Danio pink: content, compatibility, breeding, photo-video review


Danio pink

This article depicts and describes the pink, artificial breed danio rerio! True danios pink looks like this:

Order, family: Carp.

Comfortable water temperature: 21-25 ° C

Ph: ph 6.5-7.5, water hardness: 5-15 °.

Aggressiveness: not aggressive.

Compatibility Danio Pink: compatible with all "peaceful fish": danios, terence, minor, tetra, scalar, soma, etc.

Useful tips: In my opinion the most beautiful fish of the kind "danok." Look great flock, on a dark (blue) background of the aquarium film. Fishes quick and gregarious. They can coexist with many species of fish, even with fish of medium and increased aggression: scalar, goura and even with small cichlids.

In order that the pink color of the fish was juicy, I recommend to buy specialized food (for example, Tetra-color).

Description:

Danio pink lives in the slowly flowing waters of Southeast Asia.

A small fish with a body length of up to 4.5 cm. The body is elongated, flattened laterally. Body of fish beautiful pink, along which are alternating white stripes. Fins transparent, colorless.

Fish are kept in the aquarium flock (from 6 copies). Danio pink contain in general aquarium with a length of 60 cm and a volume of 20 liters. The decorations of the aquarium can act - thickets and floating plants, stones, snags. Fishes also need free space for swimming.

Comfortable water parameters: temperature 21-25 ° С, dh 5-15 °, ph 6.5-7.5, regular weekly water changes (1/5) will have a positive effect on the health of the fish. Need filtering and aeration.

Feeding Danio 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.

Reproduction of pink danios

Two males are planted on one female for spawning. Sometimes they practice group spawning with the same sex ratio. Females, like other species of this genus, are susceptible to the formation of a cyst, which makes it sterile. And since the expression of eggs from small fish is problematic, it is better to select females under the age of one year for spawning. The selection of males is less complicated.

Approximately two weeks before spawning, females are upset from males, kept separately and fed abundantly with live food (bloodworm, pipeker, enkhitrei). During this time, the belly of the female is strongly rounded, which indicates its readiness for spawning. For reproduction of pink danios, a spawning area of ​​10 liters per female is settled.

The form of their bodies by nature itself is adapted for rapid movements.
At the bottom of the stack separator grid, which should cover the entire bottom and is located at a height of about two centimeters from the bottom. Instead of separator mesh, you can use small-leaved plants pressed to the bottom by small stones. Water for breeding pink danios should be fresh settled. Approximately one third is boiled for optimal stiffness. It is still better to check. It should be no more than 10 ° dH. pH = 7. The temperature at landing in the spawning area of ​​fish should be the one at which they were kept until that moment. The water level should be no more than 5 - 8 centimeters above the separator grid.

In the spawning area in the evening, the males are placed first, and after a few hours, the females. Set on the thermostat the temperature is 4 - 6 degrees higher. It should be 26-28 ° C. And after that they turn off the light in the breeding ground. The next morning, with the first rays of the sun or with the inclusion of artificial lighting, spawning begins.

It lasts for several hours. During this time, the female sweeps up to two hundred eggs gently milky. After spawning, it is necessary to remove the producers from the spawning area. You can remove the plants and separator grid by carefully and carefully brushing off their eggs.

Incubation lasts about one and a half - two days. And in three or four days the fry will swim, and they will need to be fed with infusoria, Artemia nauplii, living dust. As the fry grow, it should be transferred to larger feed and to a larger aquarium. Puberty reaches sexual maturity at six to eight months.

Reproduction of pink danios is not difficult, but requires accuracy. And you will definitely be rewarded for your efforts.

Appearance and sex differences

Danio rerio has a narrow, long body. This aquarium fish is able to reach 5 cm in length. In the corners of the mouth there is a pair of small antennae directed downwards. The body runs several parallel stripes, painted in yellow, yellowish-green or black and blue. The strips begin near the gill covers and stretch across the whole body to the fin. A distinctive feature of females - stripes in the middle of the abdomen thicken, becoming narrower to the tail and head. The female has a more dense abdomen. The rest of the fins are yellowish white.

Danio rerio content

Danio rerio fish unpretentious. These fish are able to live even in very small aquariums. In the aquarium of 5 liters, you can inhabit about 5 fish. They prefer to live in flocks and stay in the upper layers of water. It is necessary to cover the aquarium. Danio is extremely shy and able to jump out of the water. Males are very playful. A true pleasure to watch their catch-up games. Part of the aquarium is required to plant. A place for free swimming requires considerable. Since the aquarium will contain a large number of plants, it should be well lit.

Temperature control for these fish is not important. The danio rerio feel equally comfortable at both 15 and 30 degrees. However, if you decide to start breeding danios, then you should remember that their reproductive qualities increase at a temperature of 25 degrees.

Any dry will suit as food, thoroughly ground before feeding. Either lively small food is also suitable.

Danio rerio

Order, family: Carp.

Comfortable water temperature: 20-24 ° C.

Ph: ph 6.5-7.5.

Aggressiveness: not aggressive.

Compatibility Danio rerio: compatible with all "peaceful fish": danios, terence, minor, tetra, scalar, soma, etc.

Useful tips: Very common fish. Fishes quick and gregarious. They can coexist with many species of fish, even with fish of medium and increased aggression: scalar, goura and even with small cichlids.

Now it is considered that the color is yellow-green with a metallic luster, and 4-5 dark blue stripes are walking along the body. This statement is confirmed by the existence of a leopard variety.

Young representatives have short fins. But as they grow, they become voile. The fins give their owners an enchanting look. The edges of the voile fins may have a yellow color.

In the wild, adults reach 6–7 cm. Aquarium dwellers, as a rule, are 4.5–5 centimeters. It is advisable to keep flocks of at least seven to ten fish.

Males are somewhat slimmer than females, and also have more saturated colors. Females have a more rounded abdomen especially after puberty.

Keeps most of the time in the middle, upper layers. Life expectancy is about three years. Sometimes with good content they live to five years. They become sexually mature when they reach the age of six to eight months.

Zebrafish breeding

Reproduction also takes place without any difficulties. But the fish is the fawning. Therefore, without preliminary preparation is not enough.

About a week before spawning, males should be separated from females and kept separate from each other. The female from the male can be distinguished by a more rounded abdomen and a less saturated color of the yellow-green stripes. Before spawning, producers need to be abundantly fed, preferably with a chowder.

Spawning can serve as an aquarium with a volume of 10 liters (in extreme cases - the usual three-liter jar). Cover the bottom with luster, peristolistnikom or fontinalis. I also had positive results with the usual elodea. Plants gently press down with small pebbles so that they do not rise to the surface. You can also use a grid that has cells of such size that the eggs freely pass through them. But its cells should be cramped for manufacturers.

Water should be fresh settled for at least 2 days. Temperature 24 - 26 degrees Celsius. She poured a layer of about 5 centimeters above the plants.

In the evening two males (maybe three) and one female are planted in the spawning prepared in this way. The readiness of the female for breeding is indicated by a thickened abdomen near the anal fin. Capacity put on a well-lit window. Danio rerio reproduction begins in the morning when the first rays of the sun fall on the breeding ground. The female can sweep 50 to 400 eggs at a time.

If spawning did not happen on the first morning, the producers need to be held in the spawning area for another day after feeding them with small bloodworms. If now there was no spawning. That males need to be transplanted from females and after 3-4 days to plant again to spawn.

There is one peculiarity - if the spawned female is not planted again to spawn in 7-10 days, then it can lose the ability to reproduce.

After the end of spawning, manufacturers should be precipitated, and half of the water should be replaced with fresh settled, of the same composition, of the same temperature.

Danio rerio

After about 3-4 days from the eggs the larvae appear, which for several days hang on the glass jars. They have the appearance of strings with thickened heads. After a few days, the fry begin to swim. As soon as the fry swim they need to be given ciliates, rotifers, nauplii Artemia. If the feed is very tense, you can feed up boiled egg yolk boiled in steep water. You only need to give it very carefully in small portions, as it spoils the aquatic environment very much. The results will be somewhat worse.

As the fry grows, food for them can and should be enlarged. For the older fry, small crustaceans can be given - daphnia, cyclops. Grown fry as they grow must be transferred to a more spacious vessel.

As you can see, this representative of the underwater kingdom can be a worthy decoration of the general aquarium of a novice aquarist. A flock of these fidgets can revive any underwater landscape. Danio rerio fish resistant to disease. If you do not create extreme conditions, they will long please your eyes with their endless game.

Description:

Fish Danio rerio lives in slowly flowing water bodies of Southeast Asia.

A small fish with a body length of up to 4.5 cm. The body is elongated, flattened laterally. Along the body of the fish are alternating blue and white stripes that start from the gill covers and end on the tail fin. The tail and anal fins are striped. The remaining fins are clear, colorless.

Fish are kept in the aquarium flock (from 6 copies). It is possible to contain Danio rerio in the general aquarium with a length of 60 cm and a volume of 20 liters. The decorations of the aquarium can act - thickets and floating plants, stones, snags. Fishes also need free space for swimming.

Comfortable parameters of water for the content of zebrafish: temperature 20-24 ° С, dh up to 15 °, ph 6.5-7.5, regular weekly water changes (1/5) will have a positive effect on the health of the fish.

HABITATION IN NATURE

Danio rerio fish were first described by Hamilton in 1822. Homeland fish in Asia, from Pakistan to India, as well as in small quantities in Nepal, Bangladesh and Bhutan.

There are dozens of different variants of color and shape of the fins of the zebrafish aquarium fish. The most popular are voile danios, albinos, danios rerio red, pink danios, and even now artificially colored species have become popular. These zebrafish are genetically modified, and are available in bright, fluorescent stains — pink, orange, blue, green. Although this color is very controversial, as it does not look natural, but so far the negative effects of interfering with nature are unknown, and such fish are very popular.

Danio rerio inhabits streams, canals, ponds, rivers. Their habitat depends largely on the time of year. Adult individuals are found in large numbers in the puddles of the rainy season and in the flooded rice fields, where they feed and spawn. After the rainy season, they return to rivers and large bodies of water. In nature, zebrafish feed on insects, seeds and zooplankton.

COMPATIBILITY WITH OTHER FISH

Great fish for a common aquarium. Gets along with related species, and with most other aquarium fish. Better contain from 5 pieces. Such a flock will respect its hierarchy, and less prone to stress. You can keep with any small and peaceful fish. Danio rerio chase each other, but this behavior is not aggression, but a way of life in a pack. They do not injure or kill other fish.

Danio rerio - a fish that everyone knows

Danio rerio (formerly Brachydanio rerio, and now Danio rerio) is a live, schooling fish that reaches only 6 cm in length. It is easy to distinguish it from other danios, running along the blue lines along blue lines. This is one of the very first aquarium fish, on a par with the macropod, and over the years it is still popular. Danio rerio is very beautiful, inexpensive, and great for beginners and experienced aquarists.

These unpretentious and beautiful aquarium fish are great for beginners. They are very simply divorced and easy to feed the fry. Since this is a schooling fish, they need to be kept at least 5 in an aquarium, preferably more. They get along with any peaceful and medium-sized fish.

The main thing is that all these species are easily accessible and can live in very different conditions without problems. They can even live without heating the water, as they withstand a rather low temperature of 18 ° C. And yet, although they are very hardy, you should not keep them in extreme conditions. By the way, do not be surprised if you see that the flock of danios spends a lot of time at the filter, where the aquarium has the strongest current. They just love the flow, as they live in nature in streams and rivers.

Habitat in nature

Danio rerio fish were first described by Hamilton in 1822. Homeland fish in Asia, from Pakistan to India, as well as in small quantities in Nepal, Bangladesh and Bhutan.

There are dozens of different variants of color and shape of the fins of the zebrafish aquarium fish. The most popular are voile danios, albinos, danios rerio red, pink danios, and even now artificially colored species have become popular. These zebrafish are genetically modified, and are available in bright, fluorescent stains — pink, orange, blue, green. Although this color is very controversial, as it does not look natural, but so far the negative effects of interfering with nature are unknown, and such fish are very popular.

Danio rerio inhabits streams, canals, ponds, rivers. Their habitat depends largely on the time of year. Adult individuals are found in large numbers in the puddles of the rainy season and in the flooded rice fields, where they feed and spawn. After the rainy season, they return to rivers and large bodies of water. In nature, zebrafish feed on insects, seeds and zooplankton.

Description

The zebrafish has a graceful, elongated body. Each lip has a pair of whiskers. They rarely reach a length of 6 cm in an aquarium, although in nature they grow somewhat larger. It is believed that the nature of the rerio do not live more than a year, but in the aquarium the duration is from 3 to 4 years.Her body is painted in a very pale yellow color, and is covered with wide blue stripes that go to the fins.

Difficulty in content

An excellent fish for novice aquarists, and an excellent choice for a common aquarium. Danio rerio eats any food that you offer him. They perfectly tolerate very different water parameters and can live even without water heating.

Feeding

In nature, the zebrafish feeds on various insects, their larvae, and seeds of plants that have fallen into the water. In the aquarium, they eat all kinds of live, frozen or artificial food, but they prefer to take food from the surface of the water, less often in the middle and never from the bottom. They are very fond of the pipe maker, as well as artemia.

Content in an aquarium

Danio is a fish that are predominantly in the upper layers of water. Technically they can be called cold-water, living at a temperature of 18-20C. However, they adapted to a very large number of different parameters. Since there are a lot of them and successfully divorced, they adapt well. But still it is better to keep the temperature of the order of 20-23C, they are more resistant to disease.
It is better to keep danios rerio in a flock, from 5 individuals and more. So they are the most active and least susceptible to stress. For such a flock, there will be enough an aquarium of 30 liters, but more is better, since they need room for swimming.

The ideal conditions for the content will be: water temperature 18-23C, ph: 6.0-8.0, 2 - 20 dGH.

Compatible with other fish

Great fish for a common aquarium. Gets along with related species, and with most other aquarium fish. Better contain from 5 pieces. Such a flock will respect its hierarchy, and less prone to stress. You can keep with any small and peaceful fish. Danio rerio chase each other, but this behavior is not aggression, but a way of life in a pack. They do not injure or kill other fish.

Gender differences

One can distinguish a male from a female in a zebrafish by a more graceful body, and they are a little smaller than females. The females have a large and rounded belly, especially noticeable when it is with caviar.

Breeding

An excellent choice for those who want to breed fish for the first time. Spawning in the zebrafish is simple, the fry grow well, and the fry themselves are quite a lot.

Aquarium for breeding should be filled with water about 10 cm, and on the bottom you need to put small-leaved plants, or a protective grid. Unfortunately, parents greedily eat their caviar.
The stimulus to spawning is a rise in temperature by a couple of degrees, as a rule, spawning begins early in the morning. During spawning, the female will lay off from 300 to 500 eggs, which the male will immediately inseminate. After spawning, parents need to be removed, as they will eat caviar.
Caviar will turn out within two days. Fry are very small, and can be easily removed while cleaning the aquarium, so be careful. You need to feed it with egg yolk and infusoria, as it grows, transfer to larger feeds.

Rherio - genetically modified danios

Danio rerio (lat. Brachydanio rerio, today - Danio rerio) is a freshwater fish that belongs to the carp family. The species received a scientific description in 1822. Today, zebrafish are popular aquarium fish that can be kept at home. In danios fish natural habitat - water bodies of Southeast Asia. They prefer rivers, lakes and canals with a slow current.

They swim in the upper layers of water, plying between stalks of aquatic plants and herbs that hang in the water. Zebrafish feed on small invertebrates, insect larvae. Spawning occurs with a change in water temperature during the rainy season. Fish eggs fall on the thickets of aquatic vegetation, for them it is a safe place.


External characteristics of fish

Wild and aquarium danio rerio look the same - a striped pattern is visible on their body. The symmetry of the body is narrow, flattened on the sides, the length of 4-5 cm. Horizontal stripes of yellowish-green and violet-blue hues pass along the body, alternating between them. In females, these bands are wider than in males. During the spawning period the stripes on the body of the males become bright. The color of the fins is yellow-white, the dorsal fin has a dark border. In females, the body is rounded, with a full belly. Males are slightly smaller, differ angular body.

There are varieties of danios rerio with different variants of color scales and color of fins. Nowadays, Danio aquarium with veiled fins, albinos, red, pink, green, artificially colored specimens are common. There are genetically modified fish in which the jellyfish or coral gene is introduced. They have a fluorescent flare of scales in pink, orange, green, blue colors (Glofish). Such aquarium pets look beautiful, as long as there is no evidence of their negative impact on the environment.

Watch a video about the content and breeding of zebrafish.

Not long ago, genetics from Southeast Asia bred the genetically modified zebrafish breed with a red tinge of scales, and called it Red Zebra (Red zebra). Although outwardly it differs from the ordinary Brachydanio rerio, but to keep it just as simple, the style of behavior and the habits of the fish are identical. The bright color of the body - a consequence of changes at the genetic level, which are inherited. The use of dyes, or special injections is unacceptable.

Content policy

Danio rerio - unpretentious aquarium pets, suitable for beginners. The nature of a peace-loving, agile, playful. Swim fast, high reaction rate, thanks to which they quickly hide from danger. Can live in small aquariums. Schooling fish, it is advisable to immediately settle into the aquarium 6-8 fish. Swim in the upper and middle layers of water.

The tank should be covered with a lid - these bouncy fish can easily end up outside the reservoir. Males of fishes are playful, they can periodically catch up with each other, or “intimidate” females, thus establishing hierarchical relations within the pack. In the tank of 10 liters, you can settle 4 fish, but it is better to install a spacious aquarium, and there to settle a flock of more fish.


Plant plants in an aquarium: sagittarium, cabomba, vallisneria, echinodorus, cryptocoryne, geleoharis, myriophyllum, javanese moss or ferns. They will saturate the water with oxygen in case of problems with aeration. Leave free space at the front glass of the tank so that the fish can swim there freely. Lighting is recommended saturated, 10-12 hours a day with fluorescent lamps. Sunlight allowed for several hours a day. Aeration inside the reservoir should be constant, filtration - due to the internal filter with a weak flow of water.

Permissible water temperature: 22-25 ° C, although zebrafish can tolerate wider temperature ranges. Warm water reduces the level of oxygen in the water, but it contributes to the rapid development of eggs and fry. Also the elevated temperature of the aquatic environment serves as a stimulus for spawning.

See how danio-rheo spawn happens.

Once a week, update 20% of the water in the aquarium to be fresh and clean; do not forget to insist on it and measure the parameters with a water thermometer and an indicator of acidity and hardness. The recommended hardness of water is 5-15 °, acidity is 6.5-7.5 pH. Brachydanio rerio eat different types of feed: live, vegetable, artificial. Food should be chopped. Bloodworm, tube maker, koretra, daphnia, cyclops, insect larvae, ciliates - compulsory food with protein content. You can feed with pounded egg yolk, branded feeds in the form of flakes and pellets. Aquarium fish will not give up chopped vegetable food - lettuce, nettle, dandelion, spinach.

In the general aquarium Brachydanio rerio easily get along with small fish, which have a calm and peaceful nature. Somiki corridor (speckled, panda), tetras, minors, rasbora, neons, terntions are suitable as neighbors. It is impossible to keep with goldfish, barbs, large cichlids, swordtails, large catfish.

What are the breeds Brachydanio rerio

Due to the endurance of zebrafish embryos, they are used as a material in the field of genetic engineering. The result - the emergence of new forms of fish with different fins and body color. The most well-known breeding forms - "Glofish" (Glofish), with voile fins, with leopard color. There are other breeds.


Danio rerio with mutant body color (Bleached blond) was obtained after manipulation of insertional mutagenesis. The hybrid form of the fish lost its standard color with black pigment in the melanocytes due to the inability to produce melanin. Wild Danio rerio in the first days of life (fry) have a dark color of the body, and hybrids of this form are born translucent.

Danio rerio Glofish - genetically modified fish, whose little body shines thanks to the bioluminescence genes. The first hybrids appeared in 2003, now they are found in many aquariums in the world. Thanks to the introduction of jellyfish DNA, the fish emit a glow. The forms of such fish with different skin tones are derived.

Danio kyathit (orange) is a modified form of zebrafish, a model object for research. The color of the fins is yellowish, the edges have an orange edging. The fish is small, up to 5 cm in length. The body color is orange with horizontal blue stripes. Caudal fin translucent, with blue shimmer.

How to care for Danio fish

All aquarium fish of the genus Danio are beautiful and unpretentious pets. Danio rerio, pink danio, Malabar, Thai, leopard and other species are suitable even for beginning aquarists. Proper maintenance and proper care for these pets are the main components of their harmonious life.

How to set up an aquarium for Danio settlement

Choose a large enough aquarium for schools of fish (6-8 adults). Danio rerio and other related species thrive in a flock, and the more it is, the better. Ideally, you should purchase five or six danios, and settle them in a tank that contains 50-100 liters of water. A group of three fish will quietly fit in a smaller tank, but this can lead to stress or aggression. Never keep a zebrafish alone or in a small tank of 10-30 liters.

Next, you should add to the aquarium soil and plants. Line a layer of well-washed sand or gravel to the bottom of a dry tank. Add plants and decorations. Along the perimeter of the reservoir, it is better to place the plants so that they leave the front part of it free for the fish to swim. Danios are active fish that need a lot of space to swim in the upper and middle layers of the reservoir. The scenery is necessary so that the fish can hide, but they should not restrict their movement.

Pour water into the aquarium. It must be plumbing and infused. The dH level should correspond to the indicators of 5-15 °, the acidity - 6.5-7.5 pH. Allowable temperature at which the content of danios is possible is 22-26 ° C. You may have to insist on water for 2-4 days.

Install aquarium equipment: filter, air pump, aquarium lighting, thermometer and standard accessories for any aquarium. Zebrafish, pink zebrafish prefer a temperature of about 21-24ºC. Hybrid breeds can live at higher temperatures. Depending on the temperature conditions of your home, you may need a water heater to regulate this temperature.

Wait until the nitrogen cycle is established in the aquarium. Keeping fish in an unprepared aquarium, where there is no established biological environment, will harm their health. Use test indicators to measure the amount of ammonia, nitrates and nitrites. Until measurements show a safe concentration of substances in the water, do not run fish into the tank.


How to care for Danio. Diseases

To care for the fish delivered them a minimum of stress, you need to run them into the aquarium slowly. This can prevent fright and loss of scale color. Danio rerio, as well as bright pink danios should settle in the new water gradually. Take a portable package for fish, and pour water there, in which they lived danios. The temperature of the "portable" and aquarium water should be the same.

Then lower the package into the aquarium, holding it. Fish so quickly get used to the new environment. You can put a pack of fish in a large package, so it will be easier for them to acclimatize. Do not forget that 2 weeks before the relocation of fish in a common tank, they must be quarantined.

Watch the video about care, content and danios.

Danio rerio non-aggressive fish, so their content does not give you trouble. They do not bite, do not cause each other trouble. The first time after the settlement, can be shy. There have been cases when danios did not want to show up before settling in the aquarium other types of small fish - corridors, neons, minor and others.

The danio’s swimming style is sharp, they are gaining high speed. They swim in the middle and upper layers of the reservoir, taking food there. It is important that all pets have enough food, including the bottom residents.

In the aquarium should be aquatic plants. What is it for? First, living plants saturate water with oxygen. Secondly, during the absence of the owner, the compressor with aeration can be turned off. Lack of oxygen will negatively affect the health of pets. Fish love a slow undercurrent.


Clean the water promptly. Once a week, replace 20% of the aquarium water with clean, infused water. Install an internal filter in the tank that will suck up the remnants of food, harmful substances. The beneficial bacteria that appear in the filter sponge will enrich the water with beneficial microflora. If the remaining feed remains on the bottom, siphon the ground with a hose.

Improper care of the fish can cause their diseases. Dropsy - a disease that appears suddenly. The eyeballs of the diseased fish bulge, the scales bulge, the belly swells. Unfortunately, dropsy often leads to the death of a pet, so adjust the parameters of the aquatic environment and monitor the cleanliness and feeding.

In addition to infectious diseases, hybrid zebrafish have chronic diseases. The most common disease is spinal curvature. First, the central part of the spine will begin to bend. Deformation occurs after severe stress. Later, the gills and scales will bulge, and the fish may die. Be careful when choosing the scenery, and choose the right neighbors for fish.

Feeding rules Neighborhood

Danio rerio - omnivorous fish that can take different types of feed. However, overfeeding can cause various diseases. Not eaten feed will begin to oxidize in water, forming a beneficial environment for the growth of microbes. Danio are small pets, so it will be difficult to recognize diseases and treat them. The stomach of these fish is about the size of their eyeball.

Look at the common aquarium with danios.

Food can be given in small portions 1-2 times a day, and so that they eat it in 3-5 minutes. Overfeeding can cause bloating and accumulation of toxic substances in the body. Feed these fish is recommended branded feed manufacturers Tetra, JBL, General Duna, Dennerle, Sera. You can give the fish live and frozen, vegetable and dry food. They love bloodworms, tubule, daphnia, corret, artemia. Do not give up chopped leaves of lettuce, dandelion, spinach, boiled and powdered egg yolk.

Proper maintenance of the fish, and caring for it are possible under the condition of correct compatibility with other fish. What types of compatibility is possible with zebrafish and other Danio from Southeast Asia? Do not settle them with large, aggressive and slow fish. Successful compatibility will be obtained with small fish, such as terntion, minor, rasbor, neon, tetra. Get along well with other types of danios. Not recommended content with large catfish, cichlids and scalars, eels, goldfish and koi carp, barbs, discus.

Danio - maintenance and care

Danio rerio is one of the most popular and amusing species of fish, differing from the others in its ability to jump out of the water.

However, the maintenance and care of danios is quite simple, these fish are unpretentious and non-conflict. Thanks to their amazing color (there are 12 types of them), they always become an ornament to any aquarium. In our article we will share with you tips on the maintenance and care of danios, so that your tiny pets always feel good and continue to delight you with their playfulness and beauty for a long time.


Care and maintenance of danios at home

Since in the event of an approach of danger, these fish can jump out of the water directly into the air so that the pet is not lost, the aquarium should always be covered with a lid. The optimal distance from the water to the lid is about 3-4 cm, so that jumping out, the fish will not hit the hard surface and not hurt.

Keeping danios and caring for them at home is quite simple. Fishes mostly swim in the upper layers of the water, where oxygen is the most. In this regard, you do not need to install additional aeration of the aquarium.

Danio rerio live in groups. Therefore, if you decide to purchase them, buy 8-10 individuals at once. Since the size of these fish is small - about 4 - 5 cm, an aquarium with a volume of 6 to 7.5 liters is quite suitable for their comfortable living. The optimal water temperature for danios should be around 24 ° C. Although its small changes, these fish will respond quite calmly.

If you want to breed danios yourself, then you need to prepare another aquarium - spawning. The thickness of the water in it should be no more than 6-8 cm. After spawning, the female and the male are seated in different aquariums, after which after 7 days the female is started again for repeated spawning, in order to avoid her infertility.

Feeding danios is also an important process. For this suitable for this type of dry or live food. It is very important that the food be crushed, otherwise the fish will not be able to swallow large pieces.

Danio compatibility with other fish

If you have replenished your homemade living area with these beautiful water dwellers, you can be calm, because danios get along well with most types of aquarium fish. They get along well with catfish, tarakatum, neon, tetra, gourami, lyalius, swordtails, antsistrusy, patzilii, rainbows, ramings, mollies, battles, guppies, cockerels, scalars, catfish Koridorasy and labo. Also "Danički" get along quite well with snails, shrimps and ampouleries.

Despite the good danios compatibility with other fish, there are some caveats. If you have a barb or some other kind of more aggressive fish living in your tank, don’t live with them a voile danios, because more nimble tenants can damage or bite off their veil and long fins.

You cannot keep danios in the same aquarium with goldfish, eels, cichlids, astrotonus, discus and Koi carps.

Diseases danio rerio

Unfortunately, despite all the charm and unpretentiousness of these fish, they have one flaw. This is a congenital danios disease, which appeared from breeders - a curved spine. The main symptoms are rearing scales, splayed toward the gills and slightly bulging eyes. More often, they all appear after fright. A few days later, the central vertebra starts to bend near the zebrafish, and as a result, after a while the fish dies.

A well-known danios disease is also dropsy. In fish, rearing scales appear, eyes bulge, the belly swells and eventually death occurs.

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.

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.

Differences between sexes in pink danios and rerios

Danio is one of the most popular aquarium fish that has been loved by many. If you decide to breed them at home, you should buy healthy fish, a female and several males, or 2 females and twice as many males. At a young age, the sex differences in fishes are mild, and before spawning, they will become more noticeable.


How to know the sex of the fish - the main differences

Brachydanio rerio, or danio rerio - freshwater fish of the carp family. They live in the reservoirs of Southeast Asia, where the water is relatively warm. The standard color of danio rerio is bluish-green, on the body there are several horizontal stripes of yellowish tint. Characterized by schooling behavior, so it is difficult to distinguish the sex of a fish in a flock. All Brachydanio rerio breeds have the same sex differences.

If you are new to the aquarium business, buying Danio rerio or another type of Danio can be a puzzle. In the otsadnik, where they will be sold, can swim a large flock of fish. You can buy all at once, or 5-6 fish at once, 8-10 fish. Surely, among all there are at least a few males or females. Young zebrafish are very similar to each other, they do not have sexual dimorphism. The color of the body is identical, as are the sizes, the fins are commensurate.

Watch a video on how to determine the gender of danios.

When you purchased a flock of fish, then in a few months they will form a body. Adults, sexually mature danios will differ in size. The main difference between a male and a female is the difference in body length. In the female it is large, rounded, and the male is distinguished by the angular symmetry of the body, thin and shortened.

Do not forget to pay attention to the color scales. The zebrafish male has horizontal stripes brighter than the female. This feature is perfectly visible during the spawning period, when a female fish looks for a partner with a brighter color. Females are always faded, they do not need to attract attention to themselves. Their task is to carry caviar. As for this type of fish, like pink danios, the male can become very bright during spawning, the body color will be bright pink, even cherry.


It is also worth studying the behavior of fish during the mating season. The behavior of males and females is a clear difference that characterizes their social roles. The females are usually sluggish, their movements are smooth and cautious, and the males swim abruptly, chaotically around the female, develop a high swimming speed. In preparation for spawning, the males are pushing the female into the belly, helping her to release the eggs.

One of the easiest ways to determine the type of pink danios and danios rerio is to look at the anal fin of a small fish. In the male it is pointed, short, the so-called "gonopody", through which the milt will be released. In females, anal fin is round and large.

Look at the flock of danios rerio in the aquarium.

It is important to learn to distinguish between the sex, if you plan to breed Brachydanio. If you have any doubts as to what sex your pets are, conduct the following type of analysis: precipitate 4-6 fish into separate tanks with infused and prepared water, where the temperature is 22-24 ° C, and look at their behavior. In a few days, different-sex fish can prepare for spawning - females will round off, and males will begin to compete with each other. In one of the containers there will definitely be heterosexual individuals. Remember that the female produces a lot of caviar - up to 2000 pieces.


Additional recommendations

  1. Good lighting and dense vegetation, soil can help you in determining the floor of the fish. The light spectrum emphasizes the color of scales, and it will be easier to understand which fish is brighter and which one is more faded.
  2. It is advisable to buy adults who have already formed fish from proven razvodchiki. When breeding fish at home, watch the growth of fry, their behavior. Some females grow faster than males.
  3. If a pink danios lives in an aquarium, then the floor is easier to determine. Horizontal lines on the body of males are very bright, give a blue color, the scales are saturated with dark pink pigment, which is noticeable during spawning.
  4. In the male pink danio, the caudal and anal fin is green, while the anal fin is red.
  5. Why do females need a faded body color? During pregnancy, they need to disguise their body to hide from potential enemies. Pregnant females are very slow and clumsy, so they can mimic the color of algae and soil.
  6. A female ready to spawn will always be large. A small, angular body indicates that she is still young.
  7. Malabar Danio is one of the largest representatives of Danio. Sex differences are noticeable at a young age - the body of the female reaches the size of 10 cm, the male - 6-8 cm.
  8. Another way to find out the difference is that male zebrafish can periodically chase females, which is not a preparation for spawning. Such behavior is motivated by the observance of hierarchy in the flock.
