Fish for a small aquarium 5 liters

maintenance, care, compatibility

A small aquarium is a tank with parameters of 20×40 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.

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.

See how to make a small 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.

An aquarium with a volume of up to 50 liters is considered small. If you want to avoid the usual mistakes in the selection of fish, use the following tips from experienced professionals.

When buying a fish, ask the sales assistant, what size it will reach when it grows up. Sometimes a small fish in time can turn into a predator, and significantly reduce the number of fish in your tank.

Maintaining the optimum mode in such an aquarium is quite difficult, so you should not buy too expensive exotic fish, such specimens die first of all in case of a violation of the eco-balance.

Calculate the optimal number of fish in the aquarium, based on the calculation – 3-5 liters of water per fish with an average length of 6 centimeters. Do not overload the aquarium with a large number of fish, they will be uncomfortable.

Try to get the fish of one “temperament”. If some fish are inactive, while others begin to rush around the aquarium, the first is unlikely to get food.

Make sure that the vital volume of the aquarium is evenly filled, that is, the fish living in the bottom layer of the aquarium should be combined with the fish swimming in the middle layer and the fish near the surface

The ideal fish in a small aquarium is a guppy. It is possible to purchase about 15 fancy colored fish, and this will be enough for an aquarium of 50 liters.

Small aquariums are well suited for swordtails of various colors. The red color plaits, as well as spotted and calico, have worked well.

Black mollies more demanding on the composition of the water of the fish, it is necessary for them to add a little salt. All of these fish are viviparous, in addition, they require approximately the same conditions. In the small aquarium can be placed and the frivolous fish.

Striped Sumatran barbs look very impressive next to mossy mutant barbs of dark green color. The small striped danio fish are very unpretentious, the cardinal form of the voile look very nice.

Fans of larger fish should purchase several angelfish or pelvihkromisov parrots. Any aquarium will be decorated with red, blue or ordinary neons, but these are rather expensive fish.

It is useful to put catfish antsistrus into the aquarium, which have the ability to clean the walls of the aquarium as well as the plants from green algae using the suction cup.

If you need to populate a small fish tank within thirty liters, then you need to know a few rules.

Rule one. Fish for a small aquarium should not be predatory.

Often acquire fry, not thinking what size they will reach when they grow up. Therefore, you need to ask the seller about the maximum dimensions of an adult.

Rule two. Fish for a small aquarium should not be rare and expensive.

In such containers it is difficult to maintain a stable desired mode. In case of violation of the ecobalance (for example, due to excess feed), they are the first to die.

Rule three. No need to get a lot of fish. A single individual, 5 cm long, requires approximately 4 liters of water.

Easy to count: unpretentious fish for a small aquarium of 30 liters in the amount of 7-8 pieces. will feel quite comfortable.

Rule Four. There is no need to start individuals that are very different in behavioral factors.

For example, some fish are constantly moving, while others are inactive.

Fifth Rule You need to start the fish with a uniform filling of the vital volume. For example, territorial individuals may occupy a larger capacity space, which will cause great inconvenience to other inhabitants.

In addition, the fish must be combined vertically so as not to overcrowd one of the water layers (bottom, middle, top).

The most common is an inexpensive fish for a small guppy aquarium. If you wish, you can find beautiful specimens of intricate coloring.

Swordsmen of different colors feel good in such containers. They are red, black, spotty, green.

In addition, swordtails and guppies can coexist well together.

Another small fish for a small aquarium is black mollies. It is more demanding on the temperature and mineral composition of the water. Therefore, it is slightly salted.

Particularly spectacular disc red pesilia. All these fish are similar in terms of housing, feeding and care.

Fish for a small aquarium: how to choose :: aquarium fish for a small aquarium :: Aquarium fish

Not all residents of modern apartments can afford the maintenance and installation of a large aquarium, so often an aquarium of small volumes is purchased. Choosing residents for such a small artificial reservoir, you must follow a few rules.

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

In a small aquarium should not settle a large number of fish. Acquire fish on the basis of the calculation that one individual requires at least four liters of water. If we consider that usually the volume of a small aquarium does not exceed thirty liters, you should not populate it with more than ten water inhabitants.

In addition, it is necessary to take into account not only the number, but also the size of the fish, because, if quite large individuals grow from fry, they will be cramped and uncomfortable in a small volume of water. Consider also such a factor as the features inherent in one or another breed of fish: some of them are comfortable to live in the lower layer, someone – in the upper one.

Some species of individuals are inactive, others, on the contrary, require continuous movement. Some schooling fish, others prefer loneliness.

When you fish a small aquarium with contradictory qualities, you risk disrupting their life rhythm and creating chaos in the aquarium itself.

A small aquarium is undesirable to populate predatory fish. Fish of tender, rare, expensive and exotic breeds are not suitable for this method of keeping, because in a small pond you will find it difficult to maintain comfortable conditions for them, such fish often get sick and die.
Of the viviparous fish, the most unpretentious are the well-known guppies, they are distinguished by their mobility and very beautiful coloring, their brilliant flock looks very impressive. Guppies breed well, so you need to ensure that the aquarium is not overpopulated with them.
By the guppy it is quite possible to add some bright swordtails, they are also undemanding and will add bright red, black and green colors to your aquarium.
The cockerel fish, famous for its huge “cock” tail and the variety of the most incredible colors, is also very popular.
Black mollies are a bit more whimsical, you have to monitor the temperature and the purity of the water, and this fish prefers salt water.
Of the fish that spawn, for a small aquarium, barbs, small danio rerio and voile cardinals, which require an abundance of algae, are suitable.
Also, not to be superfluous are tiny bright neons whose flocks will always revive the aquarium and please the eye.
All these breeds are distinguished by the small size of the fish and their high viability. If you want to choose a bigger fish, you can buy striped ones, similar to a sailboat, an angelfish, or catfish, which, differing in large sizes and bright colors, get along well with any other fish.

In addition, these beautiful golden, green, and speckled inhabitants of the bottom layer are tank attendants of the aquarium, cleaning the soil and walls from undigested food, dirt and algae deposits.
Thus, if you wish, you can populate even a small, with a volume of ten to thirty liters, aquarium with beautiful fish that will feel quite comfortable, get on well with each other and decorate your home.

Many cockerels are sold in pet stores, where they are settled in small glass jars. Is it right to keep a fish in such conditions?

Of course, this is undesirable. Despite the endurance of the fish, the aquariums for the males should be spacious enough for free movement. These fish will show their color as brightly as possible, they will stretch their fins if they live in a comfortable environment.

It is important that your cockerel fish could easily turn around in the tank, without restricting themselves in their movements. Moreover, in the close capacity it is impossible to place the plants, decorations, filter.

Improper settlement leads to diseases of the pet, and other negative consequences. Sometimes in the banks where the roosters were kept there could be drugs (methylene blue), there was no heating at all. In general, the fish simply will not survive if they limit the space.

And where can they settle?

Of course, aquarium fish can not live in a glass of water or a 1.5-liter jar. The size of the cockerels is 5-6 cm on average, so they need at least a little open space, but with space for free movement.

If you can’t get an aquarium, you can put your pet in a 3-5-liter jar of infused water for a while. In it, oddly enough, you can put some decorations or plants. However, the cockerel is not a Spartan, so the best conditions for him are special aquariums for cockerels.

Through the decorative tank it will be pleasant to watch the fish, there it will be able to quickly get used to it, and even produce offspring.

Look at what aquariums are for keeping cockerels.

An aquarium of 20 liters of a rectangular shape is probably simple in appearance, but is better suited for a fish than a glass jar. The fighting fish can calmly turn around in it, enjoy the scenery, in such a tank it is possible to maintain stable water parameters.

It will not overheat much, maintaining a stable biobalance. In a 20-liter aquarium, it is easy to create an aquascape with decorations, plants, snags and stones.

It can even run not one, but two fish.

10-liter rectangular shape – if you do not have the opportunity to buy an aquarium of 20 liters, take a smaller tank. This is the minimum allowable amount for keeping one adult cock.

However, it is much more difficult to maintain the equilibrium of the aquatic environment, it will quickly become dirty and warm.

A circular cockpit aquarium – there is a perception that in cockpits many cockerels have finished their best years, but this is not quite so. In round tanks it is not bad to keep a pet in quarantine until she gets used to the new environment.

Round containers serve as a good carrying for the fish, they can be installed small decorations, and even a filter. It is more difficult to clean this design – the usual scraper can not cope with algae settled on the glass. The brush will not help.

It is believed that such forms of tanks badly affect the eyes of the males, they distort its appearance from an optical point of view. Of course, you can choose such an aquarium, but rectangular shapes are much better and more practical.

They are easier to maintain.

Look at the original idea of ​​the content of cockerels.

For the 5-centimeter fish fit well decorated tank. You want the fish to have a full life?

Then take into account the fact that the optimal aquarium for a rooster is made in production. Many companies offer aquariums for betta fish of a round, rectangular, even square shape. They immediately installed a lamp, lamp, decor, filter.

Another thing – cockerels do not need constant lighting, so the lamp does not need to keep it on all the time. Light like algae, and why do you need extra trouble with cleaning?

Try to buy a simple 20-50-liter rectangular tank with filter and lamp. Scenery, soil, shelters can be installed independently, if you know how to handle them properly.

Before settling the fish, wash the glass in a tank under running water and process with baking soda, rinsing it 4 times. From this it follows that the best house for the cockerel fish is a classic rectangular one, where there is everything to recreate the natural biotope.

Although the males of these small fish of the family Melanoteni can fight with each other, but in fact they are peaceful fish. Often are the victims of other fish that love to pluck their long fins, so it is better to settle to the same peace-loving species.

When kept in a good and spacious aquarium with a volume of 50-60 liters in a group of at least 6 individuals, they will demonstrate interesting behavior and good character in relation to the same neighbors.

See what Werner’s iriaterina looks like.

Carnegiella marble is an excellent choice for an aquarium of 60-100 liters. Swim in the upper layer of the aquarium.

They have a very interesting appearance: their wedge-shaped abdomen and variegated color immediately attracts the eye. They are calm and shy, can leave other fish alone. Aquarium fish are kept in groups, it is recommended to settle a flock of 6 individuals at a minimum.

A flock prefers to swim in the upper layers of the water, without disturbing the bottom fish with a peaceful disposition. However, the aquarium should have a cover so that the fish do not jump out of it.

Sometimes you can hear blows on the cover – it means that it frolics or requires attention to itself.

Fish twig, or catfish farlovella (Farlowella vittata)

Catfish Farlovella is an excellent choice for lovers who want to take care of the cleanliness of the home aquarium. These herbivorous catfish definitely will not hunt fry of other fish, and even small-sized fish. Prefer calm, peaceful aquariums, where there is no place for hostility.

Do not take food from others, and eat up its remnants.

They grow up to 15 cm in size, so they should be placed in spacious aquariums of at least 120 liters. Sensitive to the parameters of the aquatic environment. Fish twigs – the best algae eaters.

For their content requires constant feeding of plant food – zucchini and algae plates, otherwise aquatic plants will eat. Compatible with peace-loving fish swimming in the upper layers of water.

Panda corridor – small fishes of the Pantherfish catfish family. They can live in an aquarium of 50-100 liters.

These are bottom fish that prefer rectangular aquariums with a sandy substrate. Like other aquarium catfish, you must live in a group of 5-7 fish to feel safe.

They are contactless, friendly, sometimes they play games and catch up without hurting each other. Sometimes demonstrate hyperactive behavior.

The best neighbors for them are other corridors of small size, and small fish up to 5 cm in size, which do not show an aggressive disposition and swim in the upper and middle layers of water. It is important that catfish get food that they collect from the bottom.

How to equip and whom to settle in a tank of 40 liters

Sometimes there is a situation when going to visit friends, or just going into the room, the first thing that catches your eye is a magnificent aquarium and beautiful fish swimming in it. It is not surprising that practically everyone has a desire to create such a work of art at home.

But what if the money is only enough for an aquarium with a capacity of 40 liters? Is it a lot or a little?

And what fish to inhabit it? And this is not to mention the subtleties associated with its arrangement.

We will dwell on these nuances in more detail.

Does fish growth depend on the size of an artificial reservoir?

There is a theory that claims that the size of a fish directly depends on the size of the vessel. And to be frank, there is a grain of truth in it. If you take, for example, roomy aquariums, then the fish that inhabit it grow up much faster and grow in size.

If you put the same fish in a small aquarium, the process of its growth will not stop, but the rate of maturation will decrease significantly. But It is worth noting that, even being in a small container, but with proper care, you can get incredibly colorful and fascinating appearance of the inhabitants of the underwater world.

But do not forget that if large aquariums do not require frequent maintenance, then a smaller vessel is needed more often. Therefore, it should be several times a week not only to add water, but also to regularly clean it.
