My first aquarium: whom to start

If someone wants to buy aquarium fish for the first time, he probably thinks that the easiest way is to keep small fish in a small round aquarium. However, it seems so at first glance. From the experience of experienced aquarists - it is easier to care for big fish and a big aquarium. But this is not the only secret. Whom to get?

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

Before the purchase

Aquarium fish after purchase in the pet store in the purchase package will live no longer than 5 days. Therefore, you need to take care of their place of residence in advance. That is, for two weeks to establish an aquarium, provide it with soil, water, filter, aeration. In one aquarium, you can keep fish that are close in temperament, behavior, needs and habitat, but for a start it is better to opt for the fish of the same species.

Buy fish should be in accordance with the size of the aquarium. For most species of aquarium fish, their number should be calculated as follows: for 1 liter of water in the aquarium, 1 cm of a fish body. For some species of fish free space requires much more. And individual individuals cost less water. No need to get involved in the number of fish and recruit a lot at once. It is better to aim to buy them no more than 4-5 pieces.

Before you start buying fish, you need to study the information about their appearance, behavior, habitat and natural care for them. These signs will be useful to determine the health of the fish. For example, when purchasing it is necessary to carefully monitor that the pet's body does not have pustules, suspicious spots. Observe the behavior of the fish in the aquarium to eliminate its lethargy and poor health. Inspect on the subject of integrity of the fins, tail, eyes. Inspect that the fish did not look like a skeleton, covered with leather, because this will be difficult to leave.

Selection of aquarium fish

The best aquarium for beginners is a roomy aquarium of approximately 100 liters and more. It will fit big, beautiful, mobile fish - cichlids. This is the most favorite type of many lovers of aquarium fish. Because this animal is very unpretentious to changes in water temperature, rarely gets sick, eats a varied diet. This family of fish is ideal for an inexperienced aquarist. In addition, the main goal - admiring the delightful color of fish and their smooth movement - will be achieved.
If the buyer of the fish has set himself the goal to buy various beautiful small fish caressing the eyes, then you can ask the seller which fish at least do not eat each other exactly and get along well with each other. And will they be able to live with the algae in the aquarium?
If the aquarium is not so large, for example, 25 l., Then the beginner can choose such unpretentious and at the same time beautiful fish, like mollienesias, guppies, swordtails. Also very popular with inexperienced aquarists are various types of zebrafish and barbs. They easily breed, differ in their peace-loving disposition, it is easy to care for them. For the first aquarium, some fish from the group of Kharacin fish will do. For example, neons that shine with neon color of different shades. Also minor, flashlights and erythrositis.

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. Once a week, arrange fasting days for fish. Add food to 4-6 grains, which pet is swallowed by force. What is not eaten, you need to remove the gauze net.

Let's for fish that live in a small 10-20-liter nursery as much feed as they eat in 2-6 minutes. Flakes, live food, sinking granules fit. They sink slowly and do not pollute the environment. If you live on bottom catfish, they will eat everything on their own. Fish can be fed to their usual high-grade food, without disturbing the diet. It is important to clean everything in time.

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, erythrozone, 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.

In the world, of course, even more wonderful fish, but I would like to list those that you can buy, and at the same time the content was affordable.

flower horn thai silk


Fish-pessimist, say any psychologist, just looking at the expression on her face. After that, it will be cursed by the Chinese, as in the east, owning such a fish is very feng shui. It is believed that she brings money and happiness to the house. It is not known how it brings it, but the fact that arabana with a rare coloration takes them away a lot is a fact. In nature, lives in the Amazon, as well as lived in the Jurassic period. Everything is quietly bursting, including birds who are chasing the birds, who have decided to sit on the lower branches of the trees.

Kalamoicht Calabar

Or snake fish, you catch one when fishing, and at the same time you catch a heart attack. But, for people it is completely safe, that you can not say about small fish. Adapted to life in Africa and can afford to go for a walk in another reservoir, if she is tired of this, because she can breathe atmospheric oxygen. The same likes to do in the aquarium, so that the cracks can not be left.

Apteronotus white-eyed

Or what is his name still - a black knife. And what, it looks like ... But who sees him for the first time finds it difficult to say, but what exactly does he see? He looks like a fish less than a knife. He lives in Amazon, and the locals are so impressed with him that they believe that deceased relatives move into these fish. I would say the dead mother-in-law ...
In an aquarium it looks interesting, it swims interestingly, it is interesting to eat small neighbors.

Butterfly fish

Patondon or butterfly fish, another survivor who survived dinosaurs, and it may well survive us. He lives in Africa (well, everything strange lives there ...), and he is so keen on flying over water, that something flying under it does not exist for her. For this, she only looks up and even jumps out of a particularly tasty fly out of the water. If you decide to buy it, then train the love of flies and beetles, you will need to grow them.

Dwarf tetraodon

Fish optimist, just look at the eternal smirk and try to look into the shifty eyes. This is a collection of interesting things in one small, round body of a dwarf tetradon. Do you know puffer fish? Here which the Japanese cook and eat with the risk of poisoning? So, these are close relatives. And tetradons can swell up to the state of a ball in order to make the predator breakfast less enjoyable. They also swim like small airships, ignoring the age-old abilities of other fish.

In the aquarium, he cheerfully cuts off the fins to other fish, small swallows without chewing. And yes, if you decide to contain either a file, buy it, or a snail bag. The tetradon is constantly growing teeth, and he needs to either file them or give something hard to bite, such as snails.

Flower horn

Color horn or tsvetorog ... or how to translate it, in general, his excellency flower horn? More recently, no one knew such fish until someone in Taiwan crossed something with something by mixing several cichlids. Who and with what is still a mystery, but it turned out such a handsome man, from whom in the East everyone goes crazy. And what, grows big, eats everything, fights with everyone. Macho Fish And yes, the bump on the head is its peculiarity, there are no brains, only fat.

Gipantsistrus Zebra L046

Yes, yes, personal number, everything is serious. Numbered catfish, which lives in Brazil and has become so actively exported from Brazil, that it is prohibited for export. But, the Russian craftsman cannot stop such nonsense, and now the fry have appeared on sale. No theft, breeding!

In addition to coloring also a sucker instead of a mouth. Gipantsistrus but in spite of the suction cup, prefers live food, while like other catfishes they feed off by scraping every bjaku from the stones.


Oh, this is not one fish, it is a lot of fish of different sizes and colors. But, one snakehead unites, they are somewhat similar to snakes, they eat all living things, and some even have quite real fangs. You can look at the video that these cute fish can do with other predators. And yes, they also breathe air. In the aquarium, some may live with other fish, some will consider other fish as tasty food.

Golden cobra

Elephant fish

Again, living in Africa, and for which she was called an elephant, you can understand, just look at the photo. In nature, an elephant fish clings to the bottom, where its trunk finds all that is tasty in silt. And yet, it creates a rather strong electric field, with the help of which it is oriented in space, searches for food and communicates with partners. In the conditions of the aquarium refuses to multiply, and behaves rather shyly, hiding in dark corners.


When you see this fish for the first time, you will not immediately understand that this is a fish .... Something so flattened with eyes and tail resembles a flounder, but just not a flounder, but a beforta. In fact, it is a small fish that lives in nature in fast waters, with a strong current. This body shape, like a sucker, help her not to fall off the stones. He lives successfully in an aquarium, although special conditions are needed for maintenance.

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.

(last 2 photos - females)

5. Guppy Endler:

In fact, the same guppy. Но гуппи Эндлера - дикая форма, над которой не успели потрудиться селекционеры. Такие рыбки водятся в Венесуэле. легко скрещиваются с простыми гуппи и производят очень даже симпатичных гибридов)

Гуппи Эндлера мельче, чем обычные гуппи: самцы достигают длины 2-3 см. Отлично смотрятся в маленьких аквариумах с темным фоном!

6. Коридорас:

Так называемый, "крапчатый сомик". На самом деле, коридорасов очень много видов, просто крапчатый - самый известный из них.

Коридорасы любят компанию, покупайте сразу 3-5 особей. 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:

Cute schooling fish that grow up to 3-4 cm. Their eyes glow brightly with neon light, which gives the aquarium a kind of dynamics and charm.

Peaceful schooling fish, water temperature 20-25 degrees. I live at a higher temperature, very active and playful.

And so, we looked at fish that would be happy even in a small aquarium of 10-30 liters.

Approximate settlement options:

10 liter aquarium:


• 1 cockerel;

• 5-7 guppies;

• 5 neons;

• 5-7 guppies Endler;

• 10-13 microassembly;

• 5 Norman blue-eyed;

• 3-4 cardinal;

• 5-10 Danio-rerio;

• 7 micro-sampling + 5 danio-rerio;

• 3 Endler guppies + 5 danios-rerio;

• 3 neons + 3 guppies.

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 start spoiling 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)

It was inspired here just from the last questions - who should be started in an aquarium, except for rodents and fish?

Mr. Tetra

For Achatina 100 liters somehow fatty. They have a comfortable life for the eyes enough 10 liters per person. And if there are more than one of them - they will begin to multiply with terrible force - 100-400 eggs almost every month.
And since the animal is completely trouble-free, though Malts is amorphous - it is interesting only when it eats or is bathed. Although fascinating in its slowness.
Soil (aquarium) is not suitable for them, we need land with some kind of a thinner like coconut substrate (to keep moisture and not smearing along the walls). And the slime there is not so much.
And yes, by the way, it is very well suited as the first animal for a child - the care is not complicated and you can check for responsibility.
And one more plus - to find them is not such a problem, many are giving away for free

! Lazy!

I myself thought about Achatina, yesterday a girl on VK suggested,
the game seems to be trouble-free, and in some sense amusing,
I thought to take a sonulka, I must master such simple care
I used to have a snake or a spider, he asked, well, or a cockroach, but this is absolutely for me ((

I want to make fish at home, what tools are needed for this, except for the aquarium?


Compressor. Light they need. Water heater Filter so that the water does not quickly become turbid. Food. Sponge Banachka for fish. Net. All sorts of pebbles and algae with shells. And of course the fish! =)) I myself have an aquarium.

Joseph Famelia

the filter is the same as a water aerator, and the water in the aquarium does not change, but topping up the settled for at least 3 days, but if it quickly overgrows and the water becomes cloudy, then add a little but boiled water.
If the fish are not warm-loving and the aquarium is at the window and well lit. so you have to shade. you can do without lighting and heater, it depends on the fish and plants.

A dog ... a cat ... and who else could have been brought home? ... but without much hassle and not from exotic things of course


Any animals need care. What about the turtle as he wrote in! Vic is not so simple, she needs a terrarium with appropriate conditions close to the natural habitat, plus if it is not correctly translated into hibernation, it can die in winter. But the rats and guinea pigs are really unpretentious (the minus in rats is the average life expectancy of about 3 years). The first time an aquarium brings anxiety, well, if a microclimate is established, then in the future a minimum of worries (of course, provided that the equipment is properly selected.)
In addition to the cat, I personally have three turtles living at home and there are two small aquariums for 100 and 60 liters :) after they buried three rats (they died of old age), we no longer start, the sediment is not good every time from the loss of a pet.

Anastasia Petersburg

Without the hassle ... But even the cactus (!) Must sometimes be watered.
Get a ceramic turtle - do not eat, not cf. * t, do not crawl under your feet.
P.S. I like big snails, Ahatins ... But they need to be fed, kept in an aquarium in the ground and warm, and sometimes walking.

In! Vic

Without the hassle, only cockroaches, even if they are not fed, will survive ...
But seriously, the land turtle sleeps all winter, eats all summer ... not run away, that is, even if you let out “run” you don’t need to watch out for it and they live long and do not take much space. The most budget option pet.

Inna PPPrima

lab rats! It is better to start one. They are such contact! ! If with the mind, then you can accustom to everything. The first rat in our house went everywhere, and to eat and went to the cage. and slept in a cage at night. After brought two males. One (it was true) was a super walk in the apartment, smelled with a dog, came in the evenings to the kitchen to our voices. The second (still there) is wildly, but still children play.
