What fish can live without oxygen and filter

Many fish intended for keeping and breeding in captivity, can not do without oxygen and filter. But not all! There are wonderful aquarium fish that freely do without an aerator. Name them. betta, or Betta Fish.

Aquarium Fish Without Oxygen

Instruction

1. The main advantage of these fighting fish is that they can live without oxygen and a filter. The fact is that Betta Fish breathe atmospheric air. Moreover, they don’t even like to live in an aquarium equipped with a filter, since such a “dwelling” is oversaturated with oxygen, and the current created by the compressor only scares them. Of course, one should not argue that Betta Fish can live well in three-liter jars, but the fact that they feel great in a small aquarium without any filtration and aeration is an indisputable fact!

2. That’s just the breeding of these fish can cause some difficulties, and not everyone wants to become a professional breeder. Many people generally keep Betta Fish for enjoying their beauty. Betta Fish is not whimsical about the rest of the service: they feel great in stale water, and also have no increased appetite. However, this does not mean that the water of Betta Fishm needs to be changed every six months and fed them once a week. Not!

3. Betta (or Betta Fish) aquarium fish are members of the labyrinth family. It is no coincidence that these fish have been dubbed "Betta Fish". The fact is that their color and combative fighting character reminds of beautiful and cocky cocks. For example, if you put two betta males in one aquarium, then a real cockfight with loose fins and tails can begin. If time does not separate the "fighters", then one of them will die.

4. In general, Betta Fish is descended from Vietnam, Indonesia and Thailand. There they live in warm and small reservoirs with stagnant and silted water. That is why an aerator for oxygenation of the aquarium with Betta Fish is not needed. Betta Fish have an oval body, elongated and slightly compressed at the sides. The length of the calf of males reaches 5 cm, and in females it is 4 cm. Dark stripes are arranged along or across the body of Betta Fish. Upper fin has a rounded shape. The bottom starts from the head and comes to the tail. The pectoral fins of Betta Fish have the correct pointed shape.

5. It is believed that the beauty and uniqueness of color is not equal to these fish. Betta Fish is full of colors, and their colors shimmer from red to pink, from pink to yellow, from yellow to orange, from orange to green, taking all sorts of shades. Especially bright color can be observed in males, arranging a "cock" fight. It is curious to watch the fish even when they inflate their gills in an excited state, forming a kind of bulging “collar” around their head.

Fish that can survive without oxygen in the aquarium

Aquarium Fish Without Oxygen

It’s no secret that oxygen is present in the aquarium in a dissolved form. Fish constantly consume O2 and emit carbon dioxide. When an aquarium is artificially highlighted, the fauna highlights it during photosynthesis. To ensure a comfortable life for the fish without additional aeration, it is necessary to choose the right plants and settle the optimal number of inhabitants.

The most common problem is considered an imbalance in the number of green spaces and fauna. In the event that plants are not able to cope with providing all residents with oxygen, aquarists are forced to resort to using special devices for aeration.

Aquarium Fish Without Oxygen

The presence of oxygen in water is the main criterion for the life of almost all aquatic organisms. Aquarium fish are demanding on the saturation of water O2. This indicator can be called one of the main in determining the chemical composition. Oxygen is essential for both fish and other creatures and plants. Each type of underwater inhabitants has its own requirements for aqua saturation. Some of them easily carry oxygen-poor water, others are sensitive to minor fluctuations. Few people know that an excess of oxygen can also have a detrimental effect on fish. How to determine the optimal indicator? If there is not enough oxygen, the growth of the fish slows down. This is primarily due to the wrong process of assimilation of food. Creating an ideal ecosystem, consider that in addition to fish, oxygen is consumed by other organisms from the aquarium: ciliates, intestinal cavities, mollusks, crustaceans, and even plants in the dark period. It is not difficult to guess that the more inhabitants, the more oxygen they consume.

It happens that the wrong organization leads to the death of the fish. In the process of oxygen deficiency, fish begin to choke due to accumulated carbon dioxide.

Causes of oxygen deficiency:

  • High density of inhabitants;
  • High salinity and temperature of aqua;
  • The consequences of improper treatment;
  • Alkalinity jump.

As a result of the increase in the thermometer, the processes occurring in the body of the fish are intensified. This leads to an increase in oxygen consumption. If the figures have crossed the mark of 28 degrees, then the fish begin to consume more O2 and emit a large amount of carbon dioxide, which leads to starvation and, if it is not urgent to react, then to the death of pets.

Lack of oxygen in a polluted aquarium is also dangerous. Various oxidation processes will occur in it, which will have a negative effect. It is very important to monitor compliance with the number of tailings and water quality. Try to provide pets with high-quality filtration.

It is worth saying about bacteria, which are an integral part of the underwater world. The increase in the number of inhabitants leads to a large amount of excrement, which leads to an increase in the ammonia content of the water. All wastes that are subject to mineralization are carefully treated with bacteria. Thus, the more organic elements, the more bacteria that also need oxygen. As a result, the circle closes. If bacteria and fungi are O2 deficient, then they begin to more slowly cope with the goal. Return balance in the ecosystem, you can only increase the supply of oxygen.

But there is another side to the coin. Thus, high oxygen saturation leads to an increase in pH. This situation is not welcome in the aquarium, because the difference in the water being replaced will be too global.

Pay special attention to the flora of your aquarium. Because plants are an amazing and very important part of creating the right microsphere. All plants produce oxygen during the day, but consume it at night! It is necessary to take into account and do not turn off the aerator at night.

What fish can survive without oxygen

On the Internet, more and more people are trying to find the answer to the question, what fish can live without air? However, the answer does not quite suit them. Find at least one living creature that does without oxygen is impossible. But there are some aquatic inhabitants who can survive without a system of aeration of water.

The difference between fish is that some of them calmly carry scant water and can breathe atmospheric gas. Due to their ability, they are considered the most enduring and unpretentious in the care. There are several types of such inhabitants, but, unfortunately, not all managed to adapt to aquarium life:

Aquarium Fish Without Oxygen

  • Aquarium catfish or loaches. These fish use intestinal respiration with atmospheric air. It happens quite simply. Catfish rises to the surface, swallows air and sinks to the bottom.
  • Labyrinth. They received their name because of the unique breathing apparatus, which is also called the gill labyrinth. The process of air absorption is similar to the previous option. The most popular aquarium representatives are: Betta Fish, gourami, lyaliumy, macropods.

However, one should not expect that these animals can live completely without air. They need it, therefore, in no case should one block access to the air from above.

Signs of lack of oxygen:

  • Fish rise to the upper layers;
  • After a couple of hours, the fish bulge the gills;
  • Decreased appetite;
  • The immune system suffers;
  • Growth slows down or death occurs in 2-4 days.

Death may not occur, but the fish experience constant discomfort and all life processes are slower, which affects the growth, color and behavior of the animal.

Thus, the fish can not live completely without oxygen, however, you can make your life easier by buying inhabitants who can breathe atmospheric air. But even with a small selection, you can gather the best representatives and create a unique reservoir where you can live, and at the same time not experience discomfort, fish and catfish.

Unpretentious aquarium fish

The beauty of the underwater world has always attracted people with its inaccessibility and mystery. That is why aquariums are so popular in city apartments and offices. It should be remembered that in a closed glass space there are living beings, completely dependent on their masters. Rough errors in feeding and caring for them can lead to very unpleasant consequences for swimming pets. For aquarists, especially beginners, the best solution will be unpretentious aquarium fish, for which it is easy and simple to care for.

Before buying fish, it is important to find out if it is a selective species. High survival and undemanding to the conditions of life is inherent only in natural forms (this applies to all living things). All developed, improved, crossed breeds do not differ by special vitality.

Successful breeding of fish depends on three indicators. the volume, temperature and chemical composition of water. Slightly more chlorine and iron in the water, just below 24 degrees heat in the aquarium. and problems with fractious individuals are provided.
Unpretentious same aquarium fish do not scare such trifles. We present to you several representatives of the water world who are ready to live in a three-liter jar and eat dry food. Even preschoolers will be able to care for them.

Guppy

Their survival rate was tested in space. they took the fish to see how they would behave under weightless conditions. Males guppies are small, very beautiful, especially during the mating season. Females are larger, but seemingly homely, always of the same silver-gray color.

These most unpretentious fish for aquariums belong to viviparous and breed quite quickly. If it is desirable to preserve the offspring, then the female is removed before giving birth. Otherwise, the fry can dine as neighbors in the aquarium, and their own parents.

For a comfortable habitat of guppies, the water in the aquarium should be separated from 18 to 28 degrees Celsius. Sudden temperature fluctuations are disastrous even for these, the most unpretentious aquarium fish. The compressor in the aquarium is desirable. Petsiliyevs feed on any plant, animal and dry food of suitable size.

Betta fish

The fish is very elegant, attracts attention with a rainbow color. Scales when tacking shimmers in different shades. The fish breathes atmospheric air, swimming up to the surface of the water, so it does not need a compressor. The food is picky.

Betta Fish is fed once a day, with live food or artificial flakes. Tap water must be defended before being added to an aquarium. By the time of spawning in the aquarium, it is desirable to place a bundle of Riccia. Out of his foam, an amorous father will make a nest. He also takes care of the fry.

The activity and colors of Betta Fish become more intense if in the next aquarium he notices something like himself. Two males in the same container can not be kept. they will fight until the weakest perish.

Danio

Aquarium Fish Without Oxygen

You can also pay attention to danios. Fast graceful fish very much decorate the aquarium with its various colors. Adults have a length of up to 6 cm. During spawning, it is better for the female to sit and watch her, otherwise she can swallow all her offspring. All types of danios easily get along with each other. They are fed with dried or live daphnia, cyclops, bloodworms.

Gourami

The fish has a silver-purple color with an orange border, during spawning it becomes striped. Before laying eggs, these unpretentious aquarium fish are very aggressive and malicious. The male gourami builds a nest of foam and twigs, he is caring for caviar and fry appearing. The number of fry in one litter is up to 500 individuals.

Juveniles do not require any care, feeding with their parents. In addition, young fish plucked pebbles and plants, clean the aquarium from the hydr. The length of the body of an adult gourami sometimes reaches 15 cm.

Macropods

These unpretentious fish for aquarium completely undemanding to the composition of water and food, but rather unsustainable. Especially they do not like telescopes and voilehvostov. they can tear off their fins and even damage their eyes. Each other, the macropods often do the same.

They are painted very interesting. the greenish torso is covered with crimson and green stripes, the fins are blue with red threads. After throwing eggs, the female should be transplanted to another aquarium. Caring father will take care of the eggs.

Somics

The variety of this type of aquarium fish is simply amazing. Smaragdaceous, golden, armored, leopard, elegant catfish. these are not all their names. Baleen fishes are called aquarium attendants. They will eat up all the drowned food at the bottom, clean the walls of the tank. True, at the same time, diligent workers raise such dregs, that it is impossible to do without a filter.

The fish eat all kinds of aquarium food. daphnia, bloodworms, tubule, dry artificial flakes. Sensitive to oxygen. Even with sufficient aeration, catfish often float to capture a bubble or another of air from the surface. The impetus to the mating season is a decrease in water temperature by 3-5 degrees, high-quality and abundant feeding. Before spawning, the female mouth cleans the area of ​​the glass wall and attaches eggs to it. Juveniles from the first days actively eat chopped moth and dust from any dry food.

Goldfish

Aquarium Fish Without Oxygen

Fantail, voilehvost, kamet. also the most unpretentious fish for the aquarium. They are undemanding to food and content, can starve for 2-3 days without much damage to themselves. Goldfish are distinguished by a beautiful color, unusual fins. In bright light, their colors become more expressive, making the aquarium a real work of natural art.

Betta Fish Fish: content, compatibility, reproduction, photo-video review

Amazingly beautiful, beautiful, unpretentious, bold. all these words can be applied to the aquarium fish Betta Fish. Aquarium Betta Fish have a bright variable color. Males, of almost all species of Betta Fish, have chic, veiled fins. And their content and breeding does not represent any complexity.

That is why Betta Fish is one of the most popular fish among beginners in the aquarium world, as well as among professionals, who contain beautiful breeding forms, exposing them to competitions.

To understand the beauty and temper of these fish, here is a literary description of the behavior of Betta Fish fish in nature from the book by I. Sheremetyev: “Along with the beautifully painted gouras, the greyish-green fish does not immediately strike the eye. Her body is 6 cm long, slightly compressed laterally, elongated. On the sides there are turbid longitudinal stripes with a greenish sheen.

And the same gray, inconspicuous fish approached the fish. And suddenly, as if something had flared and shone in a small body. The body and splayed fins have become emerald. The fish opens the gill covers and goes to meet the guest. Who is it. the female or rival. the male, the fish can determine only when he sees what the stranger will answer. The female is in front of a gorgeous male, obeying, placing fins. If she is not ready for spawning, she immediately flees. If two males meet, their intentions will be more serious than can be imagined. Mutual posing begins, demonstrating brightness, playing brilliance and fin sizes.

This can take several minutes, and sometimes an hour. If one fish turns out to be half the size of the second, then it leaves another area. But, if males are the same size, then the first blow will be made sooner or later! Within minutes after the start of the fight, the fins of a weaker male hang down in pieces, the gill covers are broken, the body is covered with bloody wounds. Fishes do not bite, and having opened their mouths so that their teeth stick out ahead, with all their might they drive dozens of needles into the body of an opponent. After some time, the opponent is defeated the male who won the fight, does not allow him to the air and the surface. The loser is killed! ”

Let us take a closer look at these amazing representatives of South Asian reservoirs.

Latin name: Betta splendens;

Russian name: Betta Fish, Siamese Betta Fish, Betta Fish, chicken, betta, fighting fish;

Order, suborder, family, subfamily, gender: Perciformes –Perciformes, Anabantoidei, Osphronemidae, Macropodusinae, Betta

Comfortable water temperature: 25-28 ° C.

"Acidity" Ph: It does not matter, but comfortable 6-8;

Stiffness dH: does not matter, but comfortable 5-15 °;

Aggressiveness: Betta fish Betta relatively peaceful fish. they can not be called predators. However, they have a strong intraspecific aggression and territoriality. Keep two males in a small aquarium is not possible. The dominant male will surely kill the weaker. Two or more males can be maintained only in large and wide aquariums, while fights for territory and females still cannot be avoided. In addition, males often show aggression and to a “disliked” female during spawning.

The complexity of the content: easy;

Compatibility fish Betta Fish: in addition to the previously mentioned intraspecific aggression, the aggression of fish extends to all small, clumsy and voile fish. Therefore, you can keep them, only nimble, active fish that will be similar in size. As a recommendation, it is possible to advise in the neighbors of Betta Fish: corridors (speckled catfish), danios, molines, swordtails, other nimble platies, tetras.

Betta Fish is not compatible with cichlids, the family of goldfish, other labyrinth fish are not desirable. Not compatible with snails, they eat small snails, and large ones cut off their whiskers.

In addition, when combining fish you should always take into account the similarity of conditions and water parameters, for more information on the compatibility of aquarium fish, see HERE!

How many live: Betta Fish fish are not aquarium long-livers, their age is short. only 3 years. Find out how much other fish live HERE!

The minimum amount of aquarium for fish Betta Fish

The question of the volume of the aquarium for these fighting fish is a separate topic.

Aquarium Fish Without Oxygen

Yes, of course, Betta Fish is a hardy fish, in natural habitat they live in muddy, silted, oxygen-free rice fields. But this does not mean that they can be kept in a small glass with water. Firstly, because the conditions of keeping of any animal should be as close as possible to the natural living conditions. Monkeys must jump in trees, birds fly, and fish swim. When the Betta Fish fish just hangs in a glass, dropping the fins. this is actually a sad sight. Secondly, in the cup, vase and other small vessels there is no biobalance at all. In the rice field, for example, various biochemical processes take place that purify water from various poisons (ammonia, nitrites and nitrates), these processes are absent in a glass with water, the poisons accumulate, the immunity of the fish weakens and it dies. Biological equilibrium in artificial conditions can be achieved only in spacious aquariums, and the more, the better.

So, the minimum volume of the aquarium (decorative vase, etc.) for Betta Fish should be 3 liters. To call such a vessel an aquarium is difficult in all senses, and therefore, if we talk about creating a full-fledged aquarium, the minimum volume for one individual should be 5-10 liters. In such an aquarium, you can put a mini-filter, such an aquarium can be beautifully — naturally, you can plant aquarium plants, adjust the biobalance, and taking care of such a reservoir is much easier than washing the “pot” weekly, while delivering great stress to the fish. A good volume for a pair of Bette is considered an aquarium from 20-30l.

About how much you can keep the fish in the X aquarium, see HERE (at the bottom of the article there are links to aquariums of all volumes).

Requirements for the care and maintenance of the fish Betta Fish

From the above, we can conclude that in one, a small aquarium, you can contain only one male Betta Fish. If the aquarium is large. from 100l. You can try to plant the second male or make transparent partitions in the aquarium, for example from plexiglass, pre-drilled holes in them to circulate the water in the aquarium.

Aquarium Fish Without Oxygen

In addition, I advocate the creation of a natural. natural environment in an aquarium. The aquarium can and should be decorated with stones, grottoes, snags, as well as living aquarium plants. The lighting should not be very bright, preferably the presence of filtering. The aquarium itself should not be filled with water to the brim, you need to leave 7-10 cm and be sure to cover the aquarium. All labyrinth fish and Betta Fish in particular breathe atmospheric air, swallowing it from the surface of the water. In the absence of airspace or access to the surface of the water, the fish will suffocate. The lid is needed to ensure that air from the surface of the water swallowed by Betta Fish is not too cold.

An aquarium with Betta Fish can be equipped with artificial plants, but still, if you have the opportunity, purchase live aquarium plants. With live plants, the aquarium looks more natural, the plants themselves contribute to biological balance, and the males can also use them for spawning and creating a foamy nest. From unpretentious plants for Betta Fish we can recommend: vallisneria, rogolini, cryptocorynes, other not complex plants.

Aquarium Fish Without Oxygen

Feeding and diet Betta Fish: they are not whimsical in food, they are happy to eat both dry and live food (Artemia, bloodworm, etc.). Betta Fish eat any branded dry food, however, advanced aquarium brands have developed special for them. individual food that is best suited. Feeding aquarium fish should be correct: balanced, varied. 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.

In nature, live: Southeast Asia: Indonesia, Thailand, Cambodia, Malaysia, Vietnam. They live in stagnant, oxygen-free waters. puddles, ditches, rice fields.

Description: Very beautiful fish, its veil tail and fins just fascinate. The color of the fish is different. The most common ink color with a reddish tint. Males are colored much brighter, fins are longer than those of females. The size of the fish is 5-10 cm. The body is laterally compressed, elongated, oval. They have cycloid scales, pointed pectoral fins, upper and tail fin of a rounded shape, the lower fin originates from the head and ends at the base of the tail.

The history of fish Betta Fish

Aquarium Fish Without Oxygen

The first mention of the fish dates from the beginning of the nineteenth century, it was then that the people of Siam paid attention to these small, but lively and aggressive fish. Next, the Siamese began to cross wild individuals Betta and got a new kind of fish, calling it "biting fish." A couple of copies of these "pieces" in 1840. King of Siam handed over to Dr. Theodor Cantor, who in 1849 gave them the name Macropodus pugnax. After 60 years, the British ichthyologist Charles Tate Regan renamed them “The Beton Fish”, arguing that the Macropodus pugnax species already exists in nature.

It is known that the fish Betta Fish appeared in Paris in 1892, in Germany in 1896, and in 1910 appeared in the United States with Frank Locke from San Francisco, California. Through the selection of these fish, he received a "new" fish, calling it Betta Cambodia. one of the first color variations of Betta Splendens. The history of the appearance of Bette in Russia is not truly known. There are several versions. The first is associated with aquarist VM. Desnitsky, who allegedly in 1896. It brought exotic species of fish and plants from Singapore, but it is not known for certain whether there were any Betta Fish among them. The second version says that the aquarist V.S. Melnikov approximately in the same period spread a number of labyrinth fishes in Russia. By the way, a competition for the best fighting fish was established in his honor. And the latest version says that the fighting fish were brought in by the Frenchman Seysel, and all descendants from Russia and Europe went from his fish.

Bette species and Betta Fish breeding forms

The first thing I want to say is that the fish Betta Fish (Betta splendens) is one of the Bett species. Bette species should be distinguished from Betta splendens breeding forms. On the Internet, everywhere, the breeding forms of Betta Fish are given as species, which is not correct!

So, Bette’s species include: Betta picta (Betta picta), Betta striped (Betta taeniata Regan), Betta smaragdovaya (Betta smaragdina Ladiges), Betta unimakulata (Betta unimaculata), Betta black, she’s also Betta Fish, dwarf she Betta Fish black (Betta imbeIIis Ladiges), Betta Fish (Betta splendes).

Reproduction and breeding aquarium fish Betta Fish

It is much more difficult to find a good pair of producers than to spawn itself. And if we talk about the breeding of Betta Fish, the question of the selection of parents arises squarely.

General information about spawning and breeding Betta Fish.

Sexual maturity fish Betta Fish reach 3-4 months. From this period they can begin to breed.

Sex differences in fish are pronounced. males are larger than females, their fins are much larger and males are, as a rule, brighter than females. In addition, the female ready to spawn can be distinguished by the white “grain”, “star” in front of the anal fin. this is the egg-deposit, as well as the large abdomen.

On photo male and female fish Betta Fish

An aquarium for spawning may not be large from 10 liters, the water level in which should be 10-15 cm. A spawning aquarium should not have soil and is equipped only with shelters for the female, for example, with crown, as well as with small bushes of perististoistnye plants, for example, with roetail. You also need to use plants that float on the surface of the water: duckweed, piste, water-colored plant These plants are used by the male in the construction of the so-called "foam nest".

The temperature in the spawning tank should be in the range of 26-30 degrees Celsius. Different sources, write different data on the temperature regime for spawning Bette. Taking into account the analysis, I think that 28 degrees is the norm. This temperature is optimal and makes it possible to increase it by a couple of degrees, thereby stimulating spawning.

Spawning and soft water is used for spawning aquariums. Soft water is an incentive to spawn. You can soften the water aquarium chemistry. preparations containing peat, and other methods. In addition, in the spawning aquarium is recommended to throw a leaf of almonds (see Herbal medicine for fish and aquarium).

Before spawning, the producers sit for a couple of weeks, and are abundantly fed with live food. After spawning in the aquarium, the first place the male, which begins to settle. As soon as he begins to build a foam nest, a female with caviar is brought to him. The presence of calf in the female can be determined by the rounded abdomen.

If the spawning process does not start or the male does not pay attention to the female, the spawning should be stimulated: by softening the water or replacing the water with fresh water, raising the temperature by 2-3 degrees. If after these manipulations, spawning does not begin, you can try to plant another male in the presence of the male (if you have one).

But, usually, the above-described problems with breeding Betta Fish do not arise, by evening the male already finally builds a nest, and in a day the caviar matures in it.

IMPORTANT. Stimulating fish in a spawning aquarium with live food is prohibited. At the time the producers are in spawning, they are not fed at all in order to avoid contamination and unwanted fungi and bacteria.

The process of spawning itself is very interesting. It begins with the fact that the male swims up to the female, hugs her and squeezes 2-5 eggs out of her. Eggs begin to fall to the bottom, the male quickly collects them in his mouth and places them in a foam nest. This “hug and spin” process is repeated several times.

A visual indication that the spawning is over is the male’s circling over the foam nest and the female’s seat in the shelter. As soon as this moment has arrived, the female is removed, since in the eyes of the male she begins to carry a threat to the offspring, which is why he can kill her. The deposited female is abundantly fed. Further, all the care of the clutch and the offspring takes the father! The main thing at this moment is not to disturb him. After one day, the larvae will appear, and after another day the yolk bladder will dissolve in the larvae and they will begin to swim.

You can remove the happy “father” and start feeding the fry with live dust by infusoria or, for example, as some members of our site do it with melted water from Artemia frost. You can also try dry fish "baby food", for example, Sulfur Micron. Such feeds are either diluted in a bowl and the resulting suspension is poured into the spawning unit, or they take the feed at the tip of a finger and, grinding it in water, feed the young fish. Food in the aquarium should be present constantly. When feeding with live food (ciliates), water does not change, and when feeding with dry food, 80% of water is replaced daily in order to avoid contamination and mortality of the young. To maintain cleanliness in the aquarium, you can place snails ampoule or coils.

In the future, Betta Fish juveniles gradually (in 3-4 days) are transferred to larger feeds, starting with Artemia nauplii, etc. After about two weeks, you can begin to try to give "adult" feed.

Labirint, or creeping (Latin. Anabantoidei, outdated name. Labyrinthici), is a suborder of perciformal fishes, which have a labyrinth organ, which allows fish to additionally breathe atmospheric oxygen. Predominantly freshwater fish with intermittent African-Asian distribution; Missing in Madagascar. Possess a wide variety of morphological and behavioral signs.
Gourami, macropods, swordtails, lyalius and many other famous aquarium fish.

Without oxygen in our area. hardly any. Any water has to be heated, and so that warm water does not collect at the top of the aquarium, air blowing is required to mix the water. Therefore, in the winter, even in a fully overgrown aquarium, where there is enough oxygen, the macropods and cardinals have to switch on the compressor at the same time as the heater.

Elena Gabrielyan

It is undesirable to keep fish without a filter, since waste and food decomposing at the bottom will spoil the water and it will have to be changed frequently in a small aquarium, this will solve the problem with a filter, and labyrinth fish live without oxygen: Betta Fish, Gourami, Lyalius

Alexander Komendantov

All fish are aerobic, no one can live without oxygen. Without aeration is another matter, the question of the volume of the aquarium. If a large aquarium. any. The labyrinth, lungfish, anabass, jumpers, and many catfish can live in a minimum amount without aeration — they are all able to breathe atmospheric air. If you put a heating pad on the bottom along the back wall. there will be no problems with water stratification.

Any. The main thing that there was no resettlement, the calculation of 3 l on the fish, guppies do not count, the labyrinth will take less. Flush live food, water will not need a clean filter. In the water or silver spoon or coin. Greetings from St. Petersburg.

What aquarium fish can be kept without oxygen?

If you mean oxygen in water, and not oxygen in general, then these are any representatives of the labyrinth family.
Labyrinth fish are known for their ability to breathe atmospheric air. For these purposes, they have a special organ called the labyrinth (this rgan gave the second name to the Belontium family. labyrinth). The labyrinth is located directly above the gills, in small grooves on both sides of the head. Fish swallow atmospheric air near the surface of the water and place it in the spongy chambers of the maze, the walls of which are pierced with a network of blood vessels. This additional breathing is vital for them. if these aquarium fish are denied access to the surface (for example, the cover glass touches the surface of the water), then they may die.
Scientists subdivide the labyrinths into four families: anabasic (Anabantidae) with genera: creepers (Anabas), sandelia (Sandelia), and ctenopomes (Ctenopoma); Macropod (Belontiidae) with childbirth: Betta (Betta), Belontia (Belontia), Ctenops (Ctenops), Colises (Colisa), Malpulluta (Malpulluta), Parosphronems (Parosphronemus), Pseudosphronems (Pseudosphronemus), Sphyshim, Sphishem, Sphischys, Pseudosphras (Pseudosphs) ), trichopsis (trichopsis) and trichopters (Trishopterus); chelostomy, which includes one genus Helostoma (Helostoma); and. real gourami, also with the same genus Osphronemus.

The most common aquarium fish, labyrinth family is Gourami marble or gourami ordinary
