How much is a small aquarium


What kind of fish to settle 10 liter aquarium?

A small aquarium is a tank with parameters of 20x40 cm and less (a nano aquarium) in which small ornamental fish can be placed. The volume of such containers can be from 10 to 20 cubic liters, so they are suitable for the installation of decorations and equipment. In a small aquarium you need to put lighting, plant plants, decor, do not forget about the filter and compressor. That is, a small aquarium should not differ in functionality from a spacious one.

How to set the balance in the mini tank?

Care of a small aquarium, on the one hand, easy, and on the other, takes the hassle. Choose a mini tank rectangular, with straight and smooth walls. It is convenient to clean them with a scraper, to maintain. If the tank is round, then it will be inconvenient to reach its corners, it is difficult to wash. A 10-liter aquarium pollutes faster than a 50-100-liter aquarium. Water changes will have to be done more often, as well as comprehensive cleaning, which is not useful for the biobalance of the aquatic environment and the health of the fish.

The main disadvantage of mini tanks is a small amount of water. It does not fit a lot of fish. There you can settle 1-2 fish, and no more. In a large aquarium, water changes are not strongly felt, in a small one this is a great stress. Any changes in the biological balance: fish death, overfeeding, pollution immediately affect the aquatic environment. The only thing that can be done is to adjust the water parameters in time, feed the fish gently, clean the bottom.

See how the ground siphon in the nano aquarium.

To care for a small aquarium should be the same as for a large one. Once a week you need to change 10-15% of water, if necessary. So that the fish do not have stress, do not replace the water completely, try to add it in small portions. The ideal aquarium filter for such a tank is a pump with an internal sponge. The sponge cannot be washed out under running water, otherwise all beneficial bacteria participating in the nitrogen cycle will die.

If you choose the smallest reservoir, then it will be almost impossible to install plants and decorations. Some skillfully planted even in 3-liter jars of dwarf plants, but it is inconvenient to take care of them. In the 10 liter tank there is the possibility to hold a dwarf anubias, a dwarf arrowhead, an echinodorus "dwarf amazon", a dwarf cryptocoryne. Plants for a small aquarium are able to control the level of nitrite, nitrate and ammonia, create shelters for fish. Make sure that the aquarium was the ground. Choose a substrate treated, clean, without paint. Remember that using a regular scraper to clean aquariums of minimal size is very difficult from the layer of plaque.

Now about feeding. As you know, overfeeding harms not only the health of the fish, but also adversely affects the quality of water. All uneaten decays, turning into harmful impurities and bacteria. Decay products are deposited on the bottom and reservoir machines, disturbing the stability of the biological environment. Fish should be fed, hunger is also not an option. Once a week, arrange fasting days for fish. Add food to 4-6 grains, which pet is swallowed by force. What is not eaten, you need to remove the gauze net.

Let's for fish that live in a small 10-20-liter nursery as much feed as they eat in 2-6 minutes. Flakes, live food, sinking granules fit. They sink slowly and do not pollute the environment. If you live on bottom catfish, they will eat everything on their own. Fish can be fed to their usual high-grade food, without disturbing the diet. It is important to clean everything in time.

Which fish is suitable for settling in a mini aquarium?

What kind of fish can you keep in mini aquariums? In a small 10-20 liter tank you need to settle pets with miniature body size. Fish 2-6 centimeters in length will carry such a volume of water. But remember that even small fish want to swim in a spacious environment. They can not be kept in containers that will restrict movement. Territorial and aggressive fish cannot be accommodated in mini aquariums. Which do not need to settle in a 10-liter aquariums? These are swordtails, barbus averages, cichlids, gourami, danios. They have an active and energetic disposition, they need more space for shelter.

In the aquarium of 10-20 liters, you can settle small barbs, pseudomogil gertrudy, rice fish, cherry barbus, rasbor, erythrosalonus, neon, tetra Amanda. Also there you can keep such fish and shrimp: catfish ottsinklyus, corridor, shrimp amano, cherry shrimp, copper tetra. A representative of the genus Pecilia, viviparous fishes get along well in mini tanks.

You need to buy breeds of fish with a strong immunity, that is, not actually thoroughbred, but hybrids. If you do not have the opportunity to buy a spacious "house" for your small pet, you need to buy a small aquarium with a capacity of 10 liters. There are also often settled well-known Siamese cockerels. The cockerel can live alone, does not get along with relatives, this is after all a fighting fish.

Big chores with a little underwater miracle.

Mini aquarium

There are many types of aquariums. They are distinguished by purpose, shape and volume. Well-designed freshwater and saltwater aquariums, decorative aquariums and aquariums for breeding, aquariums, paintings and giant aquariums built into the walls, large and small aquariums are amazing. From all this variety, you can select a mini-aquarium. It may have a different shape and volume of not more than 20 liters.

The mini-aquarium fits perfectly into any interior and takes up little space: you can use the fish’s habitat as an original coffee table or put a piece of wildlife on your desktop with a bit of imagination. Very often you can find a similar aquarium, decorated in the form of a giant glass. The latter option is often used when decorating a cafe.

The influence of the aquarium on the nervous system, and on the whole body is positive. The eyes and the brain rest from the routine, painstaking work when you observe the uniform movement of the fish in a small aquarium.

Care of a mini aquarium

As for the maintenance of the aquarium of small size, here you can get under the influence of stereotypes. Often, parents buy aquariums for their children, considering that a small aquarium is easier to clean than a large one. Rather, the "underwater world" of a small size is subject to temperature changes and requires frequent water changes. If water is rarely changed, the waste products of fish begin to accumulate on the walls and it will be rather difficult to clean the container with your hands. In addition, the slightest excess feed, stale at the bottom of such an aquarium, instantly spoils the water and shifts the biological equilibrium.

But if you decide to start a small aquarium, get it "fully loaded". Specialists will select all the necessary equipment for lighting, water filtration and water heating. And, despite the equipment, place the aquarium in a room whose temperature is constant. With such a small amount of water, a drop of even 1-2 degrees negatively affects the fish. When feeding fish, give off a small amount of food so that after feeding there will be no leftovers. Remove excess feed immediately.

When caring for an aquarium, you will have to carry out frequent water changes, until the bacteria stabilize their numbers in the filter. Bacteria convert waste decomposition products into safe substances. A stock of settled water should always be at your disposal. Water in the aquarium should be changed every three to four days, replacing at least a quarter of the volume of water in a small aquarium.

To prevent algae, an aquarium should not be placed close to the window. Direct sunlight should not fall on it, and the duration of the active daylight should be smoothly increased from six hours immediately after the arrangement of the aquarium to ten hours by the time the biological equilibrium is stabilized.

The smallest aquarium in the world - video.

Separately, I would like to mention this model as a small round aquarium. This kind of aquariums can not be considered successful:

  • first, curved glass has the effect of a lens and distorts the outlines of fish,
  • secondly, the fish themselves see the world in a similar aquarium blurry (many aquarists are sure that this negatively affects their health),
  • thirdly, to clean the rounded glass is difficult, the standard scraper is not suitable for this procedure.

Fish for a small aquarium

Creating and maintaining biological balance - the optimal ratio of plants, decor and fish for a small aquarium is quite a laborious job. Residents of the aquarium should feel comfortable in a small space. To do this, do not overload the small aquarium inhabitants.

Fish for a small aquarium is chosen depending on their size and nature. Small fish with a calm, peaceful nature are preferable. You can combine several species of fish with the same content requirements or create ideal conditions for one breed.


Guppies, small golden and cherry barbs, gourami, glowing tetras are fish for a small aquarium. The aquarium looks good with one goldfish or a cockerel. Also in such a reservoir, you can settle danios or neons.

Keep track of the size of your pets. With good care, the fish grow in a small aquarium, and it becomes crowded. Catch large fish in large domestic reservoirs and replace them with young.

Making a small aquarium

There are many forms of a small aquarium: a cube, a glass, a trapezium, hexagons, etc. The smallest aquarium in the world, for example, has a rectangular shape, which only emphasizes its uniqueness. If you still choose a small round aquarium, remember that externally round and rectangular aquariums may seem the same size, but the round aquarium always has a smaller volume. Choose decorative elements for a small round aquarium according to its volume, small snags and stones, which can also be used as a foundation for fastening plants. For decoration of small aquariums most often use moss (small pieces) or Hemianthus, and from plants - Anublas, Microsorum and Vesicularia.

In the case of small aquariums, a good solution would be to completely abandon the fish and populate the pond with shrimp. The aquarium with young ampouleries will also look impressive.

A mini-aquarium, like a spark in the dark, will illuminate your apartment with natural peace and beauty.

Sea Aquarium in your home! How to start and how much?

Sea Aquarium in your home! Where to begin?

Seawater aquarium can be a central element of the interior of your home or workplace.

But the question is:

What can you do to buy and install a marine aquarium?

How much time and effort will take further care of the marine aquarium?

How do marine aquariums differ from each other, and which one is best suited for a particular interior?

Not every aquarist keen on his business will be able to thoroughly and clearly answer such questions to you, let alone those who are just beginning to think about such a purchase. We will try to present in this article the main and secondary points related to the purchase and subsequent maintenance of the aquarium. Go.

In the aquarium market there are a considerable number of manufacturers. Each of them practices its own marketing policy and has certain advantages over competitors. German aquariums AquaMedic, "Israelis" RedSea, the Japanese company ADA, the Chinese brand Anubias - by clicking on the link AQUARIUMS, You will note more than a dozen other companies and countries where these firms are located.

For an example that will help us estimate the estimated cost of the entire list of accessories and materials that you will need to fully maintain your piece of the sea, take the inexpensive 30-liter AQUAEL NanoReef aquarium from Poland.

We calculate the total estimate and the cost of each list separately.



List # 1

List # 2

List # 3








Now let's analyze the main points of our lists in more detail:

Salt for marine aquarium

In no case can you use ordinary cooking or cosmetic salts for aquariums. Harmless to the inhabitants of your aquarium will only sea salt, sold in specialized stores. The most versatile and high-quality options can be the products of the companies Red Sea and Tropic Marin, its composition is perfect even for aquariums, recreating the ecosystems of coral reefs.

Instruments for measuring and monitoring parameters in the marine aquarium

Most inhabitants of saltwater aquariums can only feel comfortably in water with certain properties. Temperature, density, salinity, oxygen saturation and many other parameters of aquarium water can be monitored and controlled using a specific set of measuring equipment. Consider several types of such equipment a little closer.

Refractometer - optical device, at the professional level, measuring salinity and density of water. He assesses the degree of refraction of a ray of light passing through a tiny, a few drops of water sample. And based on how strong the refraction (refraction) of light in the sample is, it gives the exact value of the density of water, as well as the percentage of salts contained in it.

Hydrometer - a kind of high-precision thermometer (although it does not measure the temperature). So high-precision that such devices are often used in laboratory research. To determine the salinity of the water, the areometer requires a strictly specified water temperature - 25 ° C. You simply immerse the device in a filled aquarium and determine its salinity level in a matter of seconds. On the scale of each hydrometer there is a green zone, within which salinity is considered normal for aquarium living creatures.

Hydrometer - is a device that measures the salinity and density of water. It also needs a liquid of a certain temperature (25 ° C), at which accurate data on the salinity of sea water are displayed on a large and convenient scale of the hygrometer.

Living stones for marine aquarium

live rocks for saltwater aquarium

live rocks for saltwater aquarium

Living stones are a very important component of the marine ecosystem. Actually, why are these stones called "alive"? Each such stone is in fact not a real stone. In most cases, it is a piece of the surface of a coral reef and has a porous structure, becoming a large apartment building for a great variety of microscopic algae and animal organisms. They pass seawater through themselves, converting potential pollutants (nitrates, phosphates, various organic acids, etc.) into chemically and biologically neutral compounds. The water becomes cleaner, safer and healthier for fish and other inhabitants of the aquarium. Этому также способствует и химический состав живых камней, обогащающий воду ионами кальция, магния, гидрокарбонат-ионами и другими минеральными веществами. Такие камни могут, как находиться непосредственно на аквариумном дне (некоторые из них выглядят чертовски эффектно), так и лежать в биофильтре. А со временем населяющие их микроорганизмы будут постепенно покидать свои родные каменные апартаменты, находя себе новые уголки в крошечных полостях грунта или декораций, не прекращая нести свою благодетельную фильтрующую миссию.

Live stones small / fight.

Exactly the same stones, only crushed to the state of a large crumb. They are used in the cavities of aquarium filters, where they become an excellent replacement for the sponge located there by default. Unlike standard sponges, small live stones are a much more powerful barrier against harmful substances such as nitrates.

Live sand for marine aquarium

live sand for marine aquarium

Living sand has in its composition, as an inorganic substrate, and tiny forms of living organisms - invertebrates and bacteria. A 3-6 cm layer of sand at the bottom of the aquarium will carry both an aesthetic function, creating a feeling of a real seabed, as well as a whole range of practical functions that benefit the whole aquarium.

- Many fish and other inhabitants of the aquarium use living sand as an abundant and permanent source of food - living organisms contained in it reproduce at an enviable rate, maintaining a stable amount of organic matter in the sand. Some other fish swallow sand in order to improve digestion.

- Living sand helps in maintaining the balance of chemicals in the water. Its alkaline structure has a positive effect on the pH level, and new calcium and strontium ions, important for many inhabitants of the aquarium, are continuously released into the water.

- Of course, living sand itself is home to many biological species - starfish, snaketails, bottom digging fishes, crustaceans. They will not be able to live in an aquarium without a sufficient layer of live sand at its bottom.

Like living stones, sand also has the ability to “age” over time. Experts recommend either to completely change it, or just periodically fill up some fresh live sand to the bottom. It is impossible to keep the tank with live sand in the open state for more than a day, otherwise it could end in death for the organisms inhabiting it.

Summing up, we can conclude that creating a piece of the sea at home is not at all difficult and relatively budget-friendly. Completely ready system on 30 liters, will leave to you in 36.550 rubles.

How many years will live cock in the aquarium?

The betta siamese betta splendens are very popular pets that live in an aquarium. For the first time having settled this fish, many people have a question: "How many cockerel fish live?" The average life expectancy is 2-4 years with proper care. If you have created proper conditions for your pet, then at home he will live as long as possible. To achieve this result, you must follow the rules for the purchase and maintenance of fish.

How to choose a healthy cock in the store?

Your cockerel will live longer if initially purchased from a good seller. When you notice that the fish lives in quality conditions, moves well, eats, it has a beautiful appearance - it means that you can settle at home. First of all, pay attention to the activity of the fish in the aquarium, the state of the scales and fins, its general physical condition.

Buy a young fish. The sooner she gets used to your tank, the more comfortable she will be there. The youngsters adapt more quickly to new conditions of life. In young males, the fins are shorter than in the mature ones, and in the young the body size is several centimeters smaller.

Look at the young male Blue / Red Dragon Halfmoon Betta.

Estimate the volume and condition of the water in which the not yet purchased fish lives. If you notice a cloud, dirt, substrate of unknown origin, wait a little with the purchase. Water should be clean, clear, slightly yellowish shade is allowed.

Look at the other fish that live in the same tank with the fish you like. Is it a little tight day? How do they move, feed, their external condition? The Siamese cockerels are fighters, and a long settlement in a species aquarium will destroy them all. If each fish lives separately, in good conditions - this is a big plus.

Do not buy two Betta splendens at once. If you lodge newcomers in a common tank, they quickly harm each other. Buy one pet, put him in a 2-week quarantine, look at his condition. When he gets used to the new environment, you can populate it in a pre-prepared aquarium. After a few months, you can add neighbors to it, but given the nature of the character, this is a big risk.

How to help the fish live longer?

  1. Set up the aquarium correctly, wait until it is established biological balance. Let it be a rectangular tank with a volume of 50-100 liters. Small, round containers will not allow the fish to move, it will be uncomfortable and boring. In the spacious reservoir there is an opportunity to create an amazing aquascape that resembles a natural biotope. Use a good filter to quickly deal with biological stress.
  2. Let plants and algae be in your tank. In the most convenient for cockerels tanks there is a lot of vegetation, they are provided to ensure that there is enough oxygen in the water, and it remains clean. Buy plants from trusted vendors so that they are healthy and treated for parasites.
  3. Maintain the temperature in the aquarium. Adjust it with a water thermometer. The cockerel is a tropical fish, which is used to warm water: the temperature is 26-29 ° C. Use 50W heaters.

    See how to keep a cockerel fish.

  4. The life of the fish will extend the correct, balanced feeding. In the aquarium, the fish will only eat what they give it, so choose several types of feed. Live, frozen, dry, artificial - the cockerel is omnivorous. However, do not overfeed, try to give suitable, proven feed. Clean uneaten food residues in time.
  5. Be attentive to your pet - watch him, play with him. Teach him new tricks to help him interact with you.

  6. Do not try to provoke the fish to aggression. Sometimes you can put a mirror in the aquarium, but for a short time. Betta's cockerel is a real fighter, so he should not be in constant rage. Do not put decorations or stones on the bottom of the tank that could damage the quality of the water. Dyes, water softeners are not always appropriate.
  7. Make timely water changes and clean your aquarium. There is a perception that cockerels are very hardy fish, but this is not entirely true. Dirty water provokes illness, and even the death of a pet. Sharp changes in water parameters are also destructive for a living being.
  8. Let the fish spawn. Let the roosters not have good parents, but the lack of reproduction adversely affects their health. In the female, the calf lag forms cysts with which it is difficult for her to live. Males become more lethargic and live less.

  9. Make sure the lid in the aquarium is slightly open. Like labyrinth fish, cockerels must breathe more and atmospheric air. Ensure that the air and water temperatures match.



A round aquarium can be a significant part of the interior room. Quite a lot of aquarists admitted that they acquired a round flask so that a luxurious goldfish floated in it. Of course, in reality, the aquarium turned out quite different. The idea did not appear because of the love of nature, but from the search for a spectacular interior solution.

The location of a round aquarium in a room involves the choice of an open space: on a table, on a separate stand, or mounted on a wall. A semicircular aquarium can also be fixed on the wall. The shape of the tank gives the underwater world an interesting look. From different angles of view, aquatic inhabitants and vegetation will look different.

How to make it?

Making a round aquarium requires a special approach. Aquarium is not only an interior object. Its main function is to create conditions for the life of aquatic creatures. Therefore, it is necessary to purchase special equipment for a round aquarium. Without it, the fish will not survive.

It is necessary to place a compressor, heater, filter in the flask, to provide lighting. Conventional devices will not work, they will be too allocated in the water space. When buying, you should choose models with the indication “for a round aquarium”. The shape and dimensions allow them to be placed neatly so as to spoil the appearance least of all.

Pebbles are scattered at the bottom and plants are rooted in them. Equipment for a round aquarium is hidden by plant shoots. It is advisable to choose such aquatic plants so that they do not hide the main inhabitants with their bizarre appearance. And pay special attention to the shape and size of the stones. Remember, in a round aquarium, all the details look more prominent. Therefore, any defect is immediately noticeable.


The specific shape and small volume do not allow creating thematic landscapes with large-scale decoration in the form of fragments of a ship or ruins of a castle. However, when designing a round aquarium, you can use other design techniques. For example, among the stones you can place a miniature model of a chest from a pirate ship. Or lay out a few fragments of ethnic pottery.

The main principle on which the decor of the aquarium space of this form is based is minimalism. Otherwise, for all the elements you will not be able to see the underwater inhabitants.

The lid for a round aquarium performs several functions: it prevents fish from jumping out, getting into unusual objects, protects animals from children and cats, and also serves as a place for fixing the lights. Therefore, it is better to purchase an aquarium immediately with a lid than to search for the desired model. The cover for a round aquarium can be purchased only in specialized stores. It is more difficult to find a cover only for a semicircular aquarium.


the neons

In a round container, light is refracted peculiar. According to the widespread opinion among aquarists, not all fish are able to survive in such conditions. Firstly, living beings may experience stress due to distortions of the surrounding reality, and secondly, it shortens the lifespan for nerve fish. Although the main limiter is the amount of space. Fish for a round aquarium fit only small size. Be sure to put here a little catfish, so that it clears the glass from green scurf. Neons, males, and lilies will feel great in the water. Small-sized goldfish grow badly and often get sick. The number of small fish should be maintained at the same level. Before you run neons here, you must make calculations: the number is determined by the volume of the aquarium. Overpopulation will immediately affect the health of the fish and the general appearance of the artificial reservoir. The power of equipment for the aquarium is selected in accordance with the requests of a particular group of fish.

It is better if the fish for a round aquarium will be bright, visible. For example, some species of guppy.

Aquarium Care

Cleaning a round aquarium has its own specifics. Since its volume is low, about 20% of water should be replaced every week. The water is poured or filtered.

Particular attention - cleaning glasses. Experienced aquarists are advised to plant inside the animal that eats algae: catfish, snails. Glass bending does not allow the use of ordinary brushes. Therefore, craftsmen have adapted to clean up the raid with a piece of women's nylon pantyhose.

To remove fish excrement, it is necessary to use a siphon, about once every two months. In a round aquarium, the bottom shape eliminates the creation of "dead zones", so the garbage is removed especially well. Part of it accumulates in the biofilter, and the rest
removed by siphon.

All devices (filter, compressor, heater) and plants are washed as they accumulate various contaminants. The main thing is to do all the work on time. Then a spherical aquarium will delight those around you with its appearance.

Aquarium fish somiki: corridors and the smallest catfish

Common catfish, speckled, corridor - all these names refer to the representatives of the kallichtovy family, or armored somikov. This species inhabits freshwater bodies with dense vegetation of Brazil, Paraguay, Argentina and other countries of South America. Many of the representatives of the corridor view have taken a firm place among experienced aquarists and amateurs due to their interesting behavior, unique appearance and unique coloristics.

Somiki corridors - aquarists' favorites

It is not possible to list all representatives of somik-corridors in one article, therefore we focus only on those who have gained great popularity among aquarists.

Orange dark

Size: up to 5 cm. Water for the maintenance of this species of catfish should be soft with low acidity, with a constant temperature of 25 to 27 ° C. To obtain the maximum saturation of the color of the fish, most of the aquarium should be planted tightly with plants.

Somiks avoid open space and do not like bright lighting, as well as increased attention, and hide, so it’s better to feed them in the twilight, in the evening.

When changing water with decreasing temperature, spawning is stimulated. Each female lays 30-40 eggs, which hatch after four days and after three days the fry can be fed with artemia.


Size: up to 6 cm. The content of this type should occur in soft water (up to 10 parts of calcium oxide) at a temperature range from 23 to 25 ° C. Very mobile and active in the afternoon, unpretentious to the quality of water and an armored catfish that get along well with its neighbors. Easily propagated in the general aquarium. Spawning often occurs at night. The female is very productive and lays up to 500 eggs, from which three larvae emerge. After another three days, the fry can be transferred to feeding with artemia. There are various variants of the color of these catfish and it is still not determined whether they can be counted as a catfish golden.


Size: up to 5 cm. They feel most comfortable in soft water with a temperature of 24 to 26 ° C. Somik axelrod is well known and common among aquarists. Care does not cause difficulties, acclimatized catfish spend days in search of food, for which there are no special requirements.

With abundant and regular feeding, females quickly go to spawn. The number of eggs in the clutch is about 40, but there are cases of spawning up to 100 eggs. Small caviar, 1.5 mm in diameter, is attached by the female to the underside of the leaves of the plants. The release of the fry from the egg occurs after four days, and after three days of its formation it is recommended to feed with artemia.


Size: up to 6 cm. The recommended water temperature for the spotted catfish is from 26 to 28 ° C. A type of thermophilic catfish who prefer soft, transparent water with low acidity, and also without nitrates and weekly replacement of up to 30% of the total volume of the aquarium.

With a varied diet very willingly and regularly spawn without lowering the water temperature. Caviar about 2 mm in size, matures for three days, after which the larvae emerge, which feed for three days with the yolk sac, and after two days successfully cope with the planktonic organism - Artemia. The growth of this species is most noticeable in the first two months after it leaves the roe, and when it reaches a size of 2 cm, the growth rate slows down.


Size: up to 6 cm. Soft water with a temperature of 24 to 26 ° C is preferred for keeping this type of catfish. After mastering the permanent range in the content is not too whimsical, so it is suitable even for not very experienced aquarists. In darkened aquariums with a large number of plants acquires a contrasting color, which is inherent even in fry.

Gossi somikov females are very productive and, depending on size, age and condition, can lay between 80 and 300 eggs. Three days after maturation, the larvae emerge from the eggs, which after a two-day adaptation successfully eat Artemia and worms-enkhiterii.

Diagonal strap

Size: up to 6 cm. This type refers to heat-loving corridors. Its content should occur in soft water, the temperature of which is in the range from 26 to 28 ° C. The soil should be sandy, coarse sand or fine-grained stone without sharp edges.

When breeding, transplanting into a separate aquarium is recommended, where the female spreads eggs throughout the bottom. The larvae emerge in two days, and after they absorb the yolk sac (three days), the fry are best fed with artemia.


Size: up to 5 cm. The water content should be between 23 and 25 ° С with calcium content up to 10% (mild).

A distinctive feature of this species is the manifestation of a clear and complete color in a darkened aquarium with plants floating on the surface of the water. Unlike other representatives of corridors with a similar color, napo has black spots on the caudal fin.

These catfish can not be kept with large fish of other species. Mating takes place in free water, in close proximity to the surface of the water. В брачный период бока у самцов отливают лиловым цветом.

Самки откладывают до 300 икринок размером в 1 мм в кустах растений и возле них. Созревание икры проходит четыре дня, по прошествии трех дней после выхода личинок мальки готовы к употреблению в пищу микроскопических червяков и инфузорий. Темп роста у сомика напо очень медленный.


Размер: до 6 см. Для комфортного содержания вода должна быть мягкая, с температурой от 20 до 25°С. Крапчатый сомик ведет активный образ жизни днем и может содержаться с большинством видов миролюбивых рыб.

Cool water is suitable for breeding (fertilization rate decreases sharply in warm water). The female lays up to 250 eggs, from which after four days the larvae emerge, and after two days the fry begin to feed on their own, preferring Artemia in the stern. The rapid growth rate in 2-3 months gives a high similarity with parents.


Size: up to 5 cm. Soft water with a temperature of 22 to 25 ° C provides this kind of well-being and active behavior in the aquarium. Somiki panda need good aeration, filtration and regular water changes, as well as in shelters and a few places darkened by plants. Pandas have shown the possibility of their content with various small tetras and dwarf cichlids.

Reproduction in catfish, all-season pandas. The female lays up to 20 eggs in small-sized plants or Javanese moss. After four days, the larvae appear, which begin to feed on artemia after two more days. This type of corridor representatives is characterized by a very slow growth rate.

For its interesting color and behavior, catfish panda firmly settled with aquarists and received a very widespread.


Size: up to 6 cm. A heat-loving kind of catfish, which prefers clarified water (soft with low acidity) and a temperature regime of water from 26 to 28 ° C. For the successful maintenance of catfish sterns, good aeration is necessary. In terms of species compatibility, they get along perfectly with discussions.

Large females of this species can lay up to 200 eggs, if possible attaching them to a substrate located on the current. After four days of ripening the eggs, the larvae hatch, which on the third day can move freely around the aquarium and eat Artemia.

It should be noted that the fry react very sensitively to an increase in pH, so the purity and constancy of the water composition in the first three weeks will ensure a good survival of the young. At the age of one month, fry become more enduring and less demanding of water, and their further maintenance does not pose serious problems.

Corridors: care and maintenance

The presented types of corridors should be grouped in 5-20 pieces. The size of a specific aquarium for catfish should be at least 54 liters, with the content of the same flock in the general aquarium, the volume should be at least 160 liters, except for panda cats that need a smaller volume of the total aquarium - 112 liters.

Females are distinguished by a larger size and width of the back. And only two species have other, more pronounced differences - the males of the corridor are more miniature than the females and have a clearer pattern, while the males of the speckled catfish are much smaller and sleeker.

The diet for all presented types of corridors is recommended to be made from dry, frozen and live food.

Dwarf, or the smallest catfish

The most popular among the dwarf catfish received:

  • catfish sparrow (eye-tailed catfish, crescent armor);
  • catfish pygmy;
  • catfish habrosus (corridor-baby).

These representatives are the types of carapace corridors found in South America.

It is better to keep the smallest catfish in flocks of 10-30 pieces, the volume of a specific aquarium is 40 liters, and the total - 54 liters, while good aeration and water filtration should be ensured.

When creating the interior of the aquarium, it is necessary to plant plenty of plants, add shelters and snags. As the soil, you can use fine-grained stones without sharp edges, coarse sand.

Somik Pygmy

The maximum size of catfish reaches 3 cm. This type of corridor prefers middle layers of soft water with a temperature of 24 to 26 ° C. With catfish pygmy is allowed to contain many small types of tetras and other types of small fish. In a regular diet, it is better to add medium-sized or finely chopped live or frozen food.

Reproduction in the species aquarium with a large number of plants is most effective. One female lays up to 50 very small eggs that are scattered throughout the aquarium. The gestation period lasts four days, after which the larvae appear, which feed on the yolk sac for the first three days, and then the fry successfully eat the ciliates or larvae of Artemia.

The development of young individuals occurs in the first three weeks at a very fast pace, after which it stops, and then they grow slowly. Fry of catfish pygmy strikingly differ from adult individuals.

Somik habrosus

The size of this species reaches 3 cm. Somik habrosus prefers bottom layers of soft and medium-soft subacid water with a temperature of 20 to 26 ° C and a weekly substitution of up to 30%. The difference between the female and the male is in its larger size and greater width of the back. Habrosuses are peaceful and neighbors many calm fish with the same character and small size will approach them.

Nutrition of catfish Habrosus is from the bottom, prefers fresh or frozen food, allowed to feed dry food and spirulina tablets.

When breeding, the female lays up to 100 eggs in small bushy plants, Javanese moss and next to them. The larvae hatch after three days, the fry after two days begin to move freely around the aquarium and eat Artemia. After six weeks, the young Habrosus begins to acquire adult color. The growth rate in the first two months is fast, and at this age their size reaches 1 cm, and then slows down. Sexual maturity occurs in 10-12 months.

Catfish sparrow

The size of this species does not exceed 3 cm. Soft, clean water with a temperature of 24 to 26 ° C, with good aeration and filtration, is necessary for a comfortable content in the aquarium of catfish of sparrows.

The female is different from the male in large size. By their nature, they are peace-loving and get along perfectly with their own kind in size and size. They are not easily picky and consume live, frozen and dry food, as well as various substitutes.

Before spawning, the difference between the male and the female is obvious: the tummy is more arched and full, the dorsal fin is rounded in the female, and pointed in the male. During spawning, the female lays up to 80 eggs on the glass, the underside of the leaves of plants or another suitable place. The ripening period of the roe lasts four days, after which the larvae appear, which after two days begin to move independently around the aquarium and can successfully eat the aquarium plankton (Artemia, etc.).

During the first month of life, the growth rate of the fry is fast (up to 1 cm in size), and then decreases. By the year of life reach the size of their parents and sexual maturity.

And quite a few videos about speckled catfish and the rules of its content:

Residents for a small aquarium

And so, you read my article on the launch of a nano-aquarium, or you just wanted to start your own little water world for a long time and now you are thinking about who to settle there.

Quite a lot of options)

All the inhabitants of the underwater world can be divided into vertebrates, invertebrates and mollusks.

Vertebrates include various types of fish. To invertebrates - shrimp, crabs and crayfish. To mollusks - snails.

You can choose one of these kingdoms (for example, make a shrimp maker), or you can combine two or even all three.

The traditional is an aquarium populated by fish. Only here you cannot plant everybody in a small aquarium; you will have to choose small schooling fish or one or two medium ones.

Possible options for settling the FISH Aquarium:

1. Petushki:

Very famous and common fish. Males are very beautiful, have luxurious fan fins. Females are less elegant, but also very brightly colored. Breeders are constantly working on breeding new colors of males.

They are satisfied with small amounts of water (but, you see, keeping the fish in an aquarium of less than 5 liters is both cruel and ugly). Water temperature - ideally 26 degrees. The cockerel breathes atmospheric air, swallowing it from the surface. Therefore, care must be taken that the air in the room is not too cool. You can cover the aquarium cover, but leave a few inches from the surface of the water.

Male males are very pugnacious, so it’s best to keep them alone or in families (1 male and 3-4 females).

The body length of an adult cockerel is about 6 cm.

2. Neons

Also known Russian fish. Neons prefer to live in flocks, so it is better to settle them in groups of 5 individuals.

The water temperature is 22-25 degrees (ideally); at higher temperatures, the lifetimes of these fish are reduced. In principle, neons are unpretentious, like soft water and an abundance of plants. Prone to obesity, so they should be fed very moderately.

Adult neon can reach a length of 4 cm.

3. Danio rerio:

As a rule, these small fish are always recommended for beginners. Moving, fun and unpretentious danios feel best in flocks. They can live in the temperature range of 15-30 degrees and be content with 1 liter of water per 1 fish (that is, even in a five-liter aquarium, you can run a group of 5 zebrafish). Easily spawn in an aquarium.

There are several color forms of this fish.

Body length up to 5 cm (but more often 3-4).

4. Guppy:

Probably, it is from this fish that aquarism begins for most people. It was the guppies living in three-liter banks that became frequent inhabitants of Soviet (and then Russian) apartments. They are loved by millions for their unpretentiousness (they can live even in the most extreme conditions), beauty (thanks to the many unique colors, everyone can find "the fish of their dreams" =)) and fertility (you can buy only one female, and in a month she will give birth to you 20 fry).

Viviparous guppies, i.e. they do not spawn, but give birth to live fry. They eat absolutely everything. Water temperatures are undemanding.

At first, I really liked them, but now they multiplied uncontrollably. It even annoys me that every week I find at least 20 newborn fry in the aquarium.

The males are guppies slender, with a bright body and a luxurious tail. Samochki larger, thicker, gray and inconspicuous. But there are quite beautiful purebred females.

Breeders are constantly working on new breeds of guppy.

Dimensions: male - 3-4 cm, female - up to 6 cm.

(last 2 photos - females)

5. Guppy Endler:

In fact, the same guppy. But Endler's guppy is a wild form that breeders did not manage to work on. Such fish are found in Venezuela. easily interbreed with simple guppies and produce very cute hybrids)

Endler's guppies are smaller than ordinary guppies: males reach 2-3 cm in length. Look great in small aquariums with a dark background!

6. Corridor:

The so-called "speckled catfish". In fact, the corridors are very many species, just speckled - the most famous of them.

The corridors love the company, buy at once 3-5 individuals. These harmless catfish do not exceed 5 cm in length, some species (such as the corridor panda) do not grow more than 3 cm at all.

Unpretentious, can live without aeration. The soil should be without sharp stones so that the fish do not hurt their delicate antennae. The optimum temperature of the content - 24-26 degrees.

Water volume: at least 3-5 liters for 1 fish.

7. Corridor Pygmy:

View corridors, which is worth to say separately.

Pygmies are small schooling fishes, seemingly gray and inconspicuous, but very cute and interesting in behavior. They feel good only in a flock, they like clean, oxygenated water.

Unlike other corridors, they do not sit only in the bottom layer of water, but prefer to “flit” all over the aquarium, like a flock of birds.

8. Cardinal:

Prefers neutral water, rather cool (18-21 °). For 1 fish requires 3 liters of water. Small fishes, 3-4 cm, quite mobile. They love the abundance of plants, omnivores.

9. Micro disassembly:

An ideal fish for a nano-aquarium. Body length rarely exceeds 2 cm. Water temperature is 22-28 degrees, unpretentious to the composition of water, 1 fish requires less than 1 liter of water. Unfortunately, micro-assemblies are now rarely available, aquarists have been waiting for these fish to be delivered to stores for months.

10. Norman Blue-Eye:

Cute schooling fish that grow up to 3-4 cm. Their eyes glow brightly with neon light, which gives the aquarium a kind of dynamics and charm.

Peaceful schooling fish, water temperature 20-25 degrees. I live at a higher temperature, very active and playful.

And so, we looked at fish that would be happy even in a small aquarium of 10-30 liters.

Approximate settlement options:

10 liter aquarium:


• 1 cockerel;

• 5-7 guppies;

• 5 neons;

• 5-7 guppies Endler;

• 10-13 microassembly;

• 5 Norman blue-eyed;

• 3-4 cardinal;

• 5-10 Danio-rerio;

• 7 micro-sampling + 5 danio-rerio;

• 3 Endler guppies + 5 danios-rerio;

• 3 neons + 3 guppies.

20-liter aquarium:

• Family of cockerels (1 male and 3 females);

• 1 cock + 3 corridors;

• 10-15 guppies or Endler's guppies;

• 15-20 Danio-rerio;

• 10-13 neons;

• 10-15 Norman blue-eyed;

• 7 cardinals;

• 20-30 microassembly;

• 7 pygmy corridors;

• 5 guppies + 5 neons;

• 15 Danio-rerio + 15 microassembly;

• 10 guppies + 3 corridors;

• 7 neons + 3 corridors.

30-liter aquarium:

Here the possibilities are even greater) For example, such fish may be settled, which I did not tell about here. A pair of macropods, a couple of honey gouras, a pair of pelvicahromis or apistograms.

The remaining combinations - we look at 10 liters and multiply the number of fish by 3.

Naturally, it is better to run less fish than planned. Overpopulation is very dangerous for such small volumes. In any case, filtration, aeration and a weekly water change of 20-30% should be provided.

Nowadays, shrimpers are coming into fashion - aquariums populated with freshwater prawns.

Shrimps are unpretentious, cute and very interesting.

Aquarium SHRIMPS:

1. Cherry shrimp (cherry):

Small (up to 3 cm) red shrimp. Extremely unpretentious. It breeds well in an aquarium.

2. Amano shrimp (Japanese pond):

More than a cherry (up to 6 cm). Gray, perfectly fights with algal fouling. In an aquarium where shrimps live, the plants are always clean and well maintained.

In captivity do not breed.

3. Shrimp Crystal:

Small (2 cm), expensive, rather demanding to water, but very beautiful shrimp.

4. Shrimp Cardinal:

Very beautiful and very rare shrimp. It is considered difficult in leaving.

5. Yellow shrimp:

Unpretentious small shrimp bright yellow. If it is undernourished, it can begin to spoil the plants.

If you want to keep only shrimp (without fish), then you can plant a rather large flock in a small volume. For example, 20-25 shrimp-cherries will feel great in 10 liters.

Shrimps do not touch the fish, but some fish are not averse to eat shrimp. Therefore, the ideal neighbors for shrimp will be small fish, such as the Endler guppies, microassemblies, neons, corridors and Norman blue-eyes.

The calculation is approximately as follows:

20 liters: 10 shrimp-cherries + 5-7 guppies Endler (or other small fish).

Shellfish in an aquarium:

Some snails are also quite cute and even useful. They will be excellent neighbors for your fish or shrimp.

1. Helena:

A cute striped snail that feeds on ... other snails. It helps to get rid of the invasion of pond snails and coils that spoil the plants. For lack of "live food" eats the remnants of fish food. It breeds well in an aquarium.

2. Neretina:

Beautiful and useful snail. Helps to clear a raid from walls and plants. It lays caviar, but the whites do not appear in fresh water.

3. Ampularia:

The most favorite snail, very often found in aquariums.

Unfortunately, some types of ampoulyaries spoil the plants. And there is a lot of dirt from them.


I tried to introduce you to creatures that will feel great in a small (10-30 l) aquarium. Aquarium with small, nimble fish or business-like shrimps will greatly decorate your apartment or office. With proper and timely care, he will long please you.

About how to run an aquarium, I wrote in the article "The underwater world on your desk."

I repeat once again simple rules that will help you to always keep your aquarium in good condition:

1. DO NOT HURRY! The launch of the aquarium should last at least 2 weeks (from the water up to the launch of the fish).

2. Down with artificiality! Plants, soil and decorations in the aquarium should be NATURAL. No plastic!

3. The filter should work around the clock !.

4. Water changes should be done once a week, at 20-30%. Never change all the water at once! Never wash the scenery with chemicals!

5. Feed the fish a little! One day a week - unloading.

6. If after you install the filter, there was a dregs - do not rush to change the water! All is well, the appearance of turbidity suggests that a balance has begun to be established. After a couple of days the water will be clean.

7. Do not overdo it with fish! Less is more.

8. Remember: an aquarium is a complex biological system. Do not climb there once again with your hands, do not make chemistry or other drugs.

9. Fish - also alive. And you are responsible for her life.


There is nothing difficult in aquarism. Learn to be patient, do not neglect the advice, do not forget to devote half an hour a week to your underwater world - and he will thank you. Coming home, you will enjoy the lush green plants and frolicking fish.

Successes to all who decided to start an aquarium!
