (the emperors and their entourage) could keep such a delight in their eyes for the Mikado. In the 19th century, two pairs of these fish were donated to Daniel Ammen - the Rear Admiral of the US Navy, a passionate aquarist. For several years, the American managed to take out 140 heads of the offspring. Most of the young fell into the hands of notable persons and was placed in cages with goldfish. The result of this neighborhood was a cross-breed that lost its original characteristics. To save a unique species and keep in complete purity the type of this breed was managed by a certain Mulert, in whose hands only 2 pairs of decorative fish fell.
Ryabka vealehvost: description
The most prominent part in the structure of decorativeThe fish is its tail, associated with a lightweight, weightless cloth. Its length sometimes reaches 30 cm, which is 3-6 times larger than the size of the trunk. The tail and fins are transparent; the dorsal is upright, the anal splits.
The fish vealechvost has a short, oblatesides of the body ovoid or spherical. Eyes are large. Body color varies from bright red to light cream and golden. Quite rare are purely black specimens. Aquarists are very popular spotted vealechvosty.
There are such varieties of voyalevostov as:
- skirt and ribbon (depending on the shape of the tail);
- scaly and scaly.
Goldfish voyalechvost: content
The correct content of veiled tails requiresthe presence of a large spacious aquarium - at the rate of 50 liters of water per fish. So, for two vealechvostov the 100-liter capacity with pure, transparent water will be ideally suited. In a 150-liter tank, 3-4 fish can be planted, while providing powerful filtration and a good aeration of water.
Fish voyalehvost, the content of which is notis particularly difficult, sluggish in the movements and loves digging in the ground, so it is recommended to place large sand or gravel on the bottom of the tank. Plants should preferably be chosen with hard leaves and a strong root system: egg, vallisneria, sagittaria, elodea.
Veal-tailed goldfish like cool water: the recommended temperature is + 20-21.aboutC. Every week, it should be updated to a quarter of the volume.
Feeding
An important part of care for vealehvostami is theirfeeding: decorative fish are very voracious and can eat non-stop. Therefore, one should not overeat and feed at the rate of 3% of the weight of the veil tail.
Кормление нужно проводить дважды в день:in the morning and evening hours. The amount of feed should be counted for 10-20 minutes of consumption, followed by the removal of leftovers. Once a week, it is recommended to arrange a day off. In the diet should be present dry aquarium food, plants (scalded leaves of lettuce and nettles).
Features of breeding
The component of the correct content of valelethsis their breeding. For one female should be 2 or 3 two-year-old males. Before spawning (March-April) for 2-3 weeks, heterozygous fish should be kept separately, providing them with abundant feeding. Then determine in the aquarium, equipped with a sandy soil, laid at an angle to one of the sides, with a spawning lattice, a bunch of plants with small leaves.
Readiness of the female to spawn can be determined bya thick abdomen; male - by the presence of spawning rash on the gill cover and notches on the pectoral fins. To stimulate spawning, you can gradually increase the water temperature (up to 24-26aboutFROM).The males then become active, begin to chase the female. The latter spawn: about 10 thousand eggs at a time. Most often this occurs early in the morning, with the appearance of the first rays of the sun. At the end of spawning, adult fish should be removed from the aquarium. The duration of the incubation period is from 2 to 4 days; the appearance of fry occurs within 5 days.
Hatched fry is recommended firstfeed "live dust" - the smallest microorganisms that can be grown on their own or purchased in specialized stores. Traditional starting feed are rotifers, infusoria-shoes, artemia. Two weeks after the appearance of young fish can be translated into a small Cyclops.
Veal-tailed cockerel: features of the structure
Veal-tailed cockerel (fish) is a vivid representative of aquarium inhabitants. Characterized by an almost round body, long and pointed at the end fins: caudal, anal and dorsal.
Vailekhvostye cockerels have a different type of color:
- monochrome (blue, purple, red, green, white, yellow, black, cream);
- two-color (trunk of the same color, fins of the other);
- multicolored (multifaceted colors in the color of the fins and trunk).
With a sudden change in conditions of the fish can become discolored.
The fox fish, which is a cockerel,is able to breathe not only the gills, but also a special respiratory organ, called the "labyrinthine". When in the water, poor in oxygen, the cockerel swims to the surface and swallows the air, which in the labyrinth saturates the blood with oxygen. That is why labyrinthine fish species are not very demanding for water quality, which greatly facilitates their maintenance in the aquarium: there is no special need for filtration and aeration.
Ensure proper care
During the care of fish it is important to protect them from damage to the luxurious tail fins. In the aquarium there should not be snags with needle-like knots and stones with sharp edges.
