All about fish rasbor

Rasbora is a small live and mobile aquarium fish. In nature, she prefers to inhabit quiet rivers and small tropical lakes. There fish swim in schools, trying to stay closer to the surface of the water. Some types of rassor can be kept in aquariums.

In the wild, freshwater rassors usually live in the waters of Southeast Asia, some species are found on the African continent, and they also inhabit the Philippines, India and Indonesia. There, the water is very soft and warm, with an abundance of thickets of dense vegetation, and the branches of large spreading trees cover rivers and lakes from the scorching sun's rays.

Aquariums are small - their size does not exceed 4-5 cm, they have been bred as decorative ones for over 100 years, and throughout this time they enjoy unchanged popularity. The demand for these fish can be explained very simply: they are unpretentious to the conditions of detention, while they have a peaceful character and therefore are perfect for novice aquarists.

Despite the large variety of species, all representatives of the rasbor are characterized by a similar body shape, the colors are dominated by red, purple and silver luminous shades. Sexual dimorphism is poorly expressed, therefore, it is quite difficult for inexperienced breeders to distinguish the female from the male outwardly.

In the wild, there are about 50 types of rassor, among them you can find real beauties: bright, colorful and shiny. Some representatives may be kept in aquariums - these are espey, waste paper, firefly, mera, erythromicron, Harlequin, kubotai, three-line, strawberry, spotted, red-tailed, savba, brilliant.

The most popular are several varieties.

In the natural environment, this fish lives in Burma, it was discovered relatively recently, and in a short time the creatures have become very popular among aquarists. This is one of the smallest types of rassor - the body length of adults does not exceed 2-3 cm, however, bright colors compensate for the lack of size. Males are much brighter and more spectacular than females - they have scarlet fins, which look very beautiful against the background of blue-black sides.

This type of rasbor is popular due to its rich and multi-colored color, which can vary in a wide variety of overflows and semitones, so it is difficult to name the standard shade of this fish. The length of the body of the belt strip does not exceed 3 cm. These are peaceful, but very shy fish, so they like to live in flocks of 8-10 individuals and hide in thickets of aquatic plants.

Quite peaceful and extremely unpretentious in content, creatures that naturally live in the warm rivers of Asia, but rather quickly adapt to existence in artificial reservoirs. These fish are distinguished by a beautiful color - the blue-gray body is covered with yellow specks, and the upper fin has a bright scarlet stripe.

The fish are small, their length does not exceed 2-3 cm, and the average life expectancy is 3.5-4 years. Brigitties like aquariums with dense vegetation, where fish can safely lay eggs and hide fry from adults.

These are people from Indochina and Indonesia, where they inhabited stagnant lakes or weak-flowing rivers, therefore, in aquariums, they should reproduce the appropriate conditions. Brigid fish reach a length of 3 cm. For these fish, the optimum temperature is approximately +23.28 degrees Celsius. These rasbor representatives can eat any food, but the fish are very picky about the purity of the water, therefore breeders should change it by about a quarter daily.

This rassbora is also called wedge-shaped, the subspecies is slightly larger than all the previous ones - its size reaches 4.5 cm. In nature, it is found in the stagnant waters of Malaysia, Thailand, and is common in Indonesia. They adapt to life in artificial reservoirs rather quickly. These fish are distinguished by a golden-silver or golden hue, a translucent tail with a notch, and a red edging along the entire body.

From about the middle of the body to the tail, a dark purple or black blade is noticeable - it is on it that males differ from females, in males it is sharp, and in females it is rather rounded. A comfortable temperature for these fish is 23.25 degrees Celsius.

For disassembly, a fairly large aquarium with a minimum capacity of 50 liters or more is required. The water temperature should be kept within +23.25 degrees Celsius, in order to maintain heating at the desired level, it is advisable to acquire a water thermometer. Water hardness should be about 10-12 units, and the acidity level should be in the range of 6.5-7.5.

It is very important to equip the aquarium with a compressor, which is responsible for the aeration.It will not be superfluous to bring the biocenosis of the aquarium as close as possible to the natural habitat, therefore it is necessary to choose the right aquatic plants and soil. It is advisable to cover the bottom with small pebbles or medium gravel. The plants must be alive, and they must be planted as thickly as possible, however, it is better to leave part of the area free - this will make it easier to care for the tank.

It is desirable, but not necessary, to install a filter in an aquarium with racks. However, if you plan to breed fish, then you will need to purchase the simplest model with coal and a sponge, which will be responsible for mechanical water purification. A water change should be performed every week - usually 25-30% of the aquarium fluid is renewed.

Lighting is required dim, muffled, necessarily scattered. Powerful lighting devices are not suitable for these pets - in such conditions, the fish are stressed, they begin to rush around the aquarium and even try to jump out of the water.

If comfortable living conditions are created for the fish, then they will not get sick. But if the conditions of detention are violated, the rasbora are faced with some diseases.

• Cold - this problem occurs when the temperature drops by 5 degrees or more.
• Fungal infections - also become a consequence of a decrease in water to +17.20 degrees. In order to cure the fish, it is necessary to raise the water temperature to +30 degrees Celsius. In addition, the aquarium should be equipped with compressors and, if possible, filters.
• Oodiniosis - a disease caused by parasites. The danger of this disease lies in the fact that the fish does not show any signs of infection for a long time, it still behaves and looks as usual. The breeder can guess that there is a problem only after he begins to catch the corpses from his aquarium, the disease is especially dangerous for the fry. In order to improve the microenvironment, table salt is added to the water at the rate of 1.5 tbsp. l. for every liter of liquid.

Many ailments rassor associated with a discrepancy between the composition of the water to the recommended level. For example, the excessive presence of alkali causes shock and quick death of pets - it is extremely important to take measurements after each water change. If young animals have been moved to the reservoir, the benchmarks should be taken daily.

In order to avoid the development of dangerous diseases, special attention must be paid to prevention, which involves the following measures:

• regular water changes;
• installation of an aquafilter;
• periodic examination of the fish for the detection of fungus or other infectious lesions of the scales, gills and fins;
• timely cleaning of leftover feed residues;
• maintaining optimal water parameters.

In its natural environment, the rassbora feeds on zooplankton, worms and insects, so in aquariums, pets can also be offered live food: bloodworms, small crustaceans, as well as chopped frozen shrimp and other seafood. However, rassors do not refuse dry food either, the only condition is that the food must be of high quality, since the brightness of the color and decorativeness of the animal largely depends on this.

From time to time, the fish need additional feeding. Usually, dried bread is used for this, as well as boiled water and chilled semolina - these products contain micro- and microelements useful for fish.

Rasboring is often started for fun - this is a very good idea, since these fish can get along with any other non-aggressive inhabitants of the aquarium.

The rassor must be kept in large flocks., they cannot live alone, the absence of "brothers in mind" makes them nervous and stressed, which has a very deplorable effect on their nervous state. Please be aware that in a bad mood, these fish begin to show aggression, and even the most peaceful individuals rush into a fight and can harm an opponent who accidentally fell under their "hot hand".

They get along well with gouras, as well as danios and red-nosed tetras. For small varieties, unpretentious neighbors such as neons are suitable for parsing, and for more authentic varieties, you can even offer shark barbs as companions.

These fish reach sexual maturity by the year, in rare cases this happens a little earlier. When the time is right for spawning, females and males should be housed in separate tanks for 2 weeks. This is not difficult at all, since at this moment the females have a noticeably enlarged tummy.

In the meantime, you can start arranging the spawning grounds. Ethe container must certainly be quite spacious, with a volume of at least 15 liters. The liquid in it must be installed at around 15-20 cm, a protective nylon mesh is laid on the bottom - if this is not done, then the eggs that have fallen out will be eaten by adult fish.

In some areas of the net, small bushes of plants can be placed - in this way the natural spawning conditions will be recreated, when the entire aquatic flora becomes the base for keeping the eggs.

The water in the spawning grounds should be 2-3 degrees warmer than usual, this becomes a signal for pets to reproduce. Regardless of the time of day, the container should have artificial lighting, as well as high-quality aeration. In a prepared container, it is necessary to place from 1 to 6 pairs of females and males, usually in the morning they begin mating games, which are accompanied by a spawn, and this process continues for about three hours.

At such moments, the females begin to lay on one side and squeeze the eggs out of themselves onto the leaves of aquatic plants, immediately after that the males swim up and fertilize them. At the end of the breeding process, the "newly-made" parents should be immediately transplanted away from the eggs, and the liquid level in the spawning tank should be halved.

After a day, the eggs become larvae - in this state they do not tolerate bright light, therefore, it is best to cover the container with a dark cloth immediately after the parental individuals have settled.

After about 7 days, the larvae are converted into fry, so they need to start feeding with live dust or ciliates for accelerated growth.a.
