Fish care

maintenance, care, compatibility

All aquarists, both beginners and experienced, it is important to know how to care for aquarium fish correctly. In fact, their care begins with the purchase of an aquarium, because of its shape, size, material depends on how comfortable the life of pets will be.

Aquascape, feeding, compatibility with other aquatic organisms are also important conditions for the harmonious life of the fish. To ensure proper care of the fish at home, you need to familiarize yourself with some rules.

Care for water pets should be constant and quality. Cleanliness is a guarantee of health and carefree life, both for the owner and for the pet. Instructions for the care of an aquarium with fish:

  1. Regularly make water changes to fresh and clean. It is easy to get such water – dial the required amount from under the tap into the glass container, leave for 2-4 days, bring to the required parameters (check with indicators). Then pour into the tank. In an aquarium of 200 liters, you need to replace 20% of the water; in a 100-liter one, you can replace 30% of the water. The procedure should be repeated once a week.
  2. Constantly siphon the bottom of the reservoir funnel, removing the remnants of uneaten food. Do not turn off the compressor with aeration, filter, heating without special need.

  • Every day, watch the pets – their appearance, behavior. If you notice a change – prepare a quarantine tank. Perhaps the fish is sick, and she needs special care.
  • You should have a scraper for aquarium glass, which perfectly cleans hard surfaces from algal fouling. Stone rocks and snags can be cleaned with a brush. If the surfaces are not cleaned in a timely manner, the biological balance will be disturbed, which will affect the well-being of the fish.
  • Simple instructions: how to care for fish in an aquarium

    Argued that the maintenance of fish does not require time and financial costs. Experienced aquarists will talk in detail about the complexity of this lesson, which requires care and unhurriedness. You control a small underwater world that cannot exist without competent support.

    For beginners, help how to care for the fish in the aquarium (point by point).

    Excessive care for such pets is not required. To understand the process will help the instruction.

    How to care for fish in an aquarium, even children can remember.

    How to choose the inhabitants? How to care for fish in an aquarium? The manual will give answers to these questions.

    Decide in advance on the species composition of the ichthyofauna to simplify the process of leaving and to prevent conflicts. Focus on the size of the fish: large and small individuals can not live together.

    For many decades, viviparous fish have been very popular with aquarists. They do not lay eggs, but immediately give birth to viable fry, which can independently move and feed.

    Characterized by these types of ease of care, they do not need to create special conditions for reproduction. However, the fish have a large range of colors and shapes.

    Instructions on how to care for fish in an aquarium, the points suggests:

    • Regular reading of the water thermometer. If there are deviations from the recommended parameters for this type of fish, the heating is turned on.
    • Viviparous ichthyofauna suitable temperature from 18 to 28 ºC. But each individual species has its own preferences. Reproduction will occur only in this narrow temperature range.
    • Control of purity and hardness of water. Every 7 days, one third of the medium is removed, replacing it with a new one.
    • Check the filter element and compressor, without which the normal existence of the inhabitants is impossible.
    • The aquarium should be lit from 10 to 12 hours a day.
    • Feed the inhabitants need 1-2 times a day. In the presence of fry, the number of meals is increased to 4. A portion of food is placed in the feeder, which is usually eaten in 5-10 minutes. Residues must be removed (to prevent rotting).

    The given instructions on how to care for fish in an aquarium will help beginners to orient themselves in the basic requirements for their maintenance and feeding. More detailed information should be studied for each specific type that you have.

    It would seem that difficult to care for the aquarium? I fed the fish, and once a month I poured water, washed it with soap and boiled all the stuffing, filled it with clean water. Everything sparkles the first two days.

    The fish are probably happy, they only live for some reason not for long. Of course, we described an extreme case of amateurish zeal, but let’s still examine the basic principles of caring for our little body of water.

    Being a real ecosystem, the aquarium at the same time is small in size and is an open-loop system, and therefore unstable. Organic matter comes in from the outside in the form of at least fish food, it is inhabited by animals that feed, grow, produce waste and multiply, live plants that consume some substances from water and release other substances into it.

    Therefore, to maintain an artificial reservoir in the form it was conceived – clean, bright, smelling the freshness of a forest lake – some, sometimes significant, human effort is required.

    Caring for an aquarium usually takes 10-20 minutes daily and an hour and a half extra once a week.

    Daily care procedures include:

    • check equipment operation;
    • inspection of fish;
    • feeding fish (this is a very broad question and a topic for a separate article).

    During the launch of the aquarium or when there are some global changes in it, for example, when populating a large number of large fish, replacing the biofilter filler or installing carbon dioxide supply equipment, it is also advisable to test the aquarium water daily, checking the level of ammonia, nitrite, pH and other parameters.

    • water change;
    • cleaning the soil from excrement, food residue and other waste, siphon, if necessary;
    • cleaning the glass from algae;
    • washing the filter (not always, depending on its type);
    • care of plants (dressing, pruning).

    Testing water once a week for nitrogen compounds, phosphates, hardness and acidity is also very useful for monitoring the condition of the aquarium, but in a stable and prosperous bank is not mandatory.

    Inspection of fish is most convenient to carry out during feeding, when even the secretive swim out of their shelters. It is necessary to check whether all the fish are in place, whether their appearance has changed (there are no stains, sores, wounds, reddenings, and the like) and behavior (how active they are, willingly take food).

    Equipment inspection is usually done in the morning after turning on the lamps. You need to make sure that the thermometer has the required temperature, the light is on the heater, the filter jet has the necessary power, the aerator or compressor, if any, is working with proper power, all the lights are burning exactly and brightly.

    If everything is in order, tasty feed the fish and enjoy our wonderful beautiful and stable ecosystem until the day when it comes to clean it.

    Usually, fertilizing plants is carried out once a week, if necessary. In addition, the leaves are covered with algae or eaten by fish and snails, the tops grown from the water are cut off, you can trim or weed out overgrown bushes and grass.

    These are the basic rules for caring for an aquarium. Of course, sometimes there are situations when additional, more complex interventions and manipulations are required, but if you master these basic principles, you will gradually be able to easily master all the other knowledge and skills.

    Video lesson about proper care of the aquarium:

    Guppies are unpretentious fish that can live without aeration and filtration of water. These are viviparous animals, like sharks, although they are distant relatives, their care is very simple.

    What else should you pay attention to before preparing a guppy settlement, and after? First, pick a big can – the bigger the better. Secondly, do not use old glass jars or plastic bottles that already emit toxic substances.

    Thirdly, it is difficult to place a filter in small jars, so all the “dirty” work will have to be done personally — wipe the inside surface of the container with a clean sponge, siphon the bottom, and replace the old water with fresh water every week. Fourth – do not put the jar or aquarium in place of direct sunlight. This can lead to water bloom and the death of animals.

    Fifth – with the help of a thermometer monitor the temperature.

    Care for such fish is a pleasure! Even a novice aquarist will not be afraid to admit that the first experience of keeping fish is associated with guppies. Simple species are less whimsical than breeding species that require strict maintenance.

    In any case, these cute creatures are a real aquarium miracle.

    Caring for an aquarium is like cleaning the house, the same simple rules for staying healthy and clean and regular. In this article you will learn how to properly care for a home aquarium, what important things there are and how often to do it.

    Why do you need to siphon the ground? What cleaners can I use? How to wash the sponge filter?

    Why and how to change the water in the aquarium? You will find answers to these and other questions.

    The sponge inside the filter should be rinsed regularly to avoid clogging and reducing the flow of water that it can pass through. But note that the old and dirty sponge is more effective than the one just bought.

    The fact is that the beneficial bacteria that turn toxic substances into neutral, live just on the surface of the sponge, in this very dirt. But, if the sponge gets too dirty, it starts to let in much less water.

    The amount of oxygen necessary for bacteria decreases, and they begin to die.

    Therefore, the sponge of the internal filter, which is small in power, must be cleaned every two weeks. The internal filter, which is much more powerful pump and more useful volume, is not clogged so quickly.

    It is possible to clean the sponge of the internal filter no more than once a month, for some models even more.

    The internal filter also has other materials that have a shorter lifetime. So, filters with activated carbon need to be changed once a month, otherwise they accumulate dirt and begin to give it back.

    Filters of primary cleaning (dense white fabric which the first takes water in itself), it is better to change every two weeks, but it depends on the aquarium itself.
    The biological filter, which is usually made in the form of ceramic or plastic balls, should be washed monthly. Please note that it is enough just to rinse, rather than bring to the factory state.

    Aquarium for beginners: care, content, useful video

    The motivation for writing this article was the frequent appeal of newcomers to aquarism at FORUM Almost every day, newly minted owners of the aquarium world ask their questions to which they either do not know the answers, or need advice, or have problems after the first launch of the aquarium.

    All who asked for help on the forum, did not go unheeded! Even if the newcomer had gross or absurd mistakes, I never scolded him, and tried to explain what was what planned.

    But, at some stage, I realized that I would not be enough for everyone and that I needed methodological material for beginners!

    Looking at the already written materials from the site, I saw a sufficient number of articles – “about the first steps into the aquarium kingdom”. But, all of them were scattered and only mutually complementary.

    After analyzing further similar materials on the Internet, my desire to write a decent, systematic material, only intensified!

    For constructive conversation, let’s break down the article into sections:

    1. AQUARIUM FOR BEGINNERS: arrangement, launch, frequent questions, problems.

    2. FISHING AND PLANTS FOR BEGINNERS: what are the issues that are necessary, problems.

    3. NUANS OF YOUNG AQUARIUM: rules that will help to avoid problems with the aquarium.


    arrangement, launch, frequent questions, problems

    To create an aquarium world, you need not only the aquarium itself, but also related products. Many beginners make the mistake of buying only the minimum part of the necessary equipment.

    And then they begin to run in a hurry in search of a product.

    Remember, as Captain Vrungel said: “How do you call a ship, so it will sail.” The first launch of the aquarium should be perfect – and this will be the key to the joy and pleasure from aquarium contemplation, eliminates possible problems and difficulties, and most importantly will give you invaluable experience.

    In the future, you can miss something, lazy … but not now!

    Other questions on the forum …

    Here’s another, for convenience, as a reminder – I give a list of what ponabitsya for a novice aquarist:

    – lighting, if not included;

    – aquatic organisms: fish, plants, mollusks, etc .;

    – food for prospective fish;

    – inventory: net, siphon, aquarium silicone, sponges, buckets. Secondary – hoses, valves, windshield wipers, other;

    Plus, I recommend to all beginners to buy immediately a means to stabilize the aquarium water. It is called the water stabilizer.

    Different brands have different names, here are some of them: Tetra Aqua Safe, Sera aquatan, Sera bio nitrivec … others. Read about them here AQUARIUM CHEMISTRY.

    The above articles fully disclose all the nuances of buying, installing and running an aquarium. Below are the blitz answers to the most frequent questions of novice aquarists.

    one. Question: Is it possible to put the aquarium on the furniture? In the kitchen?

    Bath and so on?

    Answer: Can. It is important that the surface of the furniture was solid and withstand the weight of the aquarium with water, soil and decorations.

    The aquarium can be placed anywhere, as long as direct sunlight does not fall on it. Cooking, bathing does not interfere with the life of the fish.

    2 Question: After the launch of the aquarium, the water turned cloudy – became whitish!?

    Answer: Nothing wrong with that. When you first fill the aquarium with water for the first time, the reservoir’s biobalance is not yet tuned, because This is a long process. Primary adaptation processes of aquarium water occur.

    The whiteness of the water will pass itself in 3-7 days.

    3 Question: What kind of water to pour into the aquarium? How often should it be changed?

    Answer: It is necessary to fill in at least a day separated water. Otherwise, you can run into trouble, for example, gas embolus.

    Yes … you can fill the aquarium with tap water – but, counting on it at random.

    The substitution of aquarium water is purely individual and depends on the size of the aquarium, the number of fish and plants, and other factors. In general, it is customary to replace water once a week.

    But, as the poll on our site shows, this is not a dogma.

    “How often do you change aquarium water to fresh water?”

    four. Question: Is it possible to decorate an aquarium with statuettes, shells, beads, etc.

    Answer: Can. But, you must make sure that the material from which the decor is made is not soluble in water.

    The same shells undergo a gradual dissolution in aquarium water, which increases, albeit slightly, the rigidity of aquarium water. Painted, plastic items are best not to use.

    Metal – are prohibited.


    what is necessary, issues issues

    Giving advice on choosing fish for a novice aquarist, you can immediately get rid of him with the phrase: “Choose unpretentious in the content, small fish, for example, from the family of petsilievi – guppies, swordtails, radishes, etc.”.

    But who thought it up that it is impossible to immediately start large, beautiful fish – the same tsikhlazom: severum, diamond or black-striped? If you properly care for them, then there will be no problems.

    And if you do not follow the aquarium and let everything go to chance, then the guppies will die in a week.

    Perhaps the main qualification when choosing aquarium fish are your abilities and desires.

    The opposite situation is with aquarium plants. It’s not so simple. The success of plant maintenance is LIGHT + SUPPLY + CO2.

    Their deficiency leads to the death or poor health of plants.

    Unfortunately, in the aquarium covers that come with, as a rule, there are 15-18 watt light bulbs, the power of which is insufficient for the normal existence of aquarium plants. Therefore, before you start a plant you need to study everything and prepare in advance.

    The initial way out of this situation may be unpretentious, resistant aquarium plants that are not pretentious to the conditions of detention.

    Below are the articles that fully and comprehensively disclose this section.

    rules that will help to avoid problems with the aquarium


    Unfortunately, they have such a job – to smell you as much as possible. Often the sellers’ advice is wrong and aimed only at one greedy enrichment at your expense.


    Actually this rule follows from the previous one – it is your weapon in the fight against lies. Your own opinion based on what you read is the key to success not only in aquarism.

    Read several materials on the topic of interest, for comparison and analysis.


    Do not rush, do everything thoroughly. It is impossible to get ahead of time – everything that was done in a hurry will collapse soon.


    Feed the fish once a day, “do not rub” the aquarium daily, do not fill the aquarium with fish and plants. In fact: aeration, filtration, normal water temperature and feed – these are the basic living conditions of the fish.


    This will give you the opportunity to quickly adjust the bio balance of the aquarium, to keep it clean, and in the case of illness of pets – to take action on time.
