Danio - aquarium fish

Danio is not uncommon for our aquariums. Silver-colored flocks of various colors attract the eye with swift movement and playful disposition. What kind of danios is preferable to purchase, how to ensure the best conditions and proper care? This and not only will be discussed further.

The origin and appearance of danios

In the wild, danios live in small warm waters of Sumatra Island, the Malacca Peninsula, India and Burma. The conditions in them are most favorable for danios:

  • warm, slowly flowing water;
  • abundance of algae, where you can hide and breed offspring;
  • A sufficient amount of live food, so important to them during the spawning period.

These fast swimming, oblong in shape, graceful fish have bright striped color. Their length reaches about five centimeters in captivity, only the Malabar Danio is somewhat larger.

Danio is endowed with a pair of short antennae, located at the edges of the oral opening.

Movable playful males outwardly differ little from females, except that in the latter the belly is somewhat wider, and the band on their oblong body is brighter and more expressive at the level of the head.

These inhabitants of aquariums have small fins of yellowish color, only the caudal fin, striped or spotted, is more expressively colored.

There are many varieties of zebrafish, and they all have a unique color.

We provide comfort in the aquarium

Small-sized danios with their peace-loving nature can live next to other non-aggressive breeds of aquarium pets, you just need to take into account that they need a society of their own kind, so you should buy them in groups of 6-8 individuals.

Ideal neighbors for these fish are, for example, gupi, neons or barbs. You also need to keep in mind that these fish prefer to swim near the surface of the water. Therefore:

It is also not necessary to inhabit the home water reservoir with numerous inhabitants - moving danios love open space.

For the same reason, prudently approach the placement of the elements of the aquarium design - shells, flaps, other items should be placed at the corners of the tank or along its walls.

With the vegetation in the pond, too, it is important not to overdo it - sit around the corners of the aquarium plants with delicate leaves, and this will be quite enough for the comfort of your pets.

For breeding danios you can use the same capacity in which they are contained. You only need to worry about additional litter on the bottom in the form of fontinalis or hara. For six females it is enough to plant three males. The comfort of the spawning grounds is provided by a slightly increased temperature, easy aeration and periodic renewal of the composition of the water.


How to optimize the content of danios?

The simplicity of this type of fish, which allows them to calmly relate to small and unsharp temperature fluctuations and slight changes in the composition of the aquarium water, does not mean that the zebrafish are absolutely indifferent to their habitat. They react very negatively to:

  • sudden changes in temperature indicators of water;
  • long stay in the water too cold for them;
  • aquarium water pollution;
  • lack of oxygen in the reservoir.

To make the conditions of the fish optimal, you need to adhere to the following simple rules:

  1. Monitor the water temperature in the tank. The ideal indicator varies in the range of 21-25 ° C.
  2. During the spawning period, this indicator should be slightly increased, in parallel by organizing water aeration, since the volume of oxygen in warm water drops significantly.
  3. Carefully monitor the cleanliness of the home water reservoir, timely remove residual feed and weekly update the composition of the water by replacing it with a 15 percent fresh one.
  4. Aeration is not necessary for zebrafish, but is desirable because it provides enrichment of the aquatic environment with oxygen. You only need to use not too powerful equipment for aeration, so that the inhabitants of the aquarium is not interfered with the free movement.

Danio food preferences

These aquarium pets are unassuming in their diet. They are satisfied with completely different dry feed mixtures of not too coarse grinding. However, traditional food for them is still live food:

  • pipemaker;
  • daphnia;
  • bloodworm;
  • Drosophila and others.

Therefore, a living diet for fish is preferable because it gives them all the necessary components for health and reproduction. In addition, for the playful nature of danios, it is important to self-realize in a kind of hunt for representatives of your lively diet.

As all the varieties of danios are recognizable by their habits, their way of being, their graceful body structure, they are so different in color and peculiarity of the natural design that is inherent in each of their species. However, it is the variety that makes these fish a real decoration of any aquarium.

Silver arrows

Zebrafish are one of the most popular aquarium fish of the carp family. Habitat are stagnant and flowing waters of Southeast Asia. The most popular are the following types: rerio, pink, pearl, olive, orange, Malabar, leopard and Bengal. The fish are quite prolific, their reproduction occurs easily in good conditions.

These freshwater fishes were the first genetically modified aquarium representatives to receive bioluminescence genes in 2003.

Danio

Description

Heavenly

Aquarium danios are considered to be small fish, although in natural conditions their sizes reach 15 cm. Aquarium species reach 8 cm. Depending on the variety, the fish may have a variety of colors. They can be a simple silver color and various bright colors like neon yellow, red and green. Pink danios is distinguished by the presence of a dark red spot on the tail. And the verio have fins, the edges of which are colored yellow.

Their body is elongated arrow-shaped and flattened at the sides. Some species may have antennae. Danio males are much smaller than females. Danios have good health and are resistant to diseases. Fish have a fairly wide list of neighbors with whom they have good compatibility.

Care in the aquarium

Leopard

Aquarium danio fish are completely unpretentious in care and their maintenance at home is subject to even the most inexperienced beginners. The aquarium will fit from 50 liters of elongated shape, which is important to keep with the lid closed so that the fish do not jump out. School danios love to swim in a group, so you need at least 6 of them.

For a soil base is better to take small stones and gravel. Plants can choose any, but not plant them too much space, as the fish need space and good lighting. The same applies to the decor of the aquarium, which should be laid out at the edges. It is undesirable to plant floating plants, as danios used to stick in the upper layers of water. It is necessary to take into account the correct compatibility of the fish with other inhabitants of the aquarium, so that there is no competition in the occupation of a personal area or layer of water.

The most appropriate water parameters will be the following: the temperature regime should be changed depending on the season, in the summer of 20-25 ° C, in the winter of 17-21 ° C. Acidity 6-7.5, hardness not more than 10 °. It is important to regularly replace a quarter of the volume of water and high-quality aeration with filtration. It is possible to improve the content of zebrafish using a pump-filter, thanks to which the fish will feel the flow of water as in natural conditions. Fish danios live up to a maximum of 6 years.

Breeding

Pink

Fish breeding occurs the more often the better their living conditions. Water temperature must be reduced in winter. Stimulate reproduction can be at any time of the year.

Before spawning, it is necessary to plant producers, feed them well and raise the temperature to 25 ° C. Fontinaliss moss or glitter is well suited as a substrate. Plants are pressed to the bottom with washed stones, the tank is filled with clean and oxygen-enriched water.

After persecution by the male, the female throws non-sticky caviar, after which the parents are seated in order to avoid eating the eggs. The larvae appear on the 4th day, and on the 7th day you can already feed them with infusoria. Mature fry are fed with cyclops and live dust.

The reproduction of point danios is distinguished by the unique property of females to remain loyal to the male throughout the spawning period, which lasts up to two months. Danio species can interbreed. Sexual maturity reaches 4-12 months.

Feeding

Rorio

Zebrafish feed on zooplankton in nature, and in general they are absolutely not capricious in terms of nutrition. The main thing is not to feed them up, otherwise the aquarium water will quickly deteriorate. It is enough to feed 2-3 times a day in small portions. If it is possible to feed once a day, it is better to choose the morning hours.

Fish prefer live food more than dry and artificial. It is possible to feed with bloodworms, cortex, daphnia, cyclops, live dust.

Compatibility

Bengal

Danio is quite peaceful and conflict-free fish, well neighboring with other inhabitants of the aquarium. Aquarium zebrafish have good compatibility with small fish such as neon, macropoods, rasbor, guppies and gurs. Keeping fish is also possible with cardinals, ternation, nanostomus.

Poor danio compatibility with large or aggressive fish such as cichlids and goldfish.

Diseases

For the prevention of diseases danios, in the aquarium need good aeration and clean water. Also the cause of the disease may be overfeeding fish. One of the most common diseases in danios is bug-eyed, in which their abdomen increases and their eyes bulge.

Trichodinoz disease is provoked by an infusorium that enters the aquarium together with non-disinfected plants or soil. All treatments are performed in a quarantine aquarium by adding salt and changing water every 2 days.

Malabar

Rorio

View rerio still bears the name "ladies' stocking" or "brachidanio rerio." The fish is a model organism used to study the functions of genes. Rherio reaches up to 7 cm, has a silvery shade with blue stripes. In females, the abdomen is fuller. Rherio have a variety of breeding forms, among which are with veil fins, leopard color and fluorescent transgenic. The type of rerio has an advantage over other species by the speed of development; the fish is formed from an egg to a larva in just 3 days.

Aquarium danios have a lot of advantages due to their character, beauty and ease of care. Compatibility with a large number of other fish and fruitful breeding attract more attention and interest.

Danio pink: content and reproduction

It is believed that to breed and maintain such an ornamental fish, such as danios pink, may even be a novice in the aquarium business. Danio - representatives of a large family of carp - really unpretentious, they are frequent inhabitants of artificial home reservoirs. Still, the features of their reproduction, behavior, feeding, you need to know before they are in the aquarium.

Description

Some call this beautiful fish and another name danio pearl. Indeed, in bright light, her body shimmers like nacre.

Like all typical carp representatives, the danio pink body is flattened laterally, two pairs of whiskers are located at the edges of the mouth, on the sides and on the back of the scale with a brilliant color of a complex combination of colors: blue, olive, gray, green.

The abdomen is pink in color, and in mature males it becomes saturated with bright pink.

Adult aquarium fish reaches 5 centimeters in length, and in nature there are specimens up to 8 centimeters.

The natural habitat of danios is quite large: from India to the countries of Indochina, where the flocks of these fish live in the cool water of small rivers and streams.

Conditions of detention

Excellent swimmers, rapidly and abruptly changing the direction of movement, danios love space and usually live in the middle part of the water.

Aquarium. Therefore, a long rectangular aquarium with a capacity of at least 50 liters is best suited for their maintenance. It is possible to lay small pebbles or coarse-grained river sand on its bottom, and also to dissolve small-leaved aquatic plants. For danios pink it will be exactly what you need.

Lighting. It is necessary to take care of him. If you place the fluorescent lamp closer to the front wall of the aquarium, the appearance of the pink-pearl moving creatures will only benefit from this. It is also recommended to illuminate the aquarium with natural sunlight, at least 2-3 hours a day.

Temperature. There are no special temperature requirements for these fish. They feel good in water of room temperature (from +20 to +23 degrees) with low salt content.

Oxygen access. An indispensable condition is a good constant aeration of water, its high-quality cleaning and periodic replacement. It is advisable to replace from 25 to 30% of the aquatic environment once a week, at least.

Security. The aquarium, where danio pink flocks live, must always be kept under the hood (between the water surface and the lamp), as these frisky decorative carp are not only excellent swimmers, but also excellent jumpers in height.

Compatibility

Danio is a schooling fish, and they are completely non-aggressive towards other inhabitants of the aquarium.

A flock of 7-10 fish, quickly dissecting the water space, does not harm anyone.

Active pink-pearl specimens quite peacefully coexist with such ornamental fish as

  • swordtails,
  • gourami of all kinds
  • loaches,
  • mollies and others.

How to feed

But the appetite for Danio pink is excellent just because of their agility. They are happy to eat any common types of food:

  • bloodworm,
  • Daphnia
  • small insects and their larvae,
  • small plant seeds,
  • frozen mine,
  • as well as ready-made branded feed TetraMin.

True, the abuse of commercial feed should not be.

Difference by gender

Males and females have almost the same color. However, it is still possible to distinguish them, but only at a more mature age.

Females are almost always slightly larger and slower than males. Their coloring is more faded and muffled.

Males, on the contrary, have a slender and bright body with expressive stripes or spots on it.

Breeding


For breeding danios pink, you definitely need a separate aquarium at the rate of 15 liters of water per 1 individual, since in the total capacity the caviar will be quickly eaten.

The requirement for the amount of water due to the fact that in the mating season, and especially during spawning, the fish are actively moving in different directions.

In order for pets to not get hurt, the bottom of the pit should not contain large stones and soil with sharp edges, it is better to cover it with peristristis, Canadian elodea or moss. And in order for plants not to emerge, you can put small pebbles.

Clean, defended water (2 days is enough) in the spawning area should be made a little warmer than in the main aquarium, raising its temperature to +28 degrees. In this case, the liquid should undergo easy aeration.

In the breeding ground, first one female is deposited, it is well fed, mainly in the root, since it contains the necessary nutrients and there is no fat at all. As soon as the female's tummy is strongly rounded (in 10-14 days), two males are placed on it. At night, the light turns off.

The next morning, the female begins spawning, which can last up to several hours. At this time, she randomly tossed from side to side, leaving behind her caviar.

One litter contains from 100 to 200 white-colored eggs, which descend to the bottom of the spawn through the grid cells.

Aeration is necessary to continue, constant lighting is necessary.

The incubation period lasts up to three days. After this time, barely visible fry begin to vyklevyvatsya. After another day, when they are already moving, you can start feeding, gradually increasing the dose as the offspring grows.

In the initial period, live dust is used as food: the smallest plankton, ciliates, rotifers. Suit and dry egg yolk. As the babies grow up, they switch to feeding on larger meals.

After about 5 weeks, when the young growth reaches a size of 2-2.5 cm, it can be transplanted into a common aquarium.

For more than 100 years, aquarists in many countries are happy to keep and breed pink danios. Watch for their movement and color overflow can be hours. Unpretentious bright tomboy rightly are the favorites of both adults and children.

Danio - breeding fish in the aquarium. Reproduction of pink danios

Passion for aquarism in our country has long roots. If we recall Zolotnitsky, from whose books millions of domestic biologists studied his native nature, the popularity of this hobby becomes clear. Nothing relaxes and tunes in a calm way, like contemplating pets who swim slowly in crystal clear water, “floating” between amazingly beautiful plants.

Среди начинающих особенно популярны различные виды данио, размножение которых быстро осваивают даже самые неопытные заводчики. These fish are not too afraid of low temperatures, almost omnivorous, and also have a well-pronounced sexual dimorphism. This ensures the simplicity of their content and breeding. However, let us dwell on the issue of obtaining offspring in a little more detail.

Danio rerio

Why do we describe this type in the article? It's just that with the word "danios" at least 99 percent of aquarists imagine these nimble fishes, which are immediately apparent because of their coloring.

Reproduction features

Speaking frankly, there is no particular difficulty with this process even among beginners who brought danios for the first time. Breeding can be complicated only by the fact that these fish spawn, and are not engaged in live birth like a guppy or swordtail. However, not everything is so terrible.

First, before breeding individuals should be divided into male and female groups that need to be transferred to separate aquariums. How to distinguish females from males? It's simple: in females there is a noticeably more rounded abdomen, and the color of the bands on their body is more distinct. During this period, the selected fish are fully and efficiently fed.

The masters of aquaria say that at this time the diet should include mostly chowder. It contains almost all the necessary nutrients, but it lacks fats.

This is extremely important, as the producers in no case should lose their shape before spawning. However, all zebrafish aquarium fishes, whose reproduction is considered here, have lost their shape, their spawning ability is almost always lost.

Choosing a breeding ground

Since the size of the fish themselves is small, then you should not choose a huge “trough” for them to spawn. A modest aquarium of ten liters is fine. Since these fish come from small and fairly shallow reservoirs, its depth can be no more than 20 cm.

The bottom in no case can not be covered with hard soil, which can be injured danios! Reproduction should assume the most comfortable and safe conditions. Optimally will lay perististischik. However, in the absence of alternatives, an ordinary Canadian Elodie may be suitable.

In order for the plants not to emerge and not unmasked the spawn, they should be pressed down a little with small pebbles. Of course, they should be boiled or calcined in advance so as not to introduce any infection into the aquarium. Experts say that for this purpose it is best to use glass rods, which are much easier to disinfect. In general, danio breeding in an aquarium implies maximum purity.

If you set out to maximally protect the eggs not only from diseases, but also from the producers themselves, it is best to buy a special net. As a rule, these materials are painted green, and the size of the cells is such that adult fish cannot squeeze through them. Above the plants or the grid should be at least five centimeters of water.

Water

As in all such cases, the most stringent requirements are imposed on water. Like many Asian species originating from regions with large numbers of fish, danios for spawning need fresh and separated water. Before you pour into the aquarium, you must maintain it for a couple of days. If chlorine is regularly added to the water supply in your area, the aging time should be increased.

Note that the water should be harvested with a reserve. After spawning it is still useful to you.

Heating water to about 24-26 degrees Celsius, run danios there. Reproduction begins with the fact that in the evening a selected group of producers populates the aquarium.

We settle

As a rule, for breeding it is required to select a group of two or three active males and one female. Carefully inspect the abdomen of the last: in the anal fin, it should be markedly thickened. In addition, be sure to choose the place where you will put a spawning aquarium: in the morning the first rays of the sun should fall on it.

By the way, this is the difficulty for many aquarium lovers. Virtually all types of danios are fish, the reproduction of which occurs precisely at dawn. The female lays around 400 eggs, although the juveniles rarely leave more than 50.

If spawning does not occur immediately

If spawning was not immediately, you should not despair. Producers can be kept in a spawning tank for another day. They should be fed with a small amount of fine and well-washed moth, in every possible way avoiding water pollution. In the case when nothing happened the next morning, the fish should again be divided by gender, keeping in separate aquariums for about three or four days.

Important! All danios are fish, the reproduction of which is an obligatory biological mechanism. Speaking easier, if within a week after the first attempt at spawning, you do not again plant a female for throwing caviar, in 70% of cases it loses its ability to reproduce.

What to do after spawning?

First of all, you need to catch the parent specimens from the aquarium as accurately as possible using a wide net. Sharp movements are better not to do. After that, very carefully drain about half of the water that is in the aquarium. To do this, use a wide siphon, on the socket of which it is better to wear a gauze filter.

After that we fill in the same water that we prepared in the form of a stock (see above). It needs to be poured in slowly and carefully, as the composition of the liquid will differ anyway. If you pour everything at once, part of the eggs (if not all at once) can die.

After about three to four days, the larvae appear. At first, they are fed by their infusoria, moving to more serious food as they grow. Young grows quickly, there are no special problems with it.

We breed pink danios

But what about the other aquarium fish? Danio pink, reproduction of which is not much different from the process described above, still require more attention.

To begin with, the ratio of females to males during spawning is 1: 2 or 1: 1 (rarely). Males in this species are much more active, and therefore a large number of them may lead to the death of a female, which active producers simply drive.

The second difference is water. While zebrafish can spawn almost under any conditions, their pink brethren prefer 10 ° dH (constant hardness), and pH = 7. In most regions of our country, the hardness of the water is much higher, and therefore it will have to be diluted either boiled or distilled.

Like many aquarium fish, danio pink (the reproduction of which we are discussing) prefer a higher temperature during spawning. In this case, it should be approximately 26-28 degrees Celsius.

Are there any other differences? No, all other manipulations are absolutely identical.

By the way, is it possible to reproduce danios in the general aquarium? Yes, and this happens all the time, especially for inexperienced beginners. That's just about the accomplished fact of spawning, you hardly ever know, because the caviar is eagerly eaten not only by the happy parents themselves, but also by other inhabitants of the aquarium. Even if some egg is incredibly lucky to develop to the larva, it will still be eaten.

How the Danio aquarium fish breeds: conditions

Even the beginner aquarist will have no difficulty in obtaining the offspring of the zebrafish aquarium fish. Despite the fact that this is not a viviparous fish, but spawning, time and cost will need a little: a small horizontal aquarium, several plants, pebbles and two weeks of patience.

The question "opened a pet shop. Business is not going. What to do?" - 2 answers

Danio is a small, peace-loving schooling fish of the carp family. In nature, they live in flowing or stagnant reservoirs of Asia. They can even live on paddy rice fields. They are not demanding living conditions and are suitable for content for beginners.
Aquarium zebrafish grow up to 5 cm long, have an oblong body. Color can be of different shades - from whitish to silver, golden, pinkish, depending on the color of narrow longitudinal stripes on a light background. Danio is omnivorous. In aquariums, they usually live 2 years, sometimes 4-5 years.

Preparation of spawning grounds

The zebrafish are small, so a horizontal glass container with a capacity of only 3-5 liters will be suitable as a breeding ground. 3-4 plants are laid out on the bottom, which are pressed down by smooth pebbles. Separated water is poured into the tank, the temperature is 24-25 ° C.
Zebrafish reach sexual maturity in 4-10 months. For the best spawning, experts recommend a week before that every day in the aquarium change up to 20% of water. Fresh water should be separated and have a cool temperature of about 20 ° C.
Then, 3 days before the spawning of females and males, it is better to plant them in different aquariums. The female is distinguished from the male danios by a more rounded abdomen and clearer stripes on the back. Fish during this period are actively fed high-calorie food, for example, bloodworms or koretira.
On the appointed day, the spawning area is transferred to a well-lit place and one female with a belly that is clearly thickened at the anus and two or three active danios are planted into it.

Danio breeding

After the fish settles down, spawning occurs the next morning, at dawn, or in a day. It is interesting to observe how the males start chasing the female and chasing her all over the breeding ground, striking directly at the belly of the fish. Thus, they stimulate her to release caviar, which is immediately fertilized.
Caviar gradually, approximately within an hour, precipitates and attaches to the bottom of the spawning grounds. After spawning is completed, danios are transferred to a common aquarium. Pebbles from the bottom of the spawning area are removed to make the plants surface. At the same time, transparent balls-eggs are clearly visible.
After 3-5 days, fish appear from the eggs. They grow quite intensively. Juveniles are fed with infusoria, "live dust", special food for fry.
The zebrafish lays up to 400 eggs, but no more than 100 fry survive to an adult state. Within a week, the female is again ready to spawn.

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.

See how to prepare an aquarium for danios.

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 process of reproduction 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.

Compatibility of fish in the same aquarium

Compatibility of aquarium fish - a very important issue for beginners and experienced razvodchiki. Each fish has an individual character, style of behavior, regardless of whether it is a herbivore or a predator. Some fish quickly eat plants and shrimp, others attack the fish themselves. Of course, there were cases when practically incompatible species coexisted in one reservoir.

Aquarium fish compatibility chart

To systematize this issue, you should familiarize yourself with the habitat conditions of each hydrobiont, and then decide who to share it with. Assess the degree of aggressiveness of each species, the water parameters that are acceptable for them, in which layers of the reservoir they usually swim. To ensure that your aquarium is filled with life, a table is provided that lists the compatibility of freshwater fish.

Watch the video about the compatibility of aquarium fish.

Angelfish

What fish are compatible with scalar? With them you can settle the representatives of non-aggressive species of medium size. These include:

  • Barbusses;
  • Corridors;
  • Danio;
  • Gourami;
  • Botsia;
  • Mollies;
  • Pecillia;
  • Plekostomusy;
  • Iris;
  • Rasbory;
  • Labeo;
  • The Swordsmen;
  • Tetras.

Between themselves, the scalars get along quite well in the conditions of a spacious reservoir, but from the age of the young stock they must live in a group of 4-8 fish, among which they choose a mate for life, as is typical of the Cichlids. With representatives of loach fish and shrimps are partially compatible, however, the risk of cohabitation in the common tank is high. Do not settle scalar with such fish:

  • Cockerels;
  • African and South American cichlids;
  • Goldfish;
  • Discussions
  • Guppy;
  • Carp koi;

Compatibility errors

  1. The main mistake is overpopulation of the reservoir. In cramped, but offended! Pisces do not understand what it means to give in to another; they inherited from their ancestors a tendency to fight for survival. A small territory, a lot of fellows, which means that there is not enough food for everyone. Therefore, it is not surprising if there were fights in a small nursery, and other traumatic cases.
  2. Incorrect zoning aquascap. Carefully read the rules of settlement of each pet: what plants are allowed, the substrate, the parameters of water.
  3. The content of large and small fish. Even a peaceful large cichlid can eat a small neighbor if it fits in her mouth.
  4. Ignoring the rules of spawning. During this period, the fish are more aggressive and sensitive. If they spawn in the general aquarium, they will be greatly disturbed, or they will eat eggs with fry. In order to avoid such cases, temporarily transfer the male and female to a separate spawn with acceptable conditions for reproduction.
  5. Wrong conditions of detention, when pets instead of pleasing the eye, gradually fade. Regular water changes, cleaning the tank, properly feeding - a guarantee of their health and a quiet life without conflict.
