When you can run the fish in a new aquarium


How to run the aquarium for the first time?

Resolved, we will have an aquarium! He has already been selected and purchased, the equipment is waiting for the coolest next to him in beautiful boxes, the bottom is already filled with bright red brilliant, terribly spectacular soil, and there is a ceramic crocodile on it that will blow bubbles. Now we pour water and, while she stands up for an hour or two, let's go to the pet shop and buy the best fish there - those with long fins, and other yellow ones with red dots (whatever they are called? However, it doesn't matter, the main thing is beautiful) ...

Stop! No matter how commendable is the desire to join the fascinating world of aquarism, this process should not be forced, otherwise the first experience may be so deplorable that one does not want to continue. Let's tolerate a little more and see what should happen to a glass jar full of water in order for it to become an aquarium.

Aquarium is a balanced biological system in which many living organisms coexist. These are not only fish and plants planted by the host, but also self-inhabited small invertebrates, protozoa, algae, bacteria. And in order for the aquarium to be beautiful and comfortable for life, the whole system must be in balance. Substances entering it from the outside should be processed without deteriorating the vital indicators of water and not causing death or, on the contrary, uncontrolled outbreak of the number of any inhabitants, and then removed from the system during water changes and cleaning the aquarium.

What you need to do before launch?

Even before the launch procedure, it is necessary to solve a number of critical issues and take some necessary steps:

  1. Decide what kind of fish or aquatic animals you want to have. Find out what conditions they need. Be sure to find out if they are compatible with each other!
  2. Depending on the decisions on the first item, choose the volume and model of the aquarium, as well as a list of necessary equipment and design items. Based on the species and number of future inhabitants, decide whether you need a heater with a thermostat, for example, how powerful the filter should be, whether an additional compressor is needed, how to decorate an aquarium: stones or driftwood, which plants to plant, and so on.
  3. Choose a place for the aquarium - not in the draft and not in the sun. It is also important that access to the aquarium was convenient, and there were a sufficient number of outlets nearby.
  4. Buy and install an aquarium (necessarily on a flat surface, so that its edges do not hang from the shelf or pedestal even per centimeter). Pre-aquarium washed without the use of chemical detergents.
  5. Place the equipment in the aquarium: filter, compressor, heater and thermometer, lighting. Fill the soil with a layer of 3-4 cm. Depending on the type of soil and its source of origin, it may be necessary to pre-heat it, boil it or rinse it. The same applies to stones and snags.

Now the aquarium is ready to fill up with water and start running. But before we give a step-by-step start-up instruction, let’s try to figure out what this notorious launch is for and what the running aquarium is different from the one that is not running.

Quite a bit of theory

As we already wrote above, the aquarium is an open-loop system, where various substances come outside. This is mainly fish food, which the fish eat, while releasing waste. In chemical terms, ammonia is the most significant and toxic part of this waste; even in low concentrations, it can cause poisoning and subsequent death of fish and other aquatic animals. However, in nature there are bacteria (they are called nitrifying) that consume ammonia, oxidizing it to nitrite. Nitrite for fish is not much better than ammonia, but there are other types of nitrifying bacteria, which in turn bind them, turning them into relatively harmless nitrates.

This whole system of bacterial colonies, which makes water with nitrates from poisonous ammonia water, quite suitable for fish, is called a biofilter. Since the efficiency of the biofilter directly depends on the number of its constituent bacteria in the aquarium (it is clear that two or three microscopic nitrosomonas cannot convert ammonia, selected by a dozen large goldfish, into safe compounds), these bacteria must be allowed to multiply to the desired number. For this they need three things:

  • nutrition (ammonia and nitrite);
  • substrate (surface to which they can attach);
  • and for some time, as bacteria multiply rapidly, but still not lightning.
And now, finally, we will formulate what the launch of an aquarium is: this is a set of measures that allows the biological filter to mature and begin to work fully. Or, in other words, cultivation in the aquarium of such a number of nitrifying organisms, which will be sufficient for the processing of ammonia and nitrite, allocated by all the inhabitants of this aquarium.

Run (instructions for beginners)

So, we will analyze the points, how to run the aquarium correctly:

  1. The run starts with water pouring. Water must be poured plumbing, pre-defend it is not necessary. After pouring water turn on the filter with aeration. If the filter does not have an aerator, then the compressor must additionally work, since nitrifying bacteria require a lot of oxygen and a heater (set at 24-25 °). In this form, with the lights off, the aquarium is left for 5-7 days. All these days they spend only monitoring the operation of the equipment: check whether oxygen is supplied, measure the temperature of the water.
  2. After 5-7 days, unpretentious fast-growing plants are planted, after which they turn on the lighting for 4-5 hours a day.
  3. After 1-2 days you can start the first aquarium animals. This may be small unpretentious fish (viviparous or, for example, danios), but it is better to use snail ampoules or hymeno-viruses that are more resistant to water quality. There should be few animals. Feed them once a day in very small portions. It is necessary to constantly monitor their behavior and appetite. Ampulyaria, for example, are excellent indicators of water quality: in clean, good water, they rush around the aquarium at cruising speed, straightening antennae and looking for food. At this stage, the light is turned on for the whole day (8--12 hours), you can add special bacterial cultures to the aquarium to start (they are available from different companies, for example Sera Nitrivek).
  4. After a week, the remaining plants are planted and begin in parts (at intervals of 1-2 days) to launch the main fish population. For each released party you need to carefully monitor, feed moderately.

That is, in fact, all science. True, nothing complicated?

Of course, the equilibrium in the aquarium is still unstable, and some time after the launch such unpleasant phenomena can occur, such as outbreaks of diatoms. But if the launch was carried out correctly, these problems are usually not catastrophic, do not lead to a massive freezing of fish and are solved in working order. To combat these diatomies, for example, a small charming catfish otozinclus is successfully used.

How to facilitate the process of starting the aquarium?

Above, we wrote that for the reproduction of beneficial bacteria need nutrition and substrate. And, of course, the initial number of the bacterial colony matters. Thus, in order to accelerate the maturation of the biofilter and, accordingly, the launch of the aquarium, you can immediately add a significant amount of bacteria to the artificial reservoir and prepare a large area substrate for them (there is enough nutrition for the bacteria in the starting aquarium).

Bacteria are introduced with the help of industrial starter culture (we also mentioned about them above) or with water, soil, filter filler from the existing, safe aquarium. To ensure a sufficient area of ​​the substrate for bacteria, it is recommended to use filters with fillers made of porous ceramics or filters of considerable volume with other fillers, plant plants with narrow, feathery leaves, and use fine gravel of even size as the soil. All these surfaces will inhabit nitrifying bacteria.

Startup control of the aquarium greatly facilitates the use of tests for aquarium water for ammonia and nitrite. These tests are produced by different manufacturers and are not uncommon in pet stores. With their help, you can track the level of these toxic compounds in the water and adjust the population of fish in the running aquarium.

As you can see, the correct launch of the aquarium takes not so much time - it is quite possible to suffer two or three weeks. It does not require a colossal amount of strength and special academic knowledge. But it helps to avoid many problems in the future, preserves the life and health of the fish, and therefore, the nerves and good mood to their owner.

Running aquarium with fish

Launching a new aquarium is a complex process that requires careful preparation. In order to properly organize the launch of a new aquarium for fish, you need to prepare the aquarium itself, plants for it, decorations, a filtration system, a backlight, and a compressor with a spray. After purchasing all the equipment, it is installed, then water is poured. But that is not all. In the aquarium should be formed favorable biological environment of beneficial bacteria.

First preparations

Choose the size of the aquarium depending on what types of plants and fish you are preparing to launch. For large fish, it is better to prepare a spacious tank of 300-500 liters or more, for a flock of small fish - up to 250 liters. For one fish, a capacity of 50-60 liters is enough, but in the way of life, not all fish are lonely, so consider this feature. In a close aquarium, it is difficult to maintain a biological balance, and if you plan to buy new fish, its volume will not be enough.

See how to choose an aquarium.

Before starting a new aquarium, you need to wash it properly. Do not use soap or other detergents. Baking soda is not toxic; it washes away all germs and alkali. Rinse the tank walls with running water 4 times. Frame aquariums can be left under water for several days, during which time toxic substances will be washed off. The water in which he was located must be drained. Check if the walls of the aquarium are leaking.

Put a clean tank in a specially prepared place. You can not put it on the window sill, in places of draft and direct sunlight. Bright lighting will trigger algae reproduction and water bloom. The place for the aquarium should be permanent. Try to put it where there will be less noise, evaporation from the room battery.

Choose a table or cabinet for an aquarium of such height and surface area that could support the weight of the structure. The surface must be smooth and clean. The water pressure at the bottom of the tank is high and the bottom may crack on an uneven surface. You can use a rubber mat as a lining.

Water and scenery in an aquarium

Now you need to prepare equipment for the aquarium. Determine where it is better to put the compressor with air ducts, how to connect the lighting and the water heater. Consider where you can leave the net for transportation, the siphon with the hose, the scraper and the water collection tank. If you have thought about where you will install the equipment, you can lay the soil substrate.

Decide in advance on the type of soil - it can be gravel, pebbles or sand. Soil needs to be processed, wash out all suspended particles and remnants of large fragments. Some types of soil need to be treated with boiling water, in any case detergent. After preparing the ground, the next day you can plant unpretentious aquarium plants in it, such as valisneria, anubias, hornolistnik, elodeya and others.

Watch the video with recommendations for choosing aquarium soil.

Next you need to pour prepared water into the tank. You can not pour the water recruited from the tap, it is harmful and toxic. Let her stand for 3-4 days to get chlorine fumes out of it. It will heat to room temperature. Take measurements of water parameters using indicators. When all indicators meet the standards, you can pour water.

Later, place stones, rocks, caves, earthenware pots and treated wood snags in the tank. Attach the filtration system (external or internal filter), aerator, heating system, thermometer. If the equipment manual allows, you can install mechanisms after the water inlet. For a decorative aquascape, all parts must be as hidden as possible. With the help of large stones, driftwood and bushes of plants you can cover the installation.

After all the preparations, the water can be poured in little by little, so that the soil does not become washed out and the water does not become cloudy. On a layer of soil you can put a ceramic plate, and pour water directly on it. Then turn on all devices and check their performance. Inspect the tank for damage.

Running fish

To properly prepare the aquarium to run the fish, you need to wait a few days, when it will establish biological balance. After 2 days in the new aquarium, the water becomes turbid - this means that ciliates and useful bacteria actively proliferate in it. This is a signal that the preparation of the aquarium was successful. After 2-3 days the water will be clean, it may turn yellow. If you add water from the old aquarium to the reservoir, the beneficial microorganisms will quickly establish biological balance. You can buy a special leaven with good bacteria in the pet store, and add it in the required proportions to the water.

After 7-8 days after adding water to the aquarium, you can run the first hardy and undemanding fish. It is correct to start schooling fish at once on 5-6 individuals and more, singles or paired fish - only in pairs. Viviparous species of fish and barbs will help the aquatic environment to quickly come into balance.

To prepare the fish for launching into the tank, they need to be placed in a portable water bag from their previous aquarium. Gradually lower the fish in the bag into the new water so that they get used to its temperature. After 20-30 minutes, the new water will become familiar to them. To avoid stress, anti-stress drugs such as Tetra Easybalance or Ptero Aqua Antistress can be added to the tank.

Run the aquarium from scratch. Preparation and proper launch of a new aquarium: step by step instructions

The launch of a new aquarium is carried out after all the decorations, soil and plants have been purchased. This process, contrary to general delusion, does not begin with the purchase of fish and involves carrying out five preparatory stages. The lion's share of success depends on the purchase of all the necessary equipment. It must be of high quality and resistant to wear, as some systems will operate around the clock.

Selection rules

Starting the aquarium from scratch should start with the choice of the tank itself. If the aquarist is a beginner, it is preferable to choose medium-sized models, the volume of which varies from 80 to 200 liters. Such a step makes it easy to maintain biological balance in comparison with small containers. The step-by-step start-up of the aquarium, described below, will help to avoid problems.


All filters are divided into two large categories - external and internal. Beginners who launch the aquarium from scratch are encouraged to acquire good internal ones, which will also save. Manufacturers indicate how much water filter is designed, so it is almost impossible to make a mistake. However, experts recommend choosing such equipment with a small margin.

Heater with thermostat

This device maintains a comfortable temperature for all participants in the system. Manufacturers also indicate the recommended volume on the package. When starting the aquarium from scratch, the choice is usually not difficult.


A special beam spectrum is an important condition for the full existence of aquatic plants. They grow well under special-purpose lamps with intense lighting. On average, one liter of water requires a power of 0.6 V, that is, at least 60 V per one hundred liters, and all 90 is better.

When there is a launch of the aquarium from scratch, it should be noted that the daylight should be the same. Automation perfectly copes with this (special timers).


Experienced aquarists recommend to give preference to a special film of black or dark blue, you can also pull on the tablet, commensurate with the parameters of the rear window, the fabric of the desired shade. It is this background that will perfectly emphasize the beauty. Split glossy photographic backgrounds are not the best choice; launching an aquarium with plants can be ruined.

Carbon dioxide saturation system

In the daytime, carbon dioxide is necessary for all the vegetation of the system to grow, especially if there are a lot of fish there. It is recommended to pay close attention to CO2 parameters. Устанавливать систему насыщения рекомендовано после стабилизации биологического равновесия, в том числе когда идёт запуск аквариума с растениями.


Изделие должно быть прочным. Вес столитрового аквариума составляет 140 кг. Можно приобрести специальную тумбу или приспособить уже имеющуюся мебель. The aquarium, the photo of which is presented below, is installed on the cabinet correctly.

Run Stage One: Verification

First of all, it is necessary to determine if the tank is leaking. To do this, it is placed in the bath, preferably on a flat surface. The aquarium is filled with running water up to half the volume, after a day it is completely filled. Such a test is carried out in any capacity vessels - only this way it can be understood if the glass will burst and the product will carry the first launch. After checking the water is drained, it is better to wash the tank. The aquarium is installed on the cabinet.

Run Stage Two: Ground

As a rule, the soil is represented by gravel of the fine fraction, which is suitable for most plants. Before you put it in the aquarium, it is better to conduct a heat treatment, for example, boiling. After that, most of the soil is mixed with the starting fertilizer.

The base is laid out neatly on the bottom in an even layer, the height of which should not be less than 4 cm. In some cases it is advisable to arrange an uneven layer: small at the front glass, gradually rising to the rear wall. It is better to immediately plan the places where the plants will be located. At this stage, it is important to do everything correctly to avoid further refinements. When choosing a place where plantings will be located, it is better to focus on lighting and remoteness from heating appliances. Artificial and natural decorations are placed on the ground.

Run Stage Three: Installation of Equipment

The heater-thermostat, pump with filter are brought to the aquarium. Technique remains unconnected.

Run Stage Four: Planting Plants

When placing living vegetation should be guided by these recommendations:

  • Near the rear wall are large plantations.
  • In the middle part, it is customary to plant smaller specimens.
  • In the foreground - the smallest, they will be closest to the observer.

Beginners should choose inexpensive, viable plants, such as valisneria or hornpole. Such instances help to quickly establish a balance, after which they can be replaced. In addition, a special bacterial starter can be used to accelerate the stabilization of the biological balance. It is introduced into the water according to the instructions. Plants when planting should be constantly sprayed with a spray.

Run Stage Five: Gulf of Water and Connection

Water can be used the most simple - plumbing. It must be allowed to stand in order for the chlorine to completely evaporate. If you do not want to wait, you can buy bottled drinking water.

To prevent erosion of the soil, a saucer is placed on its bottom. The flow of incoming water should fall on him. Aquarium is full. Then you can turn on the equipment. It is necessary to immediately check how the filters function, heating, what temperature level is established in the system. The filter should work all the time, it can not be disabled. After a few weeks, the inside of the device creates its own bacterial environment, which becomes a biological filter. If you turn it off, the bacteria will quickly die without oxygen and fresh water. Their place will immediately be replaced by anaerobic microorganisms that produce hydrogen sulphide and methane - from them the whole system will cease to function.

The final check should take place seven days after launch. In the first days of work, the water in the aquarium will become muddy, as part of the plants will die off, and the bacteria will begin to multiply rapidly. The activity of microorganisms normalizes this process over time, and it will be possible to talk about the stabilization of the internal biosystem. Only then the tank is ready to receive fish. It will take about a month to complete the formation of an environment where every resident will feel well. One fish should be about 10 liters of water.

How to run the fish

A week after the start of the launch, it is desirable to increase the lighting time of the aquarium to 12 hours. At this time, you can run unpretentious species of fish in an amount not exceeding one third of the allowable for such a population size. It is important that with the proper launch of the fish at this time should remain hungry - it is absolutely harmless for them. Feeding can disrupt the nitrogen cycle, resulting in the need to restart. Food fish will be able to get after four days.

A few days later, the aquarium may be populated by half of the population. During this period, you can run more capricious fish. After seven days you can run all the fish.

If the house has soft water, you should choose those inhabitants who prefer this pH level, and vice versa. The aquarium, the photo of which is presented below, is launched absolutely correctly and delights with its beauty.

Marine type

Starting a new aquarium may be difficult if it is of a marine type. All stages are similar to the previous ones, but water requires special preparation. It must be treated with reverse osmosis, and then settled for three days. After that, the salt concentration is brought to the required level.

When the optimum salt balance, density and temperature of water are reached, you can fill up the ground: sand or coral chips. Further, in the system, you can place live stones, plant corals, decorate the bottom with shells. A week later, you should check the performance of nitrite and ammonium in water. A month after the water preparation, it is possible to launch the fish in the marine aquarium.

Rules successful aquarist

  • you need to purchase only healthy fish in trusted stores;
  • fish can not be overfed;
  • it is better to check regularly how all systems work;
  • the fish must have sufficient living space;
  • fish living in the same system must be compatible;
  • nitrogen cycle support;
  • periodic cleaning of the filter;
  • even a beginner needs to know what is water hardness, pH, buffer capacity;
  • a regular partial replacement of water is necessary, even if the first launch of the aquarium occurred less than two weeks ago.

Instead of conclusion

The rapid launch of the aquarium in 99% of cases does not lead to the desired results, it is often necessary to repeat the cycle of preparation. A beginner aquarist must be patient in order for the system to stabilize and fully function.

The question of how to prepare an aquarium for launching has become very relevant lately. Many families want to get beautiful fish that will swim surrounded by vegetation. However, the maintenance of the system requires a certain amount of effort from the owner, which is better to take into account at the stage of making the decision to install an aquarium. In addition, we must not forget about the need for fixed costs for the maintenance of the system, including the purchase of fish food, replacement filters, etc.

Top 10 fish to start with

Deciding what kind of fish to start first in your tank can be sudden, and can be thought out. Unfortunately, novice aquarists are often guided by the very first impulse, completely without understanding the fish. And then, instead of joy and pleasure, they get a headache and problems. You need to choose the fish wisely, because their life and your comfort depend on your choice. Before you go to the store or to the market, study all the available information about the fish that you liked.

What kind of fish is not worth buying for beginners, we have considered here. And the top 10 unusual fish here.

And in order to make it easier for you to navigate, we have compiled a list of the best aquarium fish for beginners and briefly described them. All of them are distinguished by unpretentiousness, tolerance to conditions in an aquarium, peaceful nature, livableness and modest size. We hope that it will help make your choice easier!



A classic for any newcomer to aquarism is guppies. They are very unpretentious, livable, and just get divorced. It is very easy to distinguish males from females, males have a big tail, they are much brighter, and their anal fin is elongated. The females are larger, fuller and the anal fin is shorter, and most importantly - they are gray, only the tail fin can be colored. They are viviparous, which means - the fry immediately swim and are adapted to life. At one time, the female guppy can sweep from 10 to 60 fry. But if you leave the fry in the general aquarium, it will be eaten quickly, you need to catch the fry in a separate container. To breed them is very simple, it is enough to keep together the males and females.

Guppies eat all kinds of feed, can grow well on branded feeds - flakes, granules, etc. It is worth noting that beginners are not recommended to start pedigree forms of guppies, because of the long mixing of blood, they, on the contrary, have become capricious and difficult to maintain.

Males of guppies of different breeds

There is also a species of Endler's guppy. The differences between endlers are much smaller in themselves, the males are not veiled, they are much more agile, the fry are less infected, but the fry themselves are larger and breed more often.

Sword-bearers / Molly / Pocilia /

We will unite them in one group (swordtails / mollies / squares /), since they are very similar in behavior and content, although outwardly they are very different. Just like guppies, they are viviparous. And that means there will be no problems with the fry, he immediately swims, eats, hides.

They are very simply divorced, the principle is the same as that of a guppy - just keep the males and females together. They are very bright and mobile fish, you will not need to look for them to consider, on the contrary, they will always beg for food from you. They tolerate various conditions in the aquarium and forgive mistakes that beginners often make. They eat all kinds of live, artificial, frozen feed. In general, they are similar to guppies in content, but outwardly larger, have a variety of color and body shape. As a precaution - do not buy a lot of male Swordtails in one aquarium, they can fight!

Petilia and mollies during feeding

Danio rerio

Danio rerio is a small (up to 5-6 cm), elegant fish. For its small size, peaceful disposition and unpretentiousness, it has earned great popularity in aquarium.

Since this is a schooling fish, it is better to keep at least 5-6 individuals. The aquarium can be planted with plants, but it is important that the danios have free space for swimming near the surface, as this is a very mobile fish. If you are going to have a veil form, do not plant them with fish that may tear off fins, for example, with a Sumatran barbus. The aquarium should be closed, as danios can jump out of the water.

Omnivorous, they eat any kind of feed - branded, live, frozen. It is better to feed them with flakes, as they pick up food from the surface of the water and they don’t collect them for a long time without sinking. It is very easy to breed danios, for once the female lays from 200 to 500 eggs.

Danio rerio


This is a very small (2.5-3 cm) and very unpretentious fish. However, it is brightly colored, just divorced and completely non-aggressive, even the cardinals do not touch their fry. They tolerate cold water, some even keep them in the summer in a pond in the yard. They love to move in the middle layers, and also like to gather in flocks. You need to keep them in small flocks, from 6 pieces. Although it is possible and large, with its modest size, the cardinals do not require large aquariums. With good content can live up to 3 years.


These are small, mobile, beautiful and pack catfish. There are many different types of corridors, but the most popular are speckled catfish and golden catfish. All of them are similar in their behavior - living at the bottom, they are constantly looking for remnants of food, thereby cleaning the aquarium. They are very mobile, while remaining quite small, and carry the widest range of conditions.

Any type of feed is suitable for feeding, but it is important to ensure that the feed falls to the bottom, and catfish do not stay hungry while other fish stuff their bellies. It is best to feed the corridors with special food for catfish, they quickly sink, and falling to the bottom do not fall apart. It is better to keep the corridors in the flock, they like to live surrounded by relatives, and it is very interesting to watch them in the flock.

Speckled catfish

Wedge specks

Very beautiful and very small fish, which is perfect in the neighbors for all of the above fish. Grow up to 5 cm and very peaceful. Beautiful coloring, on which a black spot stands out (for which it got its name), its small size and peaceful disposition made it very popular. It is better to keep the cuneiform pack in a flock, and there should be enough free space in the aquarium for swimming. The flock rasbor keeps together and very much decorates any aquarium. You can feed a variety of feeds, it is only important not to give large ones, as it simply cannot swallow them.

Flock rasbor


This is one of the most unusual fish that even an inexperienced aquarist can see.

Related to the vines, it resembles a small snake. But it is completely harmless, and quite durable. Acantoftalmus often hides during the day, and in order for him to feel comfortable he needs shelter and soft soil in which he likes to dig. In soft ground, he is able to find and dig a buried moth, not to mention other feed.

If there is sand in the aquarium, it will be buried in it with pleasure. So it helps to keep the aquarium clean, eating everything that falls to the bottom. You can feed him with any sinking feed, but additionally pour feed for catfish, better at night. Can escape from the aquarium, you need to cover it. The readers said that in the sand they could dig in stones, but I had never met with such a thing, mine definitely did not undermine anything.



Fishes belong to the same genus - labyrinth. These fish live in water that is poor in oxygen and adapted to this by learning to breathe oxygen from the surface. You will see how they rise to it, to take another breath of air. Small, peaceful, males are very brightly colored, and their ventral fins have turned into long processes. You can feed any feed, including floating. Only give the moth with care and a little, it is poorly digested.

Already after the publication of the article, my readers corrected. The essence - liliaus can be difficult for beginners (he is just a little flaky and jealous of females). I agree, and add that there is another wonderful fish of the same kind - gourami. There are many types, but for beginners a good choice would be marble gourami. Very hardy, peaceful, of unusual shape and color. It is generally similar to lyalius, but larger and less demanding. So you can stop at this gorgeous fish, and start up a little later.

Cherry Barbus

Peaceful, small fish, the males of which have a very bright color, for which they got their name. This is a schooling fish, so to keep a cherry barb is better from 5 pieces. But you will notice that he keeps loosely, gathering in a flock only in case of fright. The size of the cherry barb is small, the color of the males is bright red and very noticeable, the requirements for the content are low. This is a good fish to mention on our list.

A pair of cherry barbs


Perhaps this is the largest fish from the list, grows about 15 cm, if the aquarium allows. But he earned his popularity for his unusual appearance, for clearing the aquarium and his stamina. Antsistrus is a catfish, but catfish is unusual, it lives in nature due to the fact that it eats algae and fouling.


And his mouth turned into a suction cup, with which he scrapes it all. In the aquarium, he is a cleaner walls and decor. The males have unusual growths on the head, making it very memorable. Peaceful, but with other males can arrange fights. For him, it is important vegetable food, you need to feed special pills.


Of course, this is an incomplete list, and after thinking it can be increased significantly. But the task was to acquaint beginner aquarists.

Beginners, I recommend first to learn all about the fish that you liked, and choose first of all hardy, easy-care, and peaceful fish that get along well with others in the general aquarium.
And experienced ask for your thoughts about the fish, which they consider simple, in the comments below. I am sure many beginners will thank you for it.

How to run the aquarium?

Elena Gabrielyan

Step-by-step launch of the aquarium.
1.Before launching, a new aquarium should be thoroughly washed with baking soda or households. soap without additives (after which it must be thoroughly washed with water). No detergents can be used.
2. Then on the back wall of the aquarium paste the background and set it in a permanent place. The surface of the stand must be perfectly flat and not sag, otherwise the glass may crack under the pressure of water, a soft bed of foam rubber, 7 mm of foam or spongy rubber must be put under the bottom.
3. At the bottom of an established aquarium, the ground is laid. Before laying, it must be thoroughly rinsed under running water (if purchased) and boiled (if you have collected yourself). The thickness of the layer should be about 5 cm, fraction 4 - 5 mm.
4 install equipment (filter, heater, necessarily a thermometer to monitor the temperature of the water). We do not include anything in the network.
5. Set the scenery (grotto, snags, stones), everything is chosen to your taste.
6. Заполняем аквариум наполовину водой можно лить из под крана не отстаивая, включаем грелку и фильтр и оставляем в таком состоянии на 3-5 дней (лучше неделю) . Свет не включаем. Через 2-3 дня вода помутнеет - не пугайтесь. Идет установление биологического равновесия через несколько дней она очистится.
7. A week later, we turn off the equipment and start planting plants (in the first stage, it is better to take the not whimsical Valisneria, Strelloist, Gyrofilu) to throw a large bunch of Rogolof onto the surface. turn on the equipment again (now it should work constantly).
8. Next light. First, we start to turn it on at 6 o'clock and add every day by an hour in this way to the 10-12 hour day.
9. Now we have patience and wait for another 7-10 days. During this time, you will see that the plants that were planted before and stood at random straightened and started to grow. The time has come to determine the aquarium community.
You do not have a very large aquarium, so at the first stage it is best to start not very capricious.
1. This is a flock of Haracin taken from all 5 - 6 pieces. Danio, Rasbory, Thornetia, Kordinals, Minor, Neons
2. You can take a flock of cherry, fire, scarlet Barbus (also 5-6 pieces)
From cichlids look at the Apistograms of Ramirezi butterflies. Your aquarium volume is 2 maximum 3 pairs. Be sure to cover. Territory fish.
Labyrinth: Gourami, Lyaliusa, can Sword, Mollies at the bottom of catfish Ancistrus, a flock of 5-6 speckled corridors, Golden.
And lastly. Do not try to populate the aquarium immediately completely, since the startup process takes about a month. The new aquarium can not cope with a large number of physiological secretions, so it would be wiser to carry out the settlement in several stages, within a few weeks.


First you just need to fill the aquarium with fresh water, cover the soil and let it stand for a week. Then you can install the filter and the compressor and plant the plants and let it stand again for a week. And after that you can run there fish. And the first time the water will be turbid - this is normal, the first time to change the water in any case is not necessary, you just need to add to replace the evaporated one - the bacterial balance will be established, and the turbidity will pass. And then periodically make partial and full water changes. Well, self-cleaning filter. Naturally, water should be poured without bleaching powder - defend in a wide tank for 3-4 days.

How to run a new fish in the aquarium?

Elena Gabrielyan

The first and most important rule of all newly acquired fish before being released into the general aquarium is to be kept in quarantine in a separate aquarium without plants and soil for at least 3-4 weeks. Otherwise, you risk bringing the disease if there are already other inhabitants in the aquarium. Then, in addition to the temperature of the water, it is also necessary to level its chemical composition - in all aquariums it is different. To do this, every 20 to 30 minutes, you add half a glass of water from your aquarium to the package with the fish brought in and for 2 to 3 hours if the transfer process is longer even better and only after that you can release the fish into the general aquarium. Feed them the first day is not necessary.

Look, the fish you should have in a special package and you drop the package in aqua and hold for 2 minutes and then open the package and release the fish. feed immediately is not necessary because they will not have the "stress" in the evening, try to give a scarlet poros ...

At first, the nodo should lower the package with the fish into the aquarium water so that the temperature in the package and in the aquarium are approximately the same, otherwise the fish will die from a sharp temperature drop. And then the fish will do everything themselves !!!))) And they feed the fish mostly 2 times a day !! ! If you took the fish in the morning, then you need to feed them only in the evening, and if in the evening, only in the morning! And even before “landing” the fish in the aquarium, you can hold each fish in very saline water for about 3 seconds (not more), so they will not bring the disease into the aquarium.

Vooyusche fish should be put on dark times of the day. If you already have fish, then you need to pour one glass of water from an aquarium with fish so that new fish smell the old fish and then do not fight. Feed the fish should be an hour after transplanting into the aquarium. Feed need a little bit. And it is impossible to switch to another feed sharply.
