How to get aquarium fish

Aquarium with ornamental fish is a great decoration for your interior. However, we must not forget that there are living creatures that need care and feeding. Aquarium can also be a good lesson in responsibility for your children.

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


1. First you need to choose the aquarium itself. You can purchase ready-made option in the pet store. And you can order an individual project that fits perfectly into your interior. When buying, pay attention to tightness. The best option is a one-piece aquarium, as you can not be afraid of water leaks. If the future home for fish is a few glued sheets of glass, in any case, you will need a pallet. Also inspect the aquarium for defects: cracks, scratches or any other flaws that can cause sudden damage.

2. At the pet store, purchase special river sand to fill the aquariums. The amount of sand depends on the volume of the tank, here you can help the sales assistant. To decorate the aquarium, you can buy seashells and pebbles, stylized jugs and other decorative items. If you want to plant live plants in an aquarium, you should not do it right on the river sand. First, fertilize the soil with well-boiled peat, add river clay and then plant algae. Many plants are not required, as they grow quickly and can fill an entire aquarium.

3. Vessel for fish it is necessary to fill with filtered water (ordinary water from a tap that passes through a household filter) or raw distilled water (fish do not take out chlorine). It is necessary to pour water very carefully so as not to lift the river sand. Usually use a rubber medical tube, one end of which is inserted into the aquarium, the other - into a vessel with cooked water. With a large volume of aquarium water purification is a special filter. You will also need an apparatus for enriching water with air.

4. The next step is the purchase of the inhabitants themselves. You can bring them home in a regular bank. Rinse it with pre-boiled water without detergent, fill it with half aquarium water. You can also use a plastic bag, after making sure that it does not pass air. For confidence, it is better to place one package in another.

5. Do not forget to buy food for your fish. The most common species: bloodworm, cyclop, daphnia, tubule and dry food - all this can be purchased at any pet store. Store it in a dry, dark and cool place, so as not to blinded and spoiled.

6. The choice of a particular type fish depends entirely on you. The most unpretentious aquarium inhabitants are guppies - small colorful fish. They do not need a lot of food and get along with other inhabitants. You can also make fish-beretus They have a nice black and red color, very calm, not aggressive. Good neighbors for fish snails and a small catfish will become - in addition to the decorative function, they will clean the aquarium from contamination. When choosing more exotic species, find out if they need special conditions, and what neighbors can you share with them.

Aquaria for beginners: important tips

A beautiful aquarium in the house brings joy to our lives during the contemplation of fish and perfectly affects the psychological component. Each novice aquarist unwittingly wonders where to start, to get everything right for the aquarium, run it right the first time and prevent the fish from dying.

Choosing a home aquarium

Before acquiring a tank for fish, it is necessary to carefully consider its design and shape so that it fits into the interior of the room as naturally as possible, does not interfere with its basic purpose and is located in a place convenient for viewing.

By design, aquariums are on a stand, on legs, suspended, angled, frame and frameless. In form, they are represented by more than a wide choice, the main of which are:

  • spherical (round);
  • cubic (square);
  • parallelepipedal (rectangular);
  • parallelepipedal with convex viewing glass (panoramic);
  • prismoidal (with a regular polygon of the bottom, as a rule, high, for a floor installation);
  • pyromidoidal (triangular, for closed-type aquariums).

The main parameters for choosing a tank for keeping fish in a novice aquarist are the following factors:

  • correct installation, which should allow various manipulations during operation (removal or installation of the cover and backlight, feeding fish, planting plants, cleaning the filter, bottom siphon, etc.);
  • the exclusion of direct sunlight on its surface;
  • the number and size of the aquarium population (the required volume of the aquarium depends on this. If there is no certainty for specific fish, then take at least 1 liter of water per 1 cm of adult fish, i.e. if you want to contain 10 fish 8 cm long, you need an aquarium more than 80 liters, it will avoid overcrowding and allow it to develop well and feel comfortable for its inhabitants).

Aquarium accessories

Together with the aquarium offer covers with integrated lighting and cabinets for them. If there is no specific place to install the aquarium, then you can use this offer. A lid for a backlit aquarium will prevent many species of fish from jumping out, reduce evaporation of water into the atmosphere of the room, and also provide artificial lighting for the plant and allow you to control the length of the day in a pond. The cabinet is suitable for storing all sorts of accessories (a net, tubes, suckers, feeders, literature, etc.), feed and other things related to the aquarium.

Aquarium equipment

There is a standard set of equipment for aquariums:

  • Illumination (the choice of lamp power and the duration of illumination during the day depends on the inhabitants and plants);
  • water heater (it is better to choose with automatic temperature control);
  • Aerator and water filter can be both combined and separate (power depends on the volume of the aquarium).

The selection of soil and scenery depends on the inhabitants, but small fractional rounded gravel without sharp edges is considered universal. The thickness of the soil at the bottom should be from 5 to 7 cm, this will allow plants to root well and grow. You can use locks, sunken ships, etc. to decorate and create a unique interior.

The choice of inhabitants and vegetation

Practically all viviparous fishes are suitable for beginner aquarists: mollies, swordtails, petilles and gupias. They are beautiful, elegant, not difficult to maintain and hardy. The content and reproduction of these species will allow you to learn the basics of aquarism while investing minimal financial and time costs.

You can run a few small catfish to the viviparous fish. They differ in coloring, body shape and behavior. Somiki will add refinement to the aquarium and will eat the remnants of food and clean the plants. Antsitrus catfish suckers are perfect.

From low-priced low-priced plants, you can use elodea, valisneria, cryptocarin, and from superficial plants, ichie or duckweed. You can also add lumps of moss to a kladofor or javanese moss.

Running aquarium

Before releasing beautiful fish in the aquarium, it takes about two weeks. One day can be done:

  • laying soil, planting plants, installation of lighting decorations, heating, filter aerator;
  • filling the aquarium with tap water;
  • turning on the heater and filter aerator.

After that, you need to wait a week for chlorine to evaporate from the water during this time. It is allowed to add various normalizers to the water, which improve the water parameters. Before using them, you should consult with competent aquarists or sellers who know the parameters of tap water in your area.

After a week, you can run the first, most enduring inhabitants - snails ampoules, tritons, frogs or shrimp. Often the first are ampulyarii. They have a positive effect on the formation of an ecosystem in an aquarium. Water in a room pond is gaining stability in the order of a month and may become cloudy. Over time, it will clear and be transparent. And only depending on the state of water and the state of health of the ampoule, after about a week you can run inexpensive fish. More information about the first launch of the aquarium can be found here.

From practical experience

There are some general tips on keeping and breeding fish, but it all depends on the specific inhabitants of your aquarium.

  1. It is better to buy a rectangular aquarium without panoramic glass, while its length should be greater than the height and width less than the height.
  2. The volume of the aquarium of about 100 liters will allow you to contain a closed ecosystem (the state of water in the temperature, chemical and biological ranges will be less subject to drastic changes, which will affect the health of the fish), and will also require lower maintenance costs.
  3. Maintaining a constant temperature will save the fish from many diseases.
  4. Overfeeding fish can not be, and better to feed once a day. Food should be varied - live, frozen, dry (if you feed constantly alive, the fish begin to get fat and it becomes difficult for them to multiply).
  5. Change the water in the aquarium weekly with the replacement of up to 30% of the total. Cleaning and siphon bottom in the first month after launch do not need. Depending on the number of fish, pollution of the bottom or chemical indicators of water, these activities should be carried out approximately once every two to four weeks.
  6. The water filter and aerator in the aquarium should work around the clock.
  7. Lighting needs to be controlled, otherwise excessive growth of algae or plants will begin. The duration of coverage per day is in the range from 8 to 12 hours.

How to choose an aquarium will tell experts of the program "Cheap and Angry" (Channel One):

Should I start an aquarium and fish, what disadvantages should be taken into account?

Should I start an aquarium, what disadvantages should be taken into account?
Do you really need these fish?

If you think that this is another article that convinces and gives you fish and an aquarium - you are mistaken! On the contrary, in this article I will try to uncover all the aquarium horrors and discourage any desire to start fish.

So, let's go !!!!

1. AQUARIUM ZHUZHIIIT. Yes Yes exactly! Aquarium equipment (filter, aeration, compressors, etc.) create an incredible noise, especially at night. And if you buy more cheap Chinese equipment, then the effect of "bikers in the night" is guaranteed. I have aquariums in the kitchen and in the living room. And when guests come to me, I don’t turn off the "hotel aquarium" on purpose so that the guests hurry away))) Of course, this is a joke! But, think, and whether it is necessary for you! Do you have a place where the buzz of an aquarium does not cause wild irritation?

2. In one of the articles “For the aquarium” I wrote that: “fish are not cats and dogs” they don’t need to collect porridges for them ... However, I want to warn you - are you ready to defend and replace the aquarium water weekly to fresh? And this is nearly 30 liters at the rate of 100 liters of aquarium weekly. Are you ready to clean it at least once a month (clean: aquarium walls, soil, filter, aeration, etc.)?

3. I completely forgot, the aquarium, aquarium equipment, fish, aquarium preparations and gadgets - WORTH GOOD DAYS! Do not think that buying an aquarium will end your expenses. A normal aquarium now costs $ 1000 + a pedestal for it, somewhere around $ 400 + equipment and stuff ... it all falls to $ 2,000 instantly. Think !!! Maybe all the same with this money to buy a good SLR camera?

4. FISHING SICK AND PAIN. Especially at the beginning! Do not think that having bought fish once they have, you will live 30 years. And believe me, gnawed fish corpses are not the best sight!

5. AQUARIUM IS A STRONG GLASS PIECE! The question is where will you put it and where to put children who are worn like mad and climb where it is not necessary?

6. The next aquarium drawback, of course, is not only to treat fish. But, since we are talking about them, I will tell you the following, if you are planning to go on vacation in the summer, then unfortunately you won't leave the one-on-one aquarium. We'll have to leave the keys to the apartment of your beloved mother-in-law or negotiate with dear neighbors! What would they look after your "oceanarium".

7. Well, in conclusion I will list a couple of small worries and drawbacks of the aquarium: you need to feed the fish, the light eats the aquarium, the aquarium can “get stuck”, it is not recommended to install the aquarium in the socle or damp rooms that in the room where there is an aquarium it is impossible to use an air freshener.


Well, then you are welcome to the WORLD OF AQUARIUM FISH!

What kind of fish to settle 10 liter aquarium?

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

How to set the balance in the mini tank?

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

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

See how the ground siphon in the nano aquarium.

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

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

Now about feeding. As you know, overfeeding harms not only the health of the fish, but also adversely affects the quality of water. All uneaten decays, turning into harmful impurities and bacteria. Decay products are deposited on the bottom and reservoir machines, disturbing the stability of the biological environment. Fish should be fed, hunger is also not an option. Один раз в неделю устраивайте для рыбок разгрузочные дни. Добавляйте корм по 4-6 крупиц, какие питомец по силе проглотить. То, что не съел, нужно убрать марлевым сачком.

Давайте для рыбок, которые живут в маленьком 10-20-литровом питомнике столько корма, сколько они съедят за 2-6 минут. Хлопья, живой корм, тонущие гранулы подойдут. Они медленно тонут и не загрязняют среду. Если у вас живут донные сомики, то они всё съедят самостоятельно. Рыбок можно кормить привычным для них полноценным кормом, не нарушая рацион. It is important to clean everything in time.

Which fish is suitable for settling in a mini aquarium?

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

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

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

What you need to get a fish? And how difficult is it to take care of them?

Larisa Dmitrieva

It is better to immediately buy an aquarium of at least 100 liters - the larger the volume, the easier and faster it will establish biological balance, which in the future will be easier to maintain. Soil needed. You need to boil it before pouring it into a washed aquarium (the stench will be terrible, but what to do!) Or bake it in the oven (I don’t know about the stench, did not try it myself), cool it and pour it into the aquarium. Plants are needed - real or artificial. This is up to you. Won in pet stores everywhere artificial - and normal. Just then the fish will have nothing to devour. Be sure to filter the water, air pump (especially if the plants claim.), A thermometer for water, water heater to the desired temperature, lighting. You can buy all sorts of jewelry for an aquarium such as the ruins of a castle or a sunken ship, where the fish can hide. Water can be poured directly from the tap, just let it stand for a day. We must put a sheet of paper, so as not to raise turbidity. We plant plants. These still recommend to plant not in the ground, but in pots - it is easier to care for and change the interior. And leave the aquarium for several days - until the water becomes ABSOLUTELY transparent. This means that biological balance has been established there. Now you can run the fish. This is a separate song, about the intricacies you can talk specifically. Yes, the aquarium should be covered with glass so that the water does not evaporate quickly and the dust does not settle. Everything, the main thing is done. Now you just have to top up the settled water when the water in the aquarium evaporates by a third - that is, we add a third. Feed the fish - dry food or live. This is also up to you. From living there is less dirt, but it is disgusting (in my opinion) and it is difficult to keep it for a long time, and you should often buy new fresh ones. From dry, some are allergic. By the way, many cores aquarium in the room where they sleep, is contraindicated - the pressure rises and also goes like an allergy. Yes, feed also needs a feeder. Sometimes you have to clean the front glass, it is overgrown with algae, but this is rarely, with a cotton swab or a bandage. In general, the aquarium is a thrill, no TV is needed! Highly recommend! Have questions, please contact.


First of all, a fully equipped aquarium (the aquarium itself, light, filter, etc.)
The fish themselves are chosen in such a way that they do not eat each other.
Fish food
And patience every week to wash the aquarium.
Care must be sure otherwise this thing stinks so, and with care it stinks anyway. The most important thing is that there were no allergies!

It all depends on what kind of fish and how much you want. You buy an aquarium. Film with a landscape. stocking up on pebbles. Desirable multi-colored. Right to buy a lock or chest. They need to swim somewhere. Feed them specials. feed.


Desire + money. Aquarium in liters = cost in dollars. Plus fish.
Another tip. If you do not want problems with the aquarium - do not take a small amount. Consider from 150 liters. Care less - the greater the volume.
Good luck! If that - write. Itself once began only with desire and without knowledge absolutely.

Olga Kosareva

First of all, a fully equipped aquarium (aquarium, light, filter). If you do not want problems with the aquarium - do not take a small volume (from 100 liters). Care is less - the greater the volume, the fish chosen for the beginning can be guppies, gurammas, swordtails (not whimsical, viviparous, easy to care for).
Food for fish.
Well, in general, everything, the main thing is not to be afraid to start, after a while you can move on to more complex types. But the main thing is to look through the literature ...
Good luck.

it is not true that the aquarium is vanishing. if only a crocodile lives there and there is fresh meat. wash the aquarium is not necessary. the fish die quickly. it should only be cleaned with a special brush and filter for cleaning. buy a small aquarium, fill the ground with a little algae and buy gupeys, they themselves are not picky and viviparous fish. if the aquarium does not require much care. just do not take the multi-faceted fish there more often get sick! feed don't forget

Igor and

The topic is quite extensive, and not a single answer will contain the necessary basic knowledge. Read a couple of books on aquaristics, and you will reduce the number of problems that you may encounter. Don't be afraid, everything is not so scary. If you are interested, everything will turn out. Care is not difficult if in aqua everything is normal. And the norm depends largely on you. Plant Aqua Good luck.

I want to buy an aquarium and make fish. Where to begin???

Julia Plekhanova

Buy an aquarium of 20-30 liters (some 1500-2000 rub), a compressor (filter) - it purifies water and draws oxygen into it (500 - 600 rub), a thermometer (from 40 to 150 rub), a good book on breeding aquarium fish where there is a photo and description of the habitat (150 - 1000 rubles).
After that, you need to decide on the fish. If unpretentious - then guppies or neons. They need to take pack of 6-10 pieces at once and do not grow large. For these fish, the heater is needed insofar as. If the apartment is warm in winter, the fish will be fine and so. The temperature of the habitat is about 20 degrees. Well, still buy soil, algae, decal.
Other fish are more capricious.

Elena Gabrielyan

The aquarium is preparing to start a whole month. For a beginner, an optimal volume of 50-100 liters. New aquarium before installing, thoroughly rinse the host. soap without additives or with soda. To it you must first of all purchase a filter with aeration and a water heater with a thermostat (the temperature in the aquarium should be 24-26 C) - all the equipment is matched to your aquarium volume. Thoroughly washed (if bought at a pet store) or boiled for 2 hours if they collected themselves) - the soil should be 3 - 5 mm, poured into the aquarium, half filled with water, you can directly from the tap, a filter with an aerator and water heater are installed with thermostat (all equipment must be completely immersed in water), be sure to thermometer monitoring the temperature of the water and the water heater and left in working condition for a week. During this time, you decide on aquarium plants, whether living or artificial and 3 living are the most unpretentious: Arrowhead, Valisnenria, Roghubnik (floating on the surface of the water), Indian fern, (decorations - grotto, snag, scenery - is chosen to taste), plant live plants for a week (if planned), completely fill the aquarium with water (it should be separated for at least 3 x days), the filter with the water heater should work continuously without shutting down
(24 hours a day) and leave for 2 - 3 weeks to fully establish biological equilibrium. During this time, a colony of beneficial bacteria will settle on the filter material and in the soil, and you will be able to determine the aquarium community, i.e., fish.
In an aquarium with a capacity of less than 50 liters fit
1. Guppies alone or with specialties
2. Aquarium with harazinki - Neon, Cardinals, Minor, Ternetsii, catfish - Mottled, Antsistr, Golden, Gastromizon
If the aquarium is over 100 liters then you can
1. Barbs - kept away from other fish
2. Angelfish, Gourami, Sword-bearers, Black Moth - you can keep each view separately or together
4. Goldfish - one fish should have at least 10 - 15 liters without tail fin
It is necessary to transfer the fish to the aquarium slowly over a period of 3 to 4 hours for the night, pouring half a glass of water from your aquarium every 20-30 minutes into the bag with the fish brought.
It is desirable to feed the fish with high-quality feed, frozen bloodworm, daphnia, Golden feed with vegetable feed (like duckweed), dry food as an additive - adult fish 1 time per day, adolescents 2 times. 12 day a week full hunger strike (fasting day).


First you need to gather information ...
Believe the sellers in the zoo shop is not worth it ... believe me - 99% of them do not understand anything in fish and they have one goal - revenue ... therefore they will calmly advise you 20 gold and ten scalar in a beautiful 10L vase on the leg ("what?? glamorous after all?!?! ") and it is extremely difficult for a beginner to find from their amount the remaining 1%
Step one - decide on the type of fish ... for starters, choose 1-2 species and 1 type of catfish (from your own experience, especially if the aquarium is for a child - pay attention to the viviparous: guppies, molines, swordtails)
the second step - under the already selected type of fish we select the volume of the aquarium. carefully study the information about the volume of water for each species separately !! ! in many sources they give a formula of 1 l per 1 cm of the length of the body of a fish ... it is categorically not correct !!!! this formula is suitable only for the same live-bearers ...
The third step is to carefully study the information on the proper start of the system ... just pouring in the soil and pouring water is absolutely wrong ...
the fourth step - only after the information is read, the aquarium is up and running for 2-3 weeks without incident (for example, without cloudiness of water) only after that you can start buying fish ... do not rush to buy the whole flock at once ... break it 2-3 times ...
and do not rush to buy everything in one day ... I think if you stretch the child’s pleasure with the process of organizing the system - it will only be more interesting for him ... and as a result there will be less children's tears over the dead fish
there are a lot of aquarium portals ... it’s enough to type "an aquarium forum" in the search
as well as you can visit the aquarium community "Aquarium at Home" // here will always help and prompt


Do not buy an aquarium less than 50-70 liters. It is much easier to care for such volume, it is faster and better established biological balance. Better get an elongated rectangular aquarium. The soil is 1-2 cm thick, the plants are better alive - arrowhead, echinodorus, 2-3 bushes will be enough, they are unpretentious and grow well. Do not worry about the decor, a large number of spoils the look of the aquarium. A filter with aeration is required (I have Aquael, everyone is happy). Thermometer. Feed dry Tetra (I like). Get 1-2 somikov (pterihi, antsistrusy), fish, I would advise the Sword (they are bright and unpretentious), mollies (there are black, yellow, white), danios, cardinals. Once a week, the replacement of 20% of water (water from under the tap should be left for a day or two). Siphon clean the soil every 7-10 days. If necessary, you will have to clean the glass from the inside with a green sponge, but usually the teteter beautifully cope with this.
Good luck to you! If anything - write!

Residents for a small aquarium

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

Quite a lot of options)

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

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

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

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

Possible options for settling the FISH Aquarium:

1. Petushki:

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

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

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

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

2. Neons

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

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

Adult neon can reach a length of 4 cm.

3. Danio rerio:

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

There are several color forms of this fish.

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

4. Guppy:

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

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

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

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

Breeders are constantly working on new breeds of guppy.

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

5. Guppy Endler:

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

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

6. Corridor:

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

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

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

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

7. Corridor Pygmy:

View corridors, which is worth to say separately.

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

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

8. Cardinal:

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

9. Micro disassembly:

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

10. Norman Blue-Eye:

Симпатичные стайный рыбки, вырастающие до 3-4 см. Их глаза ярко светятся неоновым светом, что придает аквариуму своеобразную динамику и очарование.

Мирные стайные рыбки, температура воды 20-25 градусов. У меня живут и при более высокой температуре, очень активные и игривые.

И вот, мы рассмотрели рыбок, которые будут счастливы даже в небольшом аквариуме 10-30 литров.

Примерные варианты заселения:

10-ти литровый аквариум:


• 1 петушок;

• 5-7 гуппи;

• 5 неонов;

• 5-7 гуппи Эндлера;

• 10-13 микрорасбор;

• 5 синеглазок Нормана;

• 3-4 кардинала;

• 5-10 данио-рерио;

• 7 микрорасбор + 5 данио-рерио;

• 3 гуппи Эндлера + 5 данио-рерио;

• 3 неона + 3 гуппи.

20-liter aquarium:

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

• 1 cock + 3 corridors;

• 10-15 guppies or Endler's guppies;

• 15-20 Danio-rerio;

• 10-13 neons;

• 10-15 Norman blue-eyed;

• 7 cardinals;

• 20-30 microassembly;

• 7 pygmy corridors;

• 5 guppies + 5 neons;

• 15 Danio-rerio + 15 microassembly;

• 10 guppies + 3 corridors;

• 7 neons + 3 corridors.

30-liter aquarium:

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

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

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

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

Shrimps are unpretentious, cute and very interesting.

Aquarium SHRIMPS:

1. Cherry shrimp (cherry):

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

2. Amano shrimp (Japanese pond):

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

In captivity do not breed.

3. Shrimp Crystal:

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

4. Shrimp Cardinal:

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

5. Yellow shrimp:

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

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

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

The calculation is approximately as follows:

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

Shellfish in an aquarium:

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

1. Helena:

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

2. Neretina:

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

3. Ampularia:

The most favorite snail, very often found in aquariums.

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


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

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

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

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

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

3. The filter should work around the clock !.

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

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

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

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

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

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


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

Successes to all who decided to start an aquarium!

Next time I will try to tell you something else interesting from the world of aquarism)
