Danio fish breeding


When and how do zebrafish breed

Wild Danio species breed during the rainy season when the water in the freshwater reservoir becomes warm and soft. However, females of wild specimens, caught in winter, had a belly filled with caviar. This means that the reproduction interval is influenced not only by the season, but also by abundant food. Therefore, breeding of zebrafish and other species of fish of the Danio genus is possible at home throughout the year.

Mature Danio: Description

Pink danios and danios rerio become sexually mature, reaching maximum body size. When the water temperature is above 25 ° C, the rate of growth is accelerated. At home, the fish become ready to breed at 75-80 days of life, when the length of the body of the females becomes 25 mm, and the males - 23 mm.

Ovulation of females living in the general aquarium largely depends on the effects of male hormones, which are released from gonopodium. The males pour out into the water the fraction of gonads and the testes homogenate, which contain steroid compounds of glucuronic acid. They also cause ovulation in females.

If males are present in the aquarium for 8 hours, reproduction will begin in the morning. Females that are in isolation for 5 days will not produce eggs. Mature eggs are produced during a single spawning cycle. With a comfortable content of heterosexuals in the tank, in any case, they will begin to multiply, and the spacing between spawns can be one week. The water temperature, which stimulates the process - 22-27 degrees Celsius.

Have you noticed that adult fish can't spawn in a common aquarium? Pay attention to their content. The reasons for the absence of spawning may be the following factors:

  • Diseases of fish of fungal or bacterial origin;
  • The absence of males in the pond;
  • Insufficient fish getting live feeds;
  • Old age fish, or their young age;
  • Calf freezing in female's abdomen.

Now it is necessary to understand how to distinguish between mature individuals, male and female. All types of danios (rerio, pink, malabar, pearl and others) have practical identical characteristics that determine gender. The differences between them are:

  • Females are larger than males, they have a rounded belly;
  • On the body of females, horizontal stripes are faded, as is the common color of scales;
  • During the spawning period, females are calm, slow, and males are active and playful;
  • With the advent of spawning, the color of the male body becomes brighter, the stripes become saturated with color.

How does the reproduction process in pink danios

Pink danios is a fish that is easy to breed, but it also needs special preparation for breeding. The first step is to determine the sex of all the fish, and deposit them for 2 weeks in separate containers with infused water. The second step is the abundant feeding of future producers with live feeds (bloodworm, artemia, daphnia, koretra, tubule).

If the fish begin breeding in the walls of the common aquarium, immediately deposit them in the spawning. Otherwise, producers and other adult fish will eat caviar. In the otsadnik males and females will continue to spawn.

Pink danios spawns in a separate tank. It will not be difficult to prepare it: choose a glass container with a volume of 40-50 liters, pour clean and pre-infused tap water in it with an acidity of 7.0 pH and hardness up to 15 °. A spacious tank will not hamper the movement of fish, which at this time and so very fussy. Water aeration is allowed.

It is not recommended to install in the spawning scenery in the form of soil, stones, wooden snags or caves. The only substrate for spawning can be plants: Javanese or Thai moss, perististotnik, Canadian elodea. To prevent the plants from floating up, they can be pressed to the bottom with small stones (clean and pebbles treated with boiling water). To save the roe, place a fine-mesh separator net on the level 2 cm from the bottom. It will protect caviar from adult fish.

First, in the spawning aquarium they launch a female, which is fed live food for 2 days. When her belly is maximally rounded, you can run 2-3 males, and turn off the light at night. You can put two females and 4-5 males.

In the morning reproduction will begin. Fish can mate for several hours. During this time, the female will be fussy and mobile, leaving behind a lot of caviar (1000-2000 pieces). All of them will sink to the bottom, passing through the grid. Young females can sweep less eggs - from 100 pieces and more.

Upon completion of spawning, producers need to be transplanted into a common aquarium. The mesh from the bottom can be removed, and if the caviar is stuck between the lines, it should be slightly shaken off. In 24-72 hours, the first larvae can hatch. In three days the fry will swim independently. Starter feed - ciliates, live dust, branded feed for zebrafish.

How is spawning in Danio rerio

Zebrafish also breed easily in a spawning aquarium, like pink zebrafish. It is important to provide a good feed with live feed before spawning. What you need to do to spawn danio rerio turned out successful:

  • Pour into a spawning aquarium clean and pre-infused water from the tap. Gradually bring it to a temperature of 26 ° C. Place the plants in the tank at the level of 2-6 cm from the bottom level.
  • See how to breed danio rerio at home.

  • Install the spawning in a well-lit place, or illuminate it with 0.5 W fluorescent lamps. Launch into it females, and then males. At night, turn off the light.
  • The breeding of zebrafish in the aquarium will begin in the morning. If the spawning does not take place, feed the producers with live food over the next day.

  • After spawning, plant males and females into a common reservoir. Replace 10% of the water in the spawn with water of the same temperature. Connect aeration.
  • Finished zebrafish fry will swim in search of food in 4-6 days, depending on water temperature. They are also fed ciliates and chopped feed. You can serve them hard-boiled chicken yolk. It needs to be powdered and diluted with water free of chlorine.

Breeding zebrafish

When choosing "inhabitants" for their aquarium, many people stop at fish of the zebrafish type. The reason is that these fish are very unpretentious in content, have modest requirements for food and get along well with the rest of the neighbors. In addition, Danio-rerio has a fairly simple breeding process, so for its organization you will need only a minimum experience in aquarism.

Danio breeding at home

Breeding this type of fish in an aquarium is quite simple. First you need to select one female and several males. It is easy to distinguish them - the male has pronounced yellow-green stripes on the body and a less full abdomen. On the readiness of the female for spawning will speak a thickened abdomen in the anal fin.

Important: before spawning, selected individuals should be fed abundantly, it is advisable to use a correction.

So, how to organize breeding Danio-rerio? First you need to equip a spawning aquarium. Of course, danios reproduction can begin in the general aquarium, however there is a high probability that caviar will be eaten by other fish.

In the spawning tank, the water should be separated and fresh. Its temperature should be 24-26 degrees. A layer of water should exceed plants by about 5-6 cm. This capacity should be put on the illuminated window sill and in the evening put fish in it. Early in the morning, when the rays of the sun fall on the aquarium, spawning begins. If spawning did not happen on the first day, then the producers should be left in the aquarium for another day, after feeding them with bloodworms. If the next day the situation is similar, then the males need to be transplanted from the females for 4 days and planted again to spawn.

When the spawning is over the fish need to be precipitated, and some of the water should be replaced with settled, the same temperature and composition.

In about 3-5 days from the roe, the zebrafish fry will appear. At first they will resemble strings with thickened heads, but after a few days the fry will begin to swim independently. At this point, they need to be given rotifers, ciliates and nauplii of Artemia. If it is not possible to obtain these feeds, then use hard-boiled and diluted egg yolk.

What you need to know about spawning danios?

To breed such aquarium fish like danios, it is necessary to study in detail the characteristics of their reproduction. Spawning danios can rightly be considered an easy process, because it happens quickly, which cannot be said about other types of fish. The easiest way is for spawning representatives of such species as danios pink and danios rerio. This is a killing fish, the females of which bring a lot of sticky eggs. Spawning danios does not require the creation of special conditions, all that is needed is a glass aquarium, some plants, a separator net, and, of course, well-fed and satisfied producers.


To breed these fish, you must help them in spawning. In nature, Brachidanio rerio and related species breed during rainy seasons, when more water is accumulated in water bodies, its temperature rises by several degrees. Similar conditions should be created in an aquarium - water changes 1-2 times a week, a gradual increase in temperature will become a stimulation for mating games.

When spawning in a common tank, there will be a danger to the brood. Caviar can be eaten by parents, and future fry may not see the light. Plants will not help, the only way out is to prepare a special spawn. Take a glass container with a volume of 50 liters for several fish (1 female and 2 males). You can take a more spacious tank, and run there a few females and twice as many males. Put javanese or Thai moss on the bottom of the spawning ground, they have a soft cover. On top you can lay out the separator grid (2 cm above the bottom). The temperature of the water after starting the manufacturers can be gradually increased by 2-3 degrees, bringing it to 26-27 ° C.

See how to prepare spawning for danios.

How to understand that the female fish is ready to spawn? She has a very swollen abdomen, in which the roe matures. If you have a pink danio, the size of the female's abdomen will increase so much that it will look like a balloon. When you notice pregnancy, add some water from the common aquarium to the spawner, and place this container in the lighted corner. Pink danios spawn like danios rerio.

With the onset of dawn, the males begin to drive the female, hitting on her belly. The filled belly with caviar does not withstand the blows struck, and begins to give out a mass of eggs. Immediately, the roe is fertilized by males, and it falls to the bottom, steamed by plants. There may be a lot of caviar, so it appears within a few hours. After spawning the fish, they should be transplanted back into the common reservoir. After a few days, the caviar lies on the litter of moss, and matures.

How to get healthy fry? The first is to choose the brightest and most beautiful males. Danios can spawn at around one year of age, and housing conditions, feeding can affect performance. The second is that two weeks before spawning you must feed danios rerio with live food saturated with proteins. In addition to parents, fry can destroy aggressive neighbors. A pregnant female is very shy, so you need to minimize stress.

Before the breeding process, transplant males and females to spawn before turning off the light (2-3 hours). The water level should be 10-15 cm above the level of Javanese moss. Half of the water in the spawn should be tap and infused, and the other half - from the general aquarium.

What else do you need to know about danio spawning?

If your zebrafish previously multiplied, then in the future it will be easier to determine their spawning interval. For example, they bred once every 2 months - it means that the female will round out 2 months after the last breeding. If the zebrafish began to spawn in the common tank, they can be safely deposited in the spawning net with the help of a net, where they will continue the process.

Watch a video telling about the features of danios breeding.

If in the evening you feed fish with live food, or replace water in the general aquarium with fresh water, then reproduction can occur in the morning. Then you may not have time to pick up and move all the fish. Consider all details to avoid loss of brood.

There is an opinion that a container in the form of a 3-liter jar is suitable for spawning, at the bottom of which you can place the plants and the string twisted in a ball. If you do not have another tank of glass material, you can use a can, but the fish in it will be cramped. When buying zebrafish and other Brachydanio breeds, remember that they tend to breed like other fish. Therefore, in advance buy another tank for fry.

Aeration in the spawning tank is allowed. Oxygen will enrich the eggs, which will affect their ripening. Larvae can hatch after 24 hours, or after 48-72 hours (warm water contributes to the rapid appearance of the larvae). After three days the fry will swim independently. Starter food for them - ciliates, live dust, boiled egg yolk, ground into powder, feed for frills danios.

The temperature in the pond where the fry live also affects the rate of their maturation. The water temperature of 26-27 ° C contributes to the rapid growth of babies, provided that they get enough protein feed. At an ambient temperature of 22-24 degrees, the fry will grow more slowly.

The grown DaniRerio fry can be given not only yolk or ciliates. A braised beef heart that can replace live food can be a good substitute for live food. Plan your spawning in the summer when high-quality live food is available - Artemia larvae, daphnia larvae, and the strawberry. Small fish can grow on artificial food, if given within 1 month.

Danio care content spawning compatibility photo and video description.

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.


The pink danio rerio appeared in Europe in 1911, in Russia - in 1958. It is accepted to call the motherland Sumatra, Myanmar, Thailand.

It is noteworthy that the translucent body changes color depending on the surrounding conditions. That it seems bright, then pale pink, and sometimes just bluish. The back is greyish-olive, the sides are pinkish-silver. If you look at a certain angle, then stripes of blue or purple colors become distinct. A red line with a bluish border runs along the whole body, which grows dim as the fish grows older, and then disappears completely. The little body is slightly compressed from the sides. Caudal and dorsal fin - yellow-green, anal fin - yellow with dark specks. There are short antennae pointing down.

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 rocks can live at higher temperatures. Depending on the temperature conditions of your home, you may need a water heater to regulate this temperature.

Подождите, когда в аквариуме установится азотистый цикл. Содержание рыбок в неподготовленном аквариуме, где нет установленной биологической среды, навредит их здоровью. Используйте тестовые индикаторы для измерения количества аммиака, нитратов и нитритов. Пока замеры не покажут безопасную концентрацию веществ в воде, не запускайте в резервуар рыбок.

Содержание данио в домашних условиях

Эти рыбки не нуждаются в просторном аквариуме, хотя в нем будут чувствовать себя более уютно. However, if there is no such possibility, then in a small container of 4-5 liters up to 5-6 danios, who never divide the territory and do not arrange demonstration fights, can perfectly get on. The maximum that these tropical minxes are capable of is a long and exciting game.

And, as a rule, mostly males take part in them, who like to chase each other. It should also be borne in mind that danios are great jumpers, so the aquarium should be constantly closed with a special lid with air holes, otherwise your pets will soon be outside. But you need to remember that you need to leave at least 5 cm between the lid and the surface of the water, otherwise some of your pets risk simply breaking during their enchanting somersaults.

Danio is committed not demanding to temperature, and if you forget to take care of water heating, then nothing terrible will happen. Fish feel equally good both at +15 degrees and at +30. However, the best option if the temperature in the aquarium will still be maintained at + 21-25 degrees. But its purity is crucial for the fish, so every week the contents of the aquarium will have to be updated at least 20-30%. Well, and general cleaning should be carried out at least 1 time per month, for which danios will be very grateful to you.

These fish live in the upper and middle layers of water. However, this does not mean that they never sink to the bottom. On the contrary, this is where they seek shelter when they need privacy, or they hide from dangerous neighbors, preferring to avoid conflicts. Therefore, the bottom of the aquarium should be filled with a fairly thick layer of light soil, which is planted with dense low-growing algae. But at the same time it is worthwhile to leave a few free and well-organized places for playing fish.

An aquarium with danios does not require additional aeration, but it still needs constant lighting. Light day for these fish is at least 10-12 hours. If you ignore this requirement, then danios will become sluggish and sedentary, and their luxurious striped color will noticeably fade.


For spawning you need to choose a female and several males (2-3 pieces). Put them all at night in a spawning aquarium and wait for the process. If the conditions in the spawning are suitable, then in the morning the female will begin to spawn. The spawning process is accompanied by active pursuit by males of the female until they break out of the portion of eggs from it. As soon as the eggs fall out under the plants, the males begin to fertilize them immediately. This procedure will occur until the female completely loses all of her calf. At the end of this race, the males look calm and fairly tired, while the female loses the roundness of her abdomen.

After spawning is completed, the producers are removed from the spawn. For one litter, the female can produce about 200 eggs, and for them to survive, it is important to add antifungal agents to the aquarium. As an option, you can apply a two-percent solution of iodine (3 fell to 10 liters of water) or 10 liters of water to 25,000 units of penicillin. After two days, the eggs should ripen and the larvae will appear on the light, which freeze and attach themselves to everything. This will happen within 6 days.

As the last 6 days of immobile hovering, the fry are formed from the larvae, which are first fed by infusoria. After a couple of days, you can give lively dust, and after a week add artemia and cyclops to the diet. If the filtration is satisfactory, you can also give small, dry feed. As young animals mature, soldering should be increased. Start with the chimney and cyclops, and then gradually lower the water temperature and increase the water level.


Danio rerio is compatible with scalars, males, soms, corridors, gourami and guppies, battles and mollies, patsils, iris, rassets, labo, swordtails, tetras.
Limited compatible: with eels and shrimps, barbs.
Incompatible: with cichlids, discus, goldfish, Koi carps, astronotus.FEEDINGIn general, FISHING DANIO is very unpretentious in the diet. So many owners do not worry too long and feed their fish exclusively with dry food. Yes, fish can easily live like this all their lives and give offspring, but in this case their immunity decreases, which means that they are more susceptible to diseases and also grow much slower. Therefore, it is desirable if you do not feed them with one live food, then at least regularly to bring it into the diet of fish.





Silver - pink danios

Danio pink (lat: Brachydanio albolineatus) is a freshwater fish of the carp family, genus Danio. The natural environment of distribution is the water bodies of Southeast Asia, where there is a moderate or fast current. In the rivers and streams of Sumatra, Thailand, Myanmar to this day there are these fish.

External characteristics

Danio pink is characterized by a body of elongated symmetry, slightly flattened on the sides. The length of the body is 5-6 cm. The color of the scales is silvery-pink with mother-of-pearl shimmer. From the base of the tail to the middle of the body there passes a horizontal white stripe with a blue border. In young fish, the color of scales may acquire a cherry hue, with age its color fades.

The fins of this fish are transparent and colorless. Anal fin has a pink hue. Pink danios swim fast, can resist the rapid flow of water to which they are accustomed to in their natural habitat. Schooling fish, prefer a company of 6-8 relatives. Aquarium zebrafish swim in the upper and middle layers of the reservoir. Life expectancy in captivity is 3-5 years.

Reproduction of pink danios is possible at the age of 6-8 months. During the spawning period, sex differences are visible: the males are smaller and slimmer, they are distinguished by a brighter color of scales. Females have a rounded abdomen, body color is faded.

Look at the pink danios swimming in the aquarium.

Content policy

Aquarium zebrafish pink should be kept in the flock, so they should be placed in a spacious tank of 50-80 liters, with a height of water of 30 cm. These active fish can easily jump out of the aquarium, so it should be covered with a lid. It is important that other species of fish live in the pond. Pink danios are distinguished by shy behavior, and can only seem to be shared with their neighbors.

For aquarium soil, you can use pebbles, river sand, a large fraction. At the rear and side walls of the reservoir, it is recommended to plant the plants with small leaves: hygrophilous Siamese small-leaved, cabombu, Eleoharis, echinodorus tender. Leave a free swimming area near the front glass of the tank. Place snags, caverns or clay pots for shelter in the aquarium.

These aquarium fish are not particularly demanding on the parameters of the aquatic environment. For pink danios, the optimal conditions are: water temperature is 18-22 degrees Celsius, acidity is 6.0-7.5 pH, hardness is 5-15 dH. Once a week, 20-25% of water should be replaced with fresh and clean water. Aeration and filtration of the reservoir are required.

Danio prefer bright lighting, which can be created using fluorescent light bulbs 0.5 watts. Lamps should be installed near the front glass of the tank. A few hours a day it is necessary that the sun's rays fall into the aquarium, they will give the fish a shimmering color.

Pink danios are compatible with calm, peaceful fish. They are recommended to settle with those species that can live in similar water conditions, these are: zebrafish, catfish corridor, tetras, terntions, minors, neons. Can coexist with scalars, gourami, small cichlids. It should not be kept with large fish, or aggressive, predatory species.

These little fish have a great appetite - they eat any kind of live, frozen, dry food (only finely chopped food). Among them are the bloodworm, the chimneyweed, the corelet, the daphnia, Artemia larvae, small insects. You can give chopped lettuce and spinach. To the color of fish was saturated, you can feed them with food Tetra Color.

Watch a video about the maintenance and care of pink danios.

Breeding at home

For breeding of pink danios, it is necessary to take several producers - 2 males and 1 female. A pair spawning is also possible, in which 2 females and 4 males can participate. If upon reaching sexual maturity, reproduction does not occur, a cyst forms in the females in the abdominal cavity, which is life-threatening and leads to infertility. It is almost impossible to strain caviar in small fish, therefore, upon reaching 8-12 months, females should spawn.

2 weeks prior to spawning, females are transferred to a spit where they are fed with live food. They will gradually grow abdomen, which indicates readiness for reproduction. The volume of the spawning tank should be 10 liters per female. At the bottom of the tank should be placed Javanese moss or separator mesh. Water for spawning can be taken from the tap, and defend it for 2-4 days. To achieve a hardness of 10 °, tap water that has been separated can be mixed with 1/3 of boiled water. The temperature of the water in the spawning should be 24 o C, acidity 7.0 pH. The water level in this aquarium is 6-8 cm above the level of the separator grid or Javanese moss.

Reproduction begins with the launch of males in the spawning in the evening, and females in 2-3 hours. Gradually increase the temperature by 3-4 degrees, so that it is 26-28 degrees, after preparation you need to turn off the lighting.

Reproduction will occur when the light is turned on in the morning, or the first rays of the sun fall on the aquarium. Spawning will last for several hours, during which the zebrafish will sweep 100-200 eggs of a translucent texture, a milky color. After spawning, males and females should be removed from the spawning tank.

Eggs are incubated for 24-48 hours, after which the larvae hatch. Fry will swim independently in 3-4 days. Starter food for babies - ciliates, Artemia larvae, live dust. Later, the fry can be given a crushed tubule, the danio brand fodder. As the fry grow, they can be sorted, and transferred with a net to different otsadniki.

Danio leopard content breeding compatibility photo description.


Great fish for a common aquarium. Gets along with his relatives (for example, danio rerio) and other peaceful fish. However, a pack is very important for leopard danios, and they need to be kept from 7 of them. In such a pack, they are actively playing and chasing each other, without causing any damage, however.
There is an opinion that danios can reach slow-moving fish with long fins, but in my practice they live quite peacefully with many fish, even with scalars.


A male from a zebrafish female can be distinguished by a more graceful body, and they are a little smaller than females. In females the same large and rounded belly, especially noticeable when it is with caviar.

Detachment, family: Carp.

Comfortable water temperature: 18-24 ° C.

Ph: ph 6.5-7.5.

Aggressiveness: not aggressive.

Leopard zebrafish compatibility: 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.


Danio leopard lives in slowly flowing water bodies of South-East Asia.

The size of the fish is 4-5 cm. The body is elongated, slim, flattened from the sides. The body is gray-white to golden in color, with numerous dark spots all over the body, which can form longitudinal stripes on the tail. Fins have a yellowish tint, may be with small dark specks. The male has a more intense color.

Danio leopard contain in aquarium flock (from 6 copies). Danio leopard can be kept in a 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 18-24 ° 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.


Reproduction of leopard danios is simple and it is an excellent choice for those who want to breed small fish for the first time. The unique quality of leopard danios is that they are faithful to their partner. If a pair is formed, then it exists throughout the life of the danios, and rarely does one of the fish spawn with other danios, even if the pair has died.

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 temperature increase of a couple of degrees, as a rule, spawning begins early in the morning. During spawning, the female will set aside 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 in two days. The 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.

In nature, the leopard does not meet the zebrafish; it is artificially derived from the zebrafish. It is very widespread throughout Asia, from Pakistan to Myanmar. Danio 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.
He was first described by Meinken in 1963 as Brachydanio frankei, later changing his name to Danio frankei, but where he came from, remained a mystery. They said that it was India or Thailand, but no one could indicate the exact location. Over time, we managed to find out that this is a hybrid, derived from zebrafish in Czechoslovakia, by crossing.
