How to choose fish for a small aquarium

Aquarists know that even the smallest aquarium can be turned into a work of art, if you populate it with the "right" fish and create comfortable conditions for them. There may be many criteria for choosing pets, for example, color and personal tastes, but it must be remembered, it is important to consider their compatibility and the rules of settlement.

The size of the aquarium dictates its conditions

Small recognized aquarium less than 50 liters. So, even in a 10 liter miniature pond you can settle the fish. However, it is worth calculating your efforts, the smaller the liters, the more often you need to do the cleaning, monitor the quality of water and aeration. If you plan to keep tropical rocks in a small aquarium, then you will have to maintain an optimal temperature for their maintenance, about 26-27 degrees. In Akavirumah with a volume of less than 10 liters, this is very difficult to do, since the instruments have large scales that will not fit physically there. Ignore these conditions, too, will not work. Without them, the fish for which you gave more than $ 100 will die.

We carefully study the compatibility of species.

Fish for a small aquarium should be selected depending on many factors. For beginners, it is problematic to consider them yourself, so contact the professionals who will help determine which fish can be kept together, and which neighborhoods should be avoided.

Factors important at settling:

  • The ability to survive one by one. Some species can live only in flocks, so pay attention to this moment in the first place;
  • Water characteristics for species should be approximately the same;
  • Peaceful nature of the inhabitants;
  • The number of individuals depends on the surface area of ​​the water. The larger the footage, the more fish you can start;
  • Compatibility of rocks. Sometimes peace-loving fish separately do not tolerate each other's neighborhood.

It is important to remember that small aquariums - a zone of increased danger to fish. Therefore, the choice of neighbors fully determine the fate of your wards. If you add predatory fish to a small aquarium, they will eat peace-loving neighbors. For the angelfish fit gurus, other fish with them will not get along. You can get one fish, which will be the mistress of your reservoir, or keep a whole flock of miniature fish.

Unbreakable canons of settlement

Depending on the volume, you can have a different number of individuals. Thus, in the 10 liter can be placed 2-3 fish to 6 centimeters. If you do not follow the rule of displacement for each representative, then you will create an uncomfortable atmosphere, which will worsen the health and appearance of the inhabitants. In addition to the fish in the aquarium will be gravel and plants, which also take up some volume from the declared manufacturer.

Another nuance in the settlement of fish in the smallest aquarium. Consider the habitat of pets so that they do not interfere with each other.

Fish are divided into those who:

  • Swim near the bottom - bottom;
  • Swim at an average level;
  • Swim in the upper layer.

With such a gradation, the inhabitants will be evenly distributed in the aquarium, which will significantly increase its aesthetic properties. Let us turn to specific examples of ideal inhabitants.

Cockerels

Cockerel perfect fish for a small aquarium. Based on the name, you can easily imagine how they look and their character. Small teasers with a stunning multi-colored color will become an ornament. You can find monochromatic representatives, often come across multicolored - red with iridescent in different shades and colors look truly great. The optimal volume for one individual - 7 - 10 liters. There is a trick in keeping one cock in the aquarium. Place a mirror in the water that creates the illusion of an opponent who will invigorate your pet. It is desirable to have no more than 1 male per 3-4 females per one aquarium. If you decide to launch another "man", then you need to take care of the partition, which will protect them from death as a result of a skirmish. The ideal neighbors are barbs and danios.

Guppy

Often, it is from them begins acquaintance with the world of aquarium. They are able to survive in any environment. Omnivorous pets have a great color, which you can talk for a long time. Different types of guppies have a different structure and color of the fins, which will make the artificial reservoir incredibly beautiful. Over time, fashion does not pass on them, so whatever residents you may have brought, you will always remain at the height of fashion. Minimal maintenance of comfort in a 10-liter aquarium is enough to produce offspring.

Somics

Buying catfish is a very reasonable way to minimize their own efforts in maintaining the aquarium. Since they feed mainly from the soil and stones, they perform the role of cleaners. In addition, they are completely safe neighbors. If you decide to settle soms, then give preference to 5 identical individuals. 2 representatives need at least 10 liters of water, so counting the number of running soms will come from the number of available centimeters.

Aquarium fish for a small aquarium

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.

Tips for picking fish

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

Fish in a small aquarium

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.

Combinations of fish

A good combination is the acquisition of 5 ball carriers, 3 catfish antsistrusov, 5 petily, and 10 neons. 5 Danios, 10 guppies, 3 swordsmen, and a pair of speckled catfish will get along well. Another optimal combination is the presence of 4 mossy barbs, 2 angelfish and 3 catfish antsistrusov. This list can be continued, the main thing is to follow the above tips.

Everyone decides what kind of fish to acquire, as long as they combine with each other.


How to care for a small aquarium?

Small can be considered an aquarium from 20 to 40 cm in length (I note that there are still nano-aquariums, but this is more of an art). In smaller than these, it is difficult to keep practically any fish, except perhaps the rooster or cardinals. Small aquariums need practically the same equipment as for large ones. Especially important is the heater and filter. A good lamp does not hurt if you want to keep plants or enjoy your fish to the fullest.

Stability in a mini aquarium

Compared to the environment, the mini aquarium is very small, but choosing the right fish and plants will not be a problem. The main thing that the fish had enough space for her normal life. Some fish, such as the cockerel, even prefer small aquariums, this is due to the fact that many small fish live in nature in ditches, often even in large puddles.

The biggest problem in mini-aquariums is the small amount of water. And as a result, any changes in it are instant. In a larger aquarium, changes in the composition of the water as a result of contamination are not as significant as if the same amount enters the mini-aquarium. For comparison, one gram per 100 liters of water will give a concentration of 1 milligram per liter, and the same gram per 10 liters will yield 10 milligrams per liter. This means that any shift in balance - overfeeding, the death of fish, a rare replacement of water, instantly affects the state of the mini-aquarium.

The only way to avoid all this in a small aquarium, regular monitoring of water parameters, maintenance, and most importantly, moderate and adequate feeding.

Care for a small aquarium

Caring for a mini-aquarium is very simple and is based on the same principles as caring for a large one. Replacing a portion of the water is a key point, a little and often, here’s the golden rule. Very often aquarists clean the tank every month and replace all the water. But only in one case, you need to change in the aquarium more than 50% of the water - if an emergency happens. In nano-aquariums, a large water change still introduces instability and imbalance. A good habit is to change no more than 10-15% of the water for a mini-aquarium at a time. If you need to replace more, break for several times. Three times 10% better than one 30%.

Filter care

In mini-aquariums there is the simplest internal filter - a pump with a sponge inside. Never wash this washcloth in running water! Thus, you kill the beneficial bacteria that are involved in the nitrogen cycle. Just choose a finely porous! Identical at first glance, they have different pore sizes, and fine dirt can fly through large pores and return back to the aquarium. This will significantly reduce the chance of instability in a mini-aquarium.

Plants in a mini aquarium

Living plants are needed in small aquariums, as they help remove hazardous substances from the water - nitrites, nitrates and ammonia. Plants in a mini-aquarium create additional insurance and reduce stress in fish. They are also very convenient for growing some small species of plants, because in a mini-aquarium it is easier to create good lighting, and in large light simply does not reach the bottom level in necessary quantities.

To choose the right plants for your aquarium - read the materials on the Internet and talk with experienced vendors, they will always help.

Feeding

The most important point. The food you give is the main source, and in some cases even the only one, of various decay products. The less you feed, the less dirt and the more stable the aquarium. Of course, the fish must be well fed, and your task is to keep the balance between the well-fed fish and the overfed fish.

A good way is to give as much food as fish eat in a minute so that no food will fall to the bottom. Factory feed for fish, in the form of flakes, a good choice for a small aquarium, it slowly sinks and gives less waste, but also gives small waste and feeds they need not excessively. It is better to feed the fish in the new aquarium for them. When the balance is established, or you start the bottom fish, for example, catfish, you can add other types of feed for a full diet.

What kind of fish can be kept in a small aquarium

Choose a fish for a mini-aquarium is quite a challenge. It is not enough for this simply to choose a small fish, although this is the same factor. It is also important not to forget that the fish you choose will live in a limited place, which means you cannot stop at the types of aggressive or territorial. A common mistake is to buy male swordtails, dwarf gourami or cichlids, they can be real hooligans. And the types of active fish, such as danios, get along well, but can interfere with other fish because of their vigor.
A good choice for a mini aquarium is small barbs, for example, cherry and many types of haracin ones - neons, rasbora, erythrozonuses. To clean the aquarium, corridors of all kinds are well suited, or algae eater - ototsinklyus. From shrimp - Amano shrimp and cherry shrimp.
There are still not very famous fish, but which are ideal for small aquariums:

  • Pseudomogil gertrude
  • Copper tetra or Hasemania nana
  • Orizias vovora (Oryzias woworae) or rice fish
  • Tetra Amanda

Neon

For the upper layer (although they float everywhere), partilias and mollies. Guppies are also very popular, but I would not advise taking pedigreeds, because of their very weak resistance to diseases, the result of intragenital crossing, you can take an endler's guppy. The endlers are 2 times smaller than normal guppies, much brighter, but the fins are not voile. Breed more often, the fry are larger, but less at a time than the usual guppies.

The male cockerel can become a highlight, but only it is better to keep him alone, because of the violent temper in relation to relatives.

Fish for a small aquarium: how to choose

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

Some important 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 tanks, 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).

Types of fish for a small aquarium

Viviparous

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 spawning

Striped Sumatran barbus looks very good, especially mossy barb - a mutant of green color.

Danio fish are small and completely unpretentious. Cute voile cardinals are also small in size and are suitable for such containers.

The smallest fish for the aquarium, perhaps, are the neons of the Haracin family, but they are somewhat more expensive. But neon (red, blue or ordinary) is considered the most spectacular fish among all freshwater schooling representatives. A flock of 10-15 individuals will become a real decoration of any aquarium.

If you want to buy larger fish, you can stay on a pair of scalar or parrot pelvicahromis.

Small catfish (gold, mottled, green) get along well with any fish. They live in the bottom layer, feed on the remnants of food at the bottom, thereby cleaning the ground. And catfish antsistrusy, due to the structure of the mouth-sucker, clean the walls of the aquarium from algal deposits.

The number and composition of the inhabitants of the aquarium entirely depend on the preferences and availability of finances of its owner.

Unpretentious aquarium fish - the owner does not bother

Is it difficult to keep aquarium fish? Such a question is often asked by novice aquarist lovers. They are afraid that they will not cope with the care, feeding, settlement of pets.Like any living creature, aquarium fish requires attention and care, but how to create comfortable living conditions for it, if you don’t know enough about the aquarium business? In this case, your pets can become unpretentious aquarium fish. They are easy to maintain, unpretentious fish are considered very hardy, tenacious, get used to the person. If you are very busy, and you do not have enough free time to care for animals, then the most unpretentious aquarium fish will significantly reduce the time for employment of the aquarium.

List of small unpretentious fish

What unpretentious aquarium fish successful for a beginner who does not have much experience in maintaining the aquarium? When there is a desire to create good conditions for their pets, you can choose small and beautiful fish with a peaceful disposition, who can live in not very capacious tanks.

Guppies are one of the most popular decorative pets in an aquarium. Outwardly very bright, cute, have a beautiful tail. You can keep in small tanks of 40 liters, are able to transfer changes in water parameters. Some guppies can withstand the lack of filtration, aeration, plants, although such a settlement is not strongly recommended. Guppies are prolific, viviparous fishes. Perfectly get on with small and peaceful fishes. For this reason, they have been popular in our country for many years. In addition, the variety of color patterns is striking - you can choose a school of fish of different colors, whose offspring will be even more colorful.

Watch a video about the content, care and reproduction of guppies.

Swordtails - they are easily recognizable by the tail fin, which in males ends with a "sword" in the lower base of the tail. There are also many types of swordtails: color variations, sizes, behaviors prove that these are very interesting pets. The main advantage - they are hardy, livable with many ornamental fish, do not spoil the aquarium decorations. It is advisable to settle in a 20-50 liter tank, where there are many shelters and dense vegetation. Swordtails can stand up for themselves - they can be accommodated with active fish that love to disturb their neighbors. Swordsmen are survivable because the female of this species suddenly becomes a male, which saves her in a critical situation.

Somiki corridors - unpretentious inhabitants of home aquariums. As you know, catfish are generally undemanding in maintenance, they are even ready to help in cleaning the tank - they eat up the remnants of undernourished food, eat algae. Do not bother their neighbors, because they float in the lower layers of water. Corridors can be called "two-breathing" fish, except for gill breathing, gather air into the intestine, which helps them survive in the absence of aeration. The nature of the fish is calm, peaceful, they can be settled even with larger fish. It is better to have a flock. The minus of these pets - some individuals carry with them parasites, if kept before the purchase is wrong. Their sizes are small - from 3 to 10 cm, so you can settle in small aquariums.

Mollies are viviparous fishes of the Pecilia family. Rather hardy, maintain small changes of parameters of water. However, their bodies do not withstand bad biological stress - dirty water, low water temperature, fresh water. Prefer salted ponds and bright lighting. Some mollies may conflict with the swordtails, barbs. The character is peaceful but unpredictable.

Tetras are another popular fish of the Kharacin family. Unlike corridors and guppies, they will not be able to survive under stringent conditions of maintenance - they need a lot of dissolved oxygen in pure water. Schooling fish, you can settle in a common tank with a capacity of 35 liters, a flock of 5-6 individuals.

Gourami - easy-to-keep fish, suitable for beginners. Need a portion of atmospheric oxygen, so you have to follow the aeration. Gourami are able to stand up for themselves, they eat live, frozen and vegetable food. Sometimes gourami can show aggression towards the fish of their own species.

See how to contain pearl gourami.

Barbus - easy to care for and keep pets, but with what character! Considering the fact that they are schooling fish, they can reach other neighbors, especially bright ones with lush fins. These are pirates of domestic aquariums, they can disturb even large cichlids, they are not suitable for a small common aquarium. Advantages of barbs - endurance, livable, beautiful appearance.

Unpretentious large fish

The most famous aquarium fish, which have relatively large body sizes, are representatives of the Cichlid family. Not only that they are very beautiful, so also peaceful, interesting, clever. Cichlids quickly get used to the person, can be fed from the hand. From a young age they form a couple, skillfully care for their offspring. Representatives of this family that are common in domestic aquariums are freshwater astronotus, angelfish, discus, African and South American cichlids. The size of cichlids is from 15 to 30 cm; therefore, they require settling into a spacious tank with a capacity of 100 liters or more. They get along well with some peaceful fish, however, they differ in territorial behavior. Tolerant changes in water parameters, but not drastic. There is one "but": some species of cichlids should not be given as a pipe stacker and bloodworm, it is harmful to them. This point should be taken into account when settling in a common reservoir.

❶ How to choose fish for the aquarium :: large aquarium fish :: Aquarium fish

Tip 1: How to choose fish for the aquarium

When choosing aquarium fish first of all it is necessary to find out how the different species are combined. Did you know, for example, that guppies and barb are not neighbors? An aggressive and agile barb will simply drive the sluggish guppies into a corner and wrap their beautiful tails!

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

Instruction

1. Before going to the pet store, you need to decide on the volume aquarium. In a small aquarium fit small fish, for example, schooling: neons, guppies, barbs. But a golden fish or a large representative of the cichlid family will have a hard time living in a “can” of 20 l. It is best to adhere to the following formula: for one fish less than 3 cm in size, 1 liter of water is needed, from 3 to 5 cm - about 3 liters, and for a fish about 12 cm - at least 10 liters.

2. Before buying fish equip an aquarium with shelters and plants. Macrognathuses, apteronotuses, many catfish species love secluded places. And cichlids, scalars, molines, guppies, neons, zebrafish and goldfish, on the contrary, adore a large space for movement.

3. Aeration and cleaning equipment must be selected in advance. The better and better it is, the more fish you can start. For example, not 5, but 7, but not more.

4. Aquarium fish can be divided by the type of temperature comfortable for them. Guppies, neons, molines, gourami, barbs, etc. prefer warm water - 27-30 degrees. And for cold-loving fish - crucians, gold fish, burbot, danios and tetras the temperature will suit 23-25 ​​degrees.

5. Keep a balance between slow and moving fish. Some slow fish, such as gold, telescopes, gourami will not get along with fighting cockerels or barbs. At the same time, a brisk flock of neons can be "not out of evil" swallowed up by large goldfish. Catfish sticking can be eaten by barbs, if you do not feed them or do enough shelters for catfish. There is a lot of tricks in aquarism, it’s not for nothing that many people single it out into a separate science.

6. Do not forget about what you want to see in your tank. If you come after a hard day’s work and, looking at the “underwater world”, you want to relax, it’s better to take calm fishwhich, like a pendulum swinging from side to side, calm your nerves and bring harmony to the soul. If you need "fights without rules", the cocks or barbs will suit you, which sometimes arrange "something"!

7. Separately, it should be said about some types of cichlids that have special intelligence. At first, they have a very interesting love relationship, then they build houses together, and a little later they care for the younger generation. What is not the Mexican TV series?

Tip 2: Fish for a small aquarium: how to choose

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.

Content policy

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: it is convenient for some of them to live in the lower layer, for someone - in the upper layer. 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.

Which fish to choose

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, known 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 most beautiful fish for the aquarium

What kind of fish to have a novice aquarist?

In order for the fish to please their owners and to reveal the amazing underwater world to the aquarist, they need to provide comfortable conditions of detention. At the same time, they should feel safe and not be constrained in their movements.

Preliminary preparation before the acquisition of small fish

If you have never had an aquarium and no experience of keeping fish, then it is best to start fish that need minimal care and are not very demanding to the conditions of existence. This will avoid the death of your fish, as well as gain experience and knowledge in the content of the aquarium.

Many tropical fish require the maintenance of a certain water quality (hardness, acidity, temperature, etc.), the presence or absence of plants, a certain brightness of the light or its absence.

For unpretentious fish, the range of comfortable conditions is much wider, which allows them to be kept in a lower-quality environment. They are also less susceptible to negative factors (improper feeding, delayed water changes, etc.).

There are several determining factors when choosing a fish:

  • aquarium size;
  • selection and compatibility of different types of fish;
  • the size and temperament of the fish.

If you already have an aquarium, you need to determine what and how many fish you can fit into it. This will avoid overpopulation, which leads to unnecessary fights, oxygen starvation, eating predators of peace-loving fish.

Aquarium size

If you have enough space and money to install an aquarium of any acceptable size, as well as the necessary equipment to ensure the life of the fish, you can proceed to the next heading of this article.

If you are cramped in something, then you need to define your desires, given that small aquariums are much more difficult to maintain than large ones, but the latter require more time for maintenance. For example, a 100-liter aquarium will suit a novice aquarist better than a 50-liter aquarium.

A large aquarium is simpler and better kept for several reasons:

1. Water temperature and quality are more stable.

2. The impact of adverse factors on the fish takes longer, which gives the novice aquarist the opportunity to influence them in a timely manner. For example, in winter time, the water heater broke, the cooling process is slower and you can manage to get off and buy a new one before the fish get cold. Or ampularia died from old age in the thickets of a small aquarium, the water became dull, the smell appeared, fish began to die. In a large aquarium, this process will occur many times slower and you can remove the dead snail from the can without harming the fish.

3. In small aquariums there is little space for free swimming, and, accordingly, not every favorite decor can be placed in it.

4. Ample opportunities for design and decoration.

5. A large aquarium can hold a lot of large fish or a large number of small ones, it allows you to contain various types of fish.

With all the advantages of large aquariums, it is sometimes not possible to install it. Small aquariums are great for apartments, country houses or hostels, as well as for the second floors of private houses. Large aquariums weigh a lot, they are difficult to transport, take up more space, and in unforeseen circumstances cause more damage.

The biggest advantage of a small aquarium is a financial issue. Aquarium, equipment, scenery, soil, plants, the cost of electricity, the treatment of fish cost much less.

Before acquiring you need to properly assess the benefits of both large and small aquariums. Answer yourself the question: "How much aquarium would you like and is there a possibility to contain such a volume?" If finances are not important, and you do not often move, then the choice is obvious. And if you do not want or can not afford a large aquarium, then a small aquarium is what you need for you. In any case, the main thing - comfortable conditions for the maintenance of fish.


Selection and compatibility of different types of fish

In order to determine which fish you like, just read the literature, watch videos, go to a pet shop or to the bird market. Make a list of the types you like most.

This list should be a little more than you will purchase. Subsequently, it turns out that not all fish are suitable for your aquarium, some are incompatible with each other, parameters or temperature conditions will not work for others. But the abundance of species in the fish market will allow you to finally form a list of the inhabitants of your aquarium.

To understand how roomy a settled aquarium is, you need to carry out simple calculations. In various information sources they vary. Some are based on the oxygen demand of adult fish, given the surface area of ​​the water. Some cold-loving freshwater fish require 192 cm2 and tropical ones 64 cm2.

Other calculations averaged justify - one liter of water is needed per cm of body length of an adult individual (for example, you can run five fish of 4 cm each in a 20 l aquarium)

For a marine aquarium, for each fish 2.5 cm long at least six months old, 18 liters of water are needed, and for later age 9 liters.

Some fish species share the size of the aquarium geographically and protect their habitat from other representatives. This leads to a decrease in the number of inhabitants in it.

At the simultaneous maintenance of different species need to pay attention to even the acquisition of fish. The key to a good selection of pets for an aquarium is the following conditions:

  • similarity of climatic conditions (it is impossible to combine freshwater and saltwater fish, freshwater and brackish water bodies);
  • about the same hardness and acidity of water;
  • the same temperature;
  • similar conditions on the speed of flow, soil quality, the presence of thickets and shelters, lighting.
Fish are doing well in conditions as close as possible to their natural habitat.

When settling an aquarium, it is necessary to take into account the preferences of the species in relation to their location in the layers of the water column, and try to evenly distribute them.

The size and temperament of the fish matter

Important parameters for species compatibility are their size and temperament. Of course, it is impossible to contain predators and herbivores in one aquarium, otherwise the latter will become food. In the wild, larger fish eat smaller ones.

Even if you only have herbivorous fish, you need to check that the size of the smallest fish is larger than the largest mouth opening of the fish in the aquarium. This will avoid unnecessary casualties.

Certain fish are territorial and do not let other species close to their habitat. There can be many reasons:
