How to choose an aquarium for fish


❶ How to choose aquarium fish :: the most simple aquarium fish :: Aquarium fish

Tip 1: How to choose aquarium fish

Aquarium is considered to be the most beautiful design element of any room. An unprepared person when buying his inhabitants can make a lot of mistakes, so let's figure out how to choose the aquarium fish.

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

The most common absurdity that novice aquarists commit is to keep predatory and harmless fish together, as well as keeping fish that are not intended for home use. If the fish is not predatory, but large, it can easily swallow the fish of a smaller size.

Therefore, the first thing to do to the future owner of the fish is to study the largest possible number of varieties of aquarium inhabitants. The easiest option is to stop in choosing medium-sized fish, most likely, they will not bring much trouble (the most simple Guppy in the care is beautiful fish with golden scales).

In order to choose aquarium fish, you need to determine the place of purchase. Now, they are easier to buy at the pet store, but, as elsewhere, there are leaders and outsiders in this area. The quality of the same product in different places can be very different. Read reviews about the store, chat with experienced aquarists, and only then draw your conclusion. Having visited several stores, you will already accurately determine healthy fish from patients, get acquainted with a possible assortment of accessories for the aquarium, talk with sellers. This will give you the opportunity to get personal, invaluable experience.

Consider a few signs of a competent store. The first is the cleanliness and order not only of the aquarium, but also of the store itself. If you see that there is a “K” on the aquarium, this means that the fish in the aquarium are infected and not sold. Ask the seller, for what reason it happened, and whether the disease of fish in quarantine, affect the health of "neighbors". The fact is that in most fish shops they fish with one net, although according to the rules, it must be disinfected.

Among other things, each aquarium must contain complete information about its inhabitants, if any, then the store can be considered qualified.

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: 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.

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.

How to choose fish, if there is no experience yet?

Aquarium fish for beginners must withstand fluctuations in the parameters of water in a new aquarium and resist diseases caused by stress. Behavior is also important - peaceful, livable fishes are the best choice for a beginner. Often forget about such a factor as the ability of the fish to adapt, not in terms of water, but in terms of the new environment and new neighbors. You can also read: 10 best fish for beginners

New aquariums are very unstable due to the fact that they did not form the necessary microflora (beneficial bacteria that remove harmful substances). And even if you add bacterial preparations (they are sold in pet stores), conditions may not be suitable for delicate fish.

Some fish, especially large ones, live well in practically empty aquariums without décor and neighbors. To others, such conditions will seem terrible and they will fall into stress, despite the excellent parameters of the water, they will fall ill and die. For them, the presence of other fish in the aquarium is a sign that the environment is safe. So, a good choice for a beginner aquarist - a fish that is simple, disease resistant, livable, active and not aggressive.

Find out the parameters of your water

To know exactly the condition of the water in the aquarium is very important, in order for it to be in its normal state, it is necessary to periodically measure the level of Ph and hardness. Knowing in advance what kind of water you have, you will be able to choose the species that are suitable for you, since for some fish the parameters may not be suitable, and if they are planted in such water, the fish may die. Now you do not need chemical education to do this, it is enough to buy a set of tests in the pet store. Better drip, they are more accurate.

Read about fish before shopping.

Unfortunately for beginners, they often lie and sell incompatible species, either fish that are not suitable for beginners, or very large species. Sellers are not conscientious and in order not to become a victim of fraud, you need to prepare.
Choose several types of fish that you like, you can see in pet stores or in the market. And carefully study the information about it, the benefit now is the Internet. This will give you a lot of experience and an understanding of whether this fish will suit you. The main questions are the size to which the fish grows, the character, the requirements for the parameters of water, and how to stick - singles, in pairs or schools?

Think about the future

Most of the fish you buy in the future will grow, change behavior or even color. Therefore, you should know exactly what a cute little fish will turn into with time, and whether there will be enough space for it. Do not buy fish that will outgrow your aquarium, even if you are sure that this aquarium is temporary and you will definitely buy a larger one. A glimpse into the future will also help you draw attention to the views that you did not find attractive. For example, the iris in adolescence is a nondescript fish. But when they grow up it is a bright and very beautiful fish that adorns any aquarium.

Be careful with deformed species.

A careful study of the fish that you liked at first glance may surprise you in order. For example, when buying a three-hybrid parrot for the first time, few people know that it is the result of artificial selection of three different species of fish. And that its unusual shape is the result of deformation of bones and internal organs. If they knew, they would probably refrain from buying.
Now there are a lot of fish of unusual shapes and colors. But, often, this is all the result of breeding and interference with nature. Deformed skeleton, organs and low immunity, this is the result of the intervention. Avoid these types of fish in the initial stage.

Also, do not take fish whose color seems too bright. Unscrupulous sellers specifically stimulate fish before selling, and after all being in the cramped and bustle of the market, stress is for fish. And usually she reacts to him becoming less bright than in an aquarium, and not vice versa.

The fish grow as much as the aquarium allows, but at the same time it has deformed internal organs, health problems. As a result, the skeleton curls, the immunity almost disappears and instead of a beautiful fish you get a crooked freak

Most of the fish will grow to the maximum redistribution, perhaps a little less than in a spacious aquarium. For example, a shark ball that grows up to 30 cm in a small volume can grow up to 25 cm.

Tips for choosing the first fish

Avoid fish with a specific diet — usually feed, the main source of problems in an aquarium. The first 6-8 months you need a fish that will be enough for the usual feed - cereal, for example. After six months, the diet can be improved and diversified as wide as possible range of feed.

Do not buy too many fish at once. Although an aquarium with several fish does not look very spectacular, try to add fish slowly, without risking losing everyone at once from an illness, for example. A rule of thumb is no more than six small fish per week.

Ask the store how long the fish are kept in the show tank. Recently added it is better not to take, two transplants in a short time, too much stress and can lead to problems.

  • 10 tips:
  • Look for a friend aquarist, what would he give you advice
  • Googling about fish before you buy it
  • Do not buy on impulse.
  • Always know to what size the fish grows.
  • Write the list of fish you want now and in the future.
  • Find out the water settings in your tank.
  • Remember, adult fish can change dramatically.
  • Avoid deformed and artificially bred fish.
  • Make sure that the conditions in the aquarium are suitable for your future pets.
  • Do not buy too many fish.

Popular fish, for example, guppies or neons are actually far from the only option for beginners. In order to choose the right aquarium fish, it is important to understand the difference between the one that takes root well in the new aquarium and the one that will hurt.


So, now look at the guppies, especially their pedigree forms. Natural guppies, strong and hardy like no other fish. But, intensive crossing, mixing of related breeds led to the fact that the pedigree guppy can die from the draft. Inbreeding, the lack of natural selection, almost sterile conditions in the aquarium, led to the fact that the guppy's immunity is extremely weak. And the slightest bacterial infection, sometimes mows the aquarium completely.

In well-balanced aquariums, pedigreed guppies live for quite a long time, up to two years. But in the new aquarium, the balance is too weak to start with this fish. Other live beetles, however, are quite strong fish and are quite suitable. Even purebred guppies are a good choice.


The second most popular fish is neon. Wonderful, beautiful fish, but a little timid and sensitive to water fluctuations, as well as to diseases. In a stable aquarium, a flock of neons can live for several years without any problems, but in a new one it can melt in a few months. Other small tetras, the same timid, if they are not kept by a flock of ten individuals, and it is better to buy them later.


Feed problems

Somiki, as a rule, corridors are often bought in a new aquarium. Why don't they fit? After all, it is a peaceful and accommodating fish, which tolerates various conditions quite well. The problem is that they need to be kept in flocks, and fed with various sinking feeds. And in a new aquarium, feeding a group of fish with food rich in protein can lead to overfeeding, and a sharp increase in toxic substances - ammonia and nitrates.

Other soybeans that feed on algae are antsistrusy, loricaria, and otozincluses They just will not have enough food.

Just a couple of types of fish that can be problematic:
Hybrids - fish obtained as a result of breeding, as a rule, have a weakened immunity and are demanding of conditions. For example, discus (never take them if you are new to aquarism), bright forms of guppy.
Large species of fish are usually aggressive, they should also be the first to get them.

What remains? Yes, many species. For example:

Guppies of simple breeds are an amazing example of unpretentiousness.
Mollies - coal black beauty and not demanding of conditions.

Large gourami, such as marble. They can live practically without oxygen in the water, but are more suitable for aquariums with a large number of plants and shelters.

The males are very beautiful and undemanding. Just do not plant them with their own kind!

Sword bearers and petilia are active, vibrant and livable.

Danio - grace and small size.

A good choice is also fish of the iris family, these are peaceful and undemanding fish, although they prefer hard water and active neighbors. Most iris irons reveal their potential in color a few months after being placed in an aquarium, and at first they may look nondescript.

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. В небольших аквариумах места для свободного плавания мало, и, соответственно, не всякий понравившийся декор можно в нем размещать.

4. Широкие возможности для дизайна и декорирования.

5. Большой аквариум может вместить в себя много крупных рыб или большое количество маленьких, позволяет содержать разнообразные виды рыбок.

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 sacrifice.

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

  • suitable food supply,
  • the spawning ground arrangement (the couple who carry out the treasure jealously guard the nest),
  • the presence of water turbulence with optimal temperature parameters, etc.

Differences in species manifested in modes and methods of feeding. For example, somobraznye eat food from the bottom, petsliiliformnye - from the surface. Some kind of fast and agile, and some - slow and unhurried. Fish require different food, and if you do not like it, it is better to choose pets with the same way of feeding. If you do not follow the feeding regime, then some species will be hungry and others will be overfed, which will lead to a reduction in the life span of all inhabitants.

Often, fish are acquired that have not reached puberty, which leads to incorrect judgments about their temperament. Therefore, in order to fully determine whether this fish suits you, it must grow and be in comfortable conditions. Of course, if any representative is unnaturally pugnacious, cuts off fins or clogs other fish, it should be isolated.

Fish, the most suitable for beginners

This topic is hot and is discussed in many forums. There are many types of fish that require minimal maintenance. This allows you to choose the most suitable pets for each novice aquarist both in a variety of colors and in size. The aquarium can be equipped with beautiful relief and plants, and originality will give a contrast to the color of the fish.

Very often, beginners choose viviparous fish such as swordtails, plazii, guppies, mollies, etc. And this is an excellent choice. They have a good survival rate, are easy to maintain, are active, have a long lifespan and do not require strict conditions of detention.

There are some types that are ideal for beginners.

Guppy - fishes of the Petsiliev family, with a peace-loving character, calm and unhurried in behavior. Coloring is very diverse and beautiful. To the composition of the water does not impose requirements. Periodically you need to change the water. Viviparous Easily distinguished by sex. Males are much smaller, more beautiful and brighter. Omnivores. Overfeeding is not recommended. Easily tolerate a decrease in water temperature to 15 ° C.

Swordtails - Family Peziliye. Have more than 25 decorative varieties. In the male, the tail fin has the shape of a sword. Very beautiful fish that does not require special conditions and specific size of the aquarium. Viviparous, easily reproduce. When the fry appear, the parents should be moved to a free container to avoid eating the children.

Gourami - mobile fish, differing in an interesting spotty color, are curious. To other types of fish and inhabitants are tolerated. They can breathe not only air dissolved in water, but also oxygen directly on the surface. Black out.

Somics different external originality. Unpretentious, peaceful, eat any food from the bottom. Clean up the remnants of food uneaten by other inhabitants. Orderlies aquarium. Prefer bottom-living and easy to get along with other species.

Neon - Representatives of the Kharatsin, there are more than 150 species of fish. The most common among beginners are red and blue. The content is simple, undemanding to water. They love the space, the length of the aquarium should be at least 50 cm. Excellent jumpers, so you need to cover the surface of the water with glass or a lid.

Danio - schooling, bright, beautiful fish. Aquarium is needed with a length of at least 55 cm. Very mobile and like space. Requires regular water changes and good aeration. Great jumpers, so you need an aquarium with a lid or glass. Prefer good lighting and clear, clean water.

Barbusses - schooling fish. There is a huge variety of species (more than 200). In the schooling content of peace. Very active. It is not recommended to keep them with fish, the tail of which has thread-like or voile forms. They love floating plants.

gold fish - a representative of the carp family. It is very popular, but it requires a large volume of aquarium (per adult of at least 35 liters of water). Prefers clear, clean water and requires its regular substitution. Very voracious, so you need to be careful with feeding. Prone to overeating.

Antsitrus - somobrazny, herbivore. Very good orderly, nibbles small shoots from the glasses of the aquarium. The oral opening resembles a suction cup. Males have a large number of mustache. Peaceful. It is recommended to feed tabletized plant spirulina.

Presents the most common, unpretentious, do not require special care fish that are suitable for beginners. But this does not mean that they do not need to be watched, to know their preferences, the temperature of the water, etc.

Tips from personal experience

  • When buying, it is better to purchase young and healthy fish (active, without external signs of disease).
  • Before launching into the aquarium, it is better to stand for 3-5 days in a separate container.
  • Buy better for 5-10 pieces, it will avoid same-sex.
  • You need to choose 2-3 types of fish. 1-2 basic, third extra. For example, mollies and gourami as the main species, and ancytrus as an additional. The first two types are active, mobile, well contrasted, and ancytrusians will be orderlies.
  • It is best to buy aquarium, equipment and fish in a bird market from one seller. He will remember you, and you can take his phone number without any problems and consult on unclear questions.

The right aquarium: what you need to consider when choosing, running and arranging


More than 7 thousand people a month ask this question: “What kind of aquarium is right?”, “How to create it?”, “What is right and what is not in an aquarium?”.

So let's try to deal with you in this matter. And we will try to bring a certain qualification of the correct aquarium.

To begin with, let's define the concept - the correct aquarium.

You must agree, there are so many nuances and criteria of correctness: What form should an aquarium? What volume? What kind of fish? What should be in it at all and what should not be?

I think in this matter you need to push off from a certain constant and understand that AQUARIUM is a closed ecosystem, an imitation of the natural conditions of fish habitat.
From the above, it can be made simple that the RIGHT AQUARIUM is a body of water as close as possible to the natural habitat of fish. That is, in such an aquarium should be:
- Complied with all the parameters of water for a certain type of fish;
- the landscape and design of the aquarium should be as close as possible to the natural habitat;
- there should be enough filtration, aeration, lighting and purging;
- care for fish, which carries people, should be as close as possible to the actions of "Mother Nature";

Now, based on the definition, you can easily display the main parameters

1. VOLUME AQUARIUM. Everything is obvious here - the bigger the aquarium, the better! And this is not because a huge aquarium can boast or it will look "rich." Not! Simply, the more a closed ecosystem, the easier and better biological processes take place in it, such a system is easier to set up, such a system is easier to maintain. We can say that such a system is more stable than in a small aquarium.
Many aquarists on the Internet give an example, that in a small aquarium it is much more difficult to maintain water temperature stability than in a large aquarium. And it is true. And if you drop even deeper? It can be said that in a small aquarium it is harder to adjust the parameters of water, it is harder to dissolve a colony of useful nitrifying bacteria, more often you need to clean and change water, etc.
Alas, the living space and the financial component does not allow many to acquire a large aquarium. But, still for a novice aquarist can advise an aquarium of 100 liters. So to say - this is the initial volume of the correct aquarium.
2. FORM AQUARIUM. Here in this article - "WHAT AQUARIUM IS BETTER", examples of various forms of an aquarium are given - their infinite number. However, the most appropriate form for an aquarium is rectangular or panoramic. At the same time, you need to take into account the characteristics and characteristics of the fish. Some need a long aquarium, some tall.
The worst form of aquarium is considered - round. Such an aquarium is not convenient for placement of equipment, it is not convenient for maintenance, and even the spherical glass itself distorts the image of the reservoir.

3. EQUIPMENT FOR AQUARIUM. Properly selected aquarium equipment is the key to success. The thermostat, aeration, filter, lighting should be of sufficient volume and quality. Based on the characteristics of a particular aquarium and specific fish, you need to select equipment with a certain specificity. For example, the filters can be internal and external, multi-section or single-rack, with a compartment for ceramics (biofiltration) or without it. For more information about filters, see the article - A good filter for an aquarium. The same applies, for example, to lighting. If there are plants in the aquarium, the aquarium lamps must be of sufficient power and the required spectrum.

The habitat of fish is different. Some fish live in the thickets of valisneria, some live near the rocky shores, some even live in the standing water of rice fields.
Therefore, when arranging the “right aquarium”, first of all you need to start from the needs of the fish and their natural habitats. For example:
Angelfish are South American cichlids that live in bodies of water with rapidly growing underwater and surface plants. That is why, as a result of centuries of evolution, the body of an angelfish has acquired a flat shape - so it is more convenient to swim among the "underwater forest". Obviously, the most appropriate design for an aquarium with scalars will be an aquarium densely planted with a variety of vegetation, especially long-stemmed, tall plants, for example, vallyseries.

African cichlids - the exact opposite of the scalar. Most African cichlids live in the so-called "stone deserts", where there is not a small plant. The rocky shores of African rivers, completely covered with rubble, caves, grottoes. Such a landscape helps the fish to survive and shelter from the enemy; in the caves and minks, African cichlids hatch and hide their offspring.
Therefore, the right aquarium for such fish will be a reservoir, equipped with numerous stones, grottoes and snags.

Labyrinth fish (cockerels, gourami, macropods) are the South Asian guests of our aquariums. They live in the rice fields, where there is little oxygen, and the water is stagnant. Living conditions have taught these fish to breathe atmospheric air, which they capture from the surface of the water. Therefore, the aquarium for them should not contain plants that float on the surface or completely close it. Otherwise, the fish will suffocate. In addition, many labyrinths need shelters - caves.

5. PARAMETERS OF WATER AND CONDITIONS OF THE CONTENT OF FISH. Everything is simple - the parameters of water temperature, hardness, "acidity", etc. must fully meet the needs of this or sometimes the type of fish. Actually, these same parameters are of first priority when deciding on the compatibility of fish - you cannot keep fish, for which the water parameters are different. See also the article AQUARIUM WATER - parameters dH, pH, rH.

Proper care of the aquarium

The aquarium is not a picture, hanged and admired. This is a daily care and care. It is difficult to call an aquarium right if the fish are fed only dry food, and aquarium plants are not fed with trace elements. Do not forget about the usual care for the aquarium: changing the water, cleaning the walls of the aquarium, siphon of the soil, washing the filter, etc.
There are other nuances that speak about the correctness of the aquarium. For example, the presence of a UV sterilizer, ozonizer, cooler, cooling system or CO2 system will speak of you as an advanced aquarist. In addition, many aquarium devices can be done with your own hands! The exact same phyto filtering that anyone can do will have a favorable effect on the health of any aquarium.

Based on the foregoing, you can derive some formula

This aquarium of 100 liters, rectangular shape.
With the right equipment:
- aeration (preferably versatile)
- filtering (multistage)
- heater (with thermostat)
- lighting (sufficient power and the desired spectrum)
Design and arrangement of the "right aquarium" as close as possible to the natural, natural habitat of a particular type of fish.
In the correct aquarium, the rules of compatibility of aquarium fish are observed, the parameters of water and the status of hydrobionts are regularly monitored.
In the correct aquarium, there is more specific equipment that improves the quality of the reservoir and the life of the fish.
And most importantly, aquarism, and any other human activity, will always be right - if it is done with love.

Choosing an aquarium for fish :: Aquarium fish

Choosing an aquarium for fish

So, you decide to do aquarism. The place for the aquarium has already been chosen, its future inhabitants-fish, too, it's up to you to get the aquarium itself. But how not to get lost in a huge range of models and options?

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

Shape and size

Probably the first thing that aquarists think about is the size of the future aquarium. If you are still new to breeding fish, start better, of course, with a medium-sized aquarium. However, you should know that caring for a small aquarium, paradoxically as it may sound, is much more complicated than for a large one. Why? The fact is that the microclimate of the aquarium and the comfort of its inhabitants are largely determined by the ratio of oxygen dissolved in water. In the process of breathing fish emit carbon dioxide, which also enters the water. In addition, water is polluted by waste products. Consequently, the smaller the area of ​​the aquarium, the faster the water will be contaminated and the more often it will have to be changed. And the larger the aquarium, the more comfortable the fish will feel in it.

The shape of aquariums today is also very diverse. You can order a design of any complexity and give free rein to your imagination. But, coming up with an intricate design for the future of the aquarium, do not forget that it should fit into your interior and be easy to maintain. It is most convenient to clean rectangular aquariums, they are today the most popular because of their versatility: such a house for fish will decorate any interior and take up the minimum amount of space.

Material and method of manufacture

An important detail is the material from which the aquarium is made. It can be glass, plexiglass or asbestos cement. Glass aquariums are made of two types: frame and frameless. In the first case, at the junction of the glass sheets, the construction of the aquarium is further strengthened with metal corners. Frame aquariums are heavier, but also stronger than frameless ones. If you do not want extra costs, and too much strength is not required, you can get by with the classic option - a frameless aquarium. Its parts are connected using silicone. It is the frameless models that amateur hobbyists most often prefer.

But plexiglass allows you to bend the walls of structures at different angles and make them rounded and asymmetric. Such aquariums are usually made for offices or studios, but they are much more expensive than ordinary rectangular. Asbestos-cement aquariums are practically not used by amateurs, as a rule, they are made for large volumes of water in zoos or oceanariums.

Choosing an aquarium for cockerel fish

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?

What aquariums are suitable for cockerels

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.

Are there special aquariums for 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.

Which aquarium is better to choose and buy


Indescribably pleased with the fact that you decided to get an aquarium. This is the right choice! An aquarium at home or in the office is not only a design subject. Aquarium and aquarium world is a hobby, passion, relaxation, positive mood, new knowledge and a new world.

What can I say !!! Aquarium is cool!

But here, when there was a desire to purchase an aquarium,

there is another question


In this article I will not read you notations, as some do - they say, read the books first, study the essence of the issue, and then make a decision on which aquarium to choose.

Here, I will try to concisely give advice on choosing an aquarium, posting photos of aquariums, tell which aquariums are in general, well, ask people in the comments to tell what their aquarium is.

Recalling the purchase of my first aquarium, I want to say that I did not think at all, which aquarium should I choose. I just "broke the piggy bank and bought some money for it, I bought it." And enough for a panoramic aquarium firm TM "Nature", a volume of 35 liters and with a glass lid, without lighting.

What I mean is that the choice of an aquarium often comes down not to what is better, but to the question of individual capabilities. Therefore, in the first place, you need to decide on a budget, and it must be borne in mind that with the purchase of an aquarium alone, the spending will not end. Initially, at least to the aquarium will need to buy: a filter and aeration, thermostat, soil, and of most fish. Also it would not be bad to buy immediately: decor, plants (live or artificial), aquarium equipment (a net, siphon, glass cleaning magnets, etc.), after all, it would not be very bad to buy drugs to stabilize the aquarium water and biosystem settings, but they are also not cheap.

The second thing you need to take into account is the place where the aquarium will stand! Much depends on the location of the aquarium: its volume, shape, purpose, and other strokes. For example, if you decide to put an aquarium in a corner of a room, then in my opinion it is better to buy a corner aquarium (with three sides). Such an aquarium will fit well into the interior, will not take up much space, moreover it will give a good panoramic view of the aquarium.

Well, perhaps the third very important point that needs to be taken into account when choosing the best aquarium is the need to think in advance: what and who will be in the aquarium. This is due to the fact that the maintenance conditions of the aquarium inhabitants are different. For example, some fish need a large volume aquarium, others need a small volume, but preferably a long one, some need an aquarium cover, others do not, and so on.


Analyzing the statistics on the Internet, as well as from personal experience, we can recommend one of the most popular aquariums:

Volume: 200 to 250 liters.

The form: Rectangular, panorama or convex front glass. TM "NATURE".

Aquarium price: depends on the configuration, without a cap and tube - $ 90-100. C from 200 $.

Who is in the aquarium: the volume of such an aquarium allows you to have virtually any fish, except for particularly large ones.

Other useful information: The parameters of such an aquarium meet the needs of many people, and the price pleases. For example, a similar aquarium company "Aquael" with a lid, but without a stand is worth - $ 340, as they say, feel the difference.

Of course, if funds allow, then you certainly need to take "Aquael", they are much better than Kharkov "Nature". But, I want to note that I have one of the TM "Nature" aquariums already 10 years old and only pleases, there is no global difference between Aquael, except prestige))).

What else should be considered when choosing the best aquarium.

- All aquarists, in one voice, I recommend initially to take a large-volume aquarium (from 100 liters). It is right, because such an aquarium is easier to care for, it is easier and faster to adjust the biobalance, adaptation and living aquarium inhabitants is better. In general, there is less trouble!

However, do not think that small aquariums are worse, no! Just such aquariums need a little more attention. And taking into account the fact that many people do not allow living space to take "oceanariums," there is a reason to start with a small aquarium. In addition, in a small aquarium, you can “practice” and see if you are interested in aquariums in principle or not, “get a hand”, and therefore decide whether to take a large aquarium or not.

- On sale there are aquariums of the round form, various volume. As a rule, Goldfish are planted in such aquariums. So, I hasten to warn you and say that such aquariums are not very convenient to maintain, moreover, their image is distorted by a spherical shape, and the fish in such aquariums are bad. Often, having suffered from such an aquarium, people make a decorative pot of flowers out of it. At this aquarium ends and begins floristry :).

- On sale you can also find high, but not wide aquariums, made as aquarium paintings. Such aquariums are relatively inexpensive, but they are not the best for the title of the best. Firstly, because they are hard to care for, and secondly, aquarium fish will be bad in them, because for them the main length and width of the aquarium, and not height. Height also plays a role, but in combination with length and width.

- The most common form of aquarium is a rectangular, but you can also recommend a panoramic aquarium or aquarium with a convex front glass. Panoramic aquarium consists of 6 faces (walls) - which gives more viewing angles. A tank with a convex front wall gives volume and looks more interesting than an aquarium with straight glass.

- When buying an aquarium, pay attention to its cover. Covers can be plastic, wooden or glass. The main question is the lighting installed in the cover, which, as a rule, is usually not enough for aquarium plants. If your aquarium will have a lot of aquarium plants, the issue of lighting is best resolved immediately. Pay attention to the fluorescent lamps on them: the number, power and characteristics.

The lack of lighting can be solved in two ways: self-adding lighting (add. Lamp or diode tape) or the initial purchase of a glass cover, and to it the "right amount" of lighting.

- When buying an aquarium, you should pay attention and carefully check it for the presence of chips and microcracks. Consider that even the smallest crack under the pressure of water will sooner or later turn into a huge hole. This rule should be especially followed if the aquarium is purchased through an online store. Movers do not really stand on ceremony with the goods delivered. Carefully check everything when delivering the aquarium to your home.

Talk about choosing the best aquarium can be a lot, but as they say it is better to see once than to hear once. Therefore, we proceed below to a visual study of the issue.

Now let's visualize

most popular forms of aquariums







Types of aquariums by purpose

All aquariums can be divided according to their purpose. I think this information will be useful for you: it will help to determine the aquarium terminology, and also help you choose the best aquarium based on your needs.

General aquarium - it is intended for keeping fish of various types. As a rule, in such an aquarium fish are selected according to the principle of compatibility. Most aquariums are just common aquariums.

Species Aquarium - an aquarium in which fish of only one species are contained. A characteristic example is an aquarium with discus. DISCUSSIONS They are called kings of the aquarium and as a rule they are kept separately because they are expensive, large and fastidious to the conditions of detention.

Spawning aquarium - it is intended for cultivation of fishes, spawning, incubation of caviar and cultivation of fry. As a rule, such aquariums do not have a large volume and in such aquariums they create special conditions (temperature, lighting) and certain water parameters (dH, pH), which contribute to the spawning of certain fish. Spawning aquarium can also be divided into incubator - it is intended for cultivation of caviar, fish larvae, nursery aquarium - it is intended for cultivation of the grown up juvenile fry.

In terms of shape and function, a spawning aquarium is no different from other aquariums, it is needed exclusively as a separate body of water.

Thus, if you want to breed fish, in addition to the general or specific aquarium, you must also buy a spawning.

Quarantine aquarium or medical - as well as spawning is a separate reservoir, but intended to check the newly purchased fish and treat sick fish.

In such an aquarium, a quarantine for new fish is arranged in order not to infect the common main aquarium. The need for quarantine is due to the fact that even if you bought a seemingly healthy fish, signs of illness may appear in a week. During this period, the fish in the quarantine of the aquarium are checked "for lice", and, moreover, adaptation measures are taken - they gradually add water from the main aquarium to the quarantine. Adaptation is needed because Some fish do not tolerate abrupt changes in the parameters of the aquarium water, from which die a week later.

Quarantine aquarium is especially needed if you purchase fish in the Bird market, as a rule, in such markets there are many contagious and sick fish. In pet stores, this risk is less, but still it is.

In addition, quarantine aquarium can be used as an aquarium for the treatment of diseased fish. Лечение можно проводить и в общем аквариуме, но во-первых Вы понапрасну будете травить здоровых - не заболевших рыбок химией, во-вторых на химию и лечебные препараты могут плохо отреагировать аквариумные растения, да и вообще нарушится биобаланс и микрофлора аквариумной воды, кроме того будет оставаться риск повального заболевания всех рыбок.

Поэтому заболевших рыбок всегда рекомендуется отсаживать в карантинный аквариум и там проводить индивидуальное лечение до полного выздоровления.

Аквариумы также можно разделить на:

Biotope - in it imitate separately taken underwater landscape (lake, stream).

Dutch - Aquarium designed for aquarium plants, it is also called "herbalist".

Geographical - in such an aquarium contain fish from one region.

Freshwater, saltwater, marine aquarium - Most aquariums are freshwater bodies of water, but there are aquariums that contain saline or marine fish.

For general development, it can also be said that the structure can be divided into: frame, frameless, asbestos cement, Plexiglas.

And of course, there is still
shrimps, aquariums for turtles, newts, frogs and others.
