maintenance, care, compatibility
Small consider aquariums less than 30-40 liters, usually from 5 to 20 liters. Often they are called nano aquariums (from the Greek nano – “small, tiny, dwarf”), emphasizing with this term not only size, but also their modernity and adaptability. There are also microaquariums, their capacity is 1-2 liters, and animals do not lodge in them, with the exception of some species of snails. The world’s smallest aquarium with fish was created by Omsk miniaturist Anatoly Konenko and his son Stanislav.
They placed in 10 ml of water a primer, a specially designed mini-compressor, small cladofor bushes and a few danio fry.
We will immediately agree that we will not call a round ten-liter jar with a goldfish a nano-aquarium because it is not an aquarium, but a mockery of fish and all the principles of aquarism.
An aquarium, no matter how large, is an equilibrium biological system whose inhabitants feel comfortable. To achieve this in a small amount is a whole science.
But, if this is possible, the results can be simply amazing. Such aquariums, where a living biotope is reproduced in a tiny volume, resemble Japanese bonsai art or large-scale models of luxury cars: small ones, but everything is real.
Of course, not all small aquariums are worthy of aquascaping competitions or books of records, but each of them should please the eye of its owner and create a comfortable environment for its inhabitants.
Nano aquariums are rectangular, cubic or close to it. Cover usually with a transparent coverslip. glass that allows you to admire them from above.
Keep them away from drafts and direct sunlight and closer to the outlet that you need to connect equipment.
Equipment for nano aquariums is generally the same as for large ones, that is, a filter (in some cases it is enough to have a pump with an aerator), lighting devices, a heater if necessary, better complete with a thermostat, and a carbon dioxide supply system.
For those who do not have the experience and time to select aquarium technology, fully equipped nano aquariums are on sale. The best in terms of price and quality are the complexes of the Aqua El Shrim Set and Dennerle Nano Cube series.
And if you want to save money or it is interesting to choose all the stuffing for your nanocube yourself, there is plenty to choose from.
Choose plants in the nano aquarium should be depending on the power of lighting and whether the supply of carbon dioxide is organized. If the light is bright, the soil is specialized, containing organic matter and CO2, then you can plant any medium-sized plants, here only the preferences of the owner play a role.
In a more modestly equipped aquarium, plants are limited to unpretentious and slow-growing plants.
Lileopsis is a Brazilian cube, hemianthus of cube, and marcilia are used as ground cover. Japanese Blix, which is considered a groundcover in large aquariums, looks like a bush in small volumes.
In addition, different types of Anubias, cryptocoryne, Pogostemons, Rotal, ferns are grown. For decorating snags, stones and items of equipment use mosses. Often you can meet the cladofor balls.
In short, there is room for creativity almost like in a large aquarium.
When choosing inhabitants for a small aquarium, first of all, of course, one should pay attention to their size. Fish should not be more than 3-4 cm long, and if the aquarium is completely “nano”, up to 15 liters – more than 2-3 cm.
In addition, the fish need a peaceful, not too voracious, not territorial, and quite unpretentious, at least if this is your first experience in nano aquariums. Well and, of course, they must be brightly and diversely colored and active, so that it would be interesting to watch them.
Under these conditions is quite a large number of fish. The most honorable place in nano aquariums is occupied by carp representatives – zebrafish, micro-assemblies, boraras.
The micro-collection of the galaxy with its amazing color is truly the queen of small volumes.
It is possible to lodge neon and tetra amanda from charicine fishes in such an aquarium, from guppies and petillia from viviparous. In addition, you can make small catfish, for example, the corridor-pygmy or otozinclus.
Feel good in a small volume of the cockerel.
Fish is better to take flocks of 3-4 pieces (of course, except for pugnacious cockerels), so they will feel more comfortable. The density of planting small fish should be about 1 individual per 2 liters of water.
In addition to fish, different types of shrimp live in a nano aquarium, dwarf crayfish (they are incompatible with shrimps), frogs hymeno-viruses.
You can decorate a nano aquarium in a different style. Iwagumi styles are popular among aqua-designers – different types of stone decoration forms, ryubekuka – decoration with snags, wabikusa – in the form of a hummock with plants.
But here the taste and preferences of the owner are crucial. For example, if an aquarium is in a child’s room, it is appropriate to place a mermaid’s castle or a sunken ship and toy scuba divers into it.
The main thing is that the scenery should not take up too much space (as a general rule, not more than a quarter of the bottom surface and half the height), hide the aquarium equipment and leave room for plants and fish. In addition, if there are shrimps in the aquarium, it must be borne in mind that any objects protruding from the water may contribute to their escape from the aquarium.
Soil in small aquariums usually use a two-layer one: the bottom layer is a nutrient substrate, the top one is gravel, the total thickness of the layer should be 3-4 cm.
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.
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.
The most unpretentious and small aquarium fish with photos
I think many aquarium fish experts will agree that the first place is given to guppes.
Everyone probably knows these fish … even those who have never seen aquariums. We can say that these fish are the fish of all children of the former USSR (they were in all Soviet aquariums))).
The fish is very beautiful and unpretentious. The tail fin is her beauty. The simplicity of the fish is that it can withstand “difficult conditions of detention.”
I happened to see an aquarium with guppies. without aeration, without filtering, without plants, without proper feeding etc. – horror, terrible dream aquarist. Nevertheless, guppies managed not only to survive in such an aquarium, but even tried to multiply.
So to mock the fish of course not worth it. But their endurance and vitality sometimes affects.

2nd place Swordtails
A very famous fish, as a result of persistent selection, a large number of swordtails of various colors and shapes were bred. Males differ from females by the presence of a “sword” on the lower edge of the caudal fin.
Swordtails are kept in flocks in a densely planted aquarium. The minimum size of the aquarium from 10 liters (but better is more).
A good volume of aquarium for a small group of swordtails is 50 liters.
An interesting fact about these fish is that the female swordtail can, at some point, become a male, i.e. change the floor. This is due to the struggle for the survival of the species.
HOW AND GUPPI ARE RECOMMENDED, ALL THOSE WHO DO NOT WANT TO DEAD WITH THE AQUARIUM.

3rd place Somiki corridors
It should begin with the fact that all aquarium catfish – a priori unpretentious. Moreover, they are “orderlies of the aquarium world”: they clean the soil and eat the remnants of life activity.
The corridors are chosen from all catfish, since in addition to the gill, they have intestinal respiration, those. if aeration stops, they will live for a long time.
The fish are very peaceful, calm. They slowly swim along the bottom in search of food. In the aquarium they are usually kept in flocks.
Fish, do not pose any threat to other inhabitants of the aquarium.

4th place Mollies
Molly, like guppies – viviparous fishes. Unpretentious and tolerant of poor conditions.
Nevertheless, they are more capricious than the “troika of winners”.
Fish suitable for beginners and young aquarists. The fishes most difficult to keep from all members of the family are demanding of their conditions, they do not tolerate low temperatures, some like “salty” water, like bright light, etc.

5th place Tetras – Harazinki
All tetras are small, brisk, not capricious fishes. However, they will not be able to survive in “Spartan conditions” as guppies.
They need aeration and filtration. You can keep them in an aquarium by a group (from 5 individuals) with a volume of at least 35 liters of water.

Some individuals taken separately are even very aggressive, as they say, as lucky.You can read more about GURAMs here.
10 place Barbus
Barbusses are schooling, small fish that can stand up for themselves! If you decide to start a barbus, I recommend to allocate for this a separate aquarium, “barbusyatnik.” “Pirate” temper, the ability to stand up for themselves – deserve 10th place.

Not every person can afford to buy and place a large aquarium at home. Sometimes there is simply not enough free space, and one wants to decorate the interior of the dwelling and have this kind of pets at home.
Often there are cases when small aquariums are purchased in order to put them in their workplace, thus decorating the office. But it is important to remember that a small aquarium is very difficult to maintain. The difficulty is to properly maintain a sustainable biological system.
Not every novice aquarist will be able to choose the right fish for a small aquarium.
Characteristics of a small aquarium
Experts advise not to buy very small vessels. The fact is that in small aquariums it is simply impossible to maintain the parameters that are necessary for the life of the fish.
For example, for keeping fish in a small aquarium, you need to maintain a stable temperature regime. There are fish that need the temperature in the aquarium to reach 18-20 degrees, and there are tropical species that require temperatures above 25-27 degrees.
At home, it is very difficult to maintain a stable high temperature of the water in the aquarium. At the same time, the water temperature remains one of the most important parameters for keeping fish.
In addition, as long as the bacteria do not settle the filter, the aquarist will have to frequently change the water. For replacement water is suitable, which
defended for at least two days.
Selection of equipment and plants for a small aquarium
Aquariums with a small volume are sold in specialized stores. The kit usually sells a cap, an air pump, a filter, and a light. That’s all it takes.
Usually such kits are not expensive.
The choice of plants in a small aquarium directly depends on the size of the aquarium. Large and fast-growing plants in the design of small aquariums should be avoided.
They will occupy the entire volume and will cause a lot of trouble.
For small aquariums, small species of Anubias and microzoriums are ideal. The advantage of these plants is that they do not need to be buried in the ground, but only easily attached with wire to the pebbles at the bottom. Successfully will look and cryptocorynes.
You can use different mosses for decoration. Especially advantageous they will look in an aquarium with shrimp.
Selection of aquarium fish for a small aquarium
From viviparous fish for a small aquarium, you can choose guppies. This is a common and inexpensive fish.
You can purchase red, spotted, black or green swordtails. As an option – to get placium or mollies.
These relatively unpretentious fish for a small aquarium, there are different colors.
You can choose barbs or danios or have catfish ancytrus from the fledgling fish.
Often for the design of the workplace choose round aquariums. When choosing fish for a round aquarium usually stop at certain species. Often you can see a goldfish in a small aquarium.
Sometimes in mini-aquariums they keep frogs, tritons, shrimps.
A betta fighting fish in a small aquarium will also feel great, as it can breathe atmospheric air. This feature explains the choice of this type of fish for small round aquariums.
It can be concluded that when choosing fish for a small aquarium, many factors must be taken into account, but mini-aquariums are worth the effort, as they will be a great addition to the interior.
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.
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.
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.
