How to care for goldfish in an aquarium

maintenance, care, compatibility

  1. Buy a wide aquarium. Make sure that there is enough space for the pet in the tank. For a voile-tailed goldfish, approximately 45-90 liter aquarium is needed. The goldfish grows fairly quickly, and if you plan to provide it with proper care, buy a tank in which already mature individuals will fit, which will save you later from replacing the reservoir with a more spacious one.

Look at the well-designed goldfish aquarium.

  • Place a quality filter in the tank. The goldfish is known as an avid “muddy” that leaves behind a lot of garbage. Your filter is obliged to comprehensively clean the water, preferably 10 times in 60 minutes. If you have a 20-liter aquarium, you will need a filter that has the ability to pump at least 200 liters. at one o’clock. Another suitable filter that pumps more than ten times the volume of water in the tank.
  • A nitrogen cycle should be established in the aquarium. You need to buy a water device with an indicator that clarifies the saturation of water on nitrites, nitrates and ammonia. Do not buy test strips, they will not provide an accurate result. Use a special liquid to eliminate chlorine in order to release toxic chlorine from the water. Line out the bottom of the aquarium with a pea-sized gravel (small volume so that the pets cannot choke). Make sure that the pebbles or gravel do not contain metal fragments, since pebbles with metal have every chance to harm creatures if the dissolution of toxic elements in water happens.
  • Get a small amount of decorations and decorations. Animals would love it, and diversify their small house. Do not purchase decorations with small holes, so that the goldfish could not sit there. Take into account the size of a mature individual (sometimes they grow to the thickness of a grapefruit!), And even then set the scenery. You can add algae; goldfish like to nibble on living plants, as a rule, they are: anubias, waltz, cryptocoryne, and others.


  • Buy goldfish that have a healthy appearance. Be careful with the aquarium, where there is an inanimate fish, this may indicate the symptoms of the disease or the wrong care.
  • Do not launch the purchased fish immediately into the general aquarium. Leave it for a 2-week quarantine in a separately prepared container with infused water. Such a procedure will prevent fright and diseases that a fish could bring from a previous aquarium.
  • Contrary to the arguments, it is not recommended to place the voile tail fish in a round tank or a nano-aquarium. There she will be uncomfortable, her vision may deteriorate. Do not settle the fish in a tropical aquarium with heat-loving fish. Goldfish is a cold-blooded animal that hails from temperate latitudes.
  • After quarantine, a goldfish can be launched into an aquarium. Do not rush to run the fish in an unfamiliar aquatic environment. Upon returning home with a new resident, lower the closed polyethylene roll with the goldfish into your tank for approximately 10 minutes. This will help the fish adapt to the temperature in the tank. Following this, add a few drops of water from your aquarium to the package with the fish, and wait another ten minutes. Then with a net, transfer the fish leisurely to the aquarium. Pour the packaged water into the sink or gutter. This process not only limits the stress to the animal, but also prevents water pollution in the reservoir tank. Then schedule how to care for your pet every day.
  • Watch a video about goldfish content.

    1. Feeding the fish should be carried out twice a day, flaky or granulated feed. Goldfish can still eat frozen, live, vegetable, artificial foods. Very much like peeled peas, which is useful for digestion. Vegetable food (cucumbers, zucchini, salads) finely chop to make it easy to swallow. Overfeeding pets should not be – it is dangerous to health.


  • Quality maintenance and care must take into account the parameters of the aquatic environment. Test water for nitrites, ammonia and ionic hydrogen (hydrogen) pH. Ammonia should be 0, the pH should be 6.5-8.0, and the degree of nitrate is allowed below 20. If this degree is above 40, then you have a very fish-filled aquarium, or you do not replace the water at the right time! If ammonia and nitrites were detected in the water, therefore, bio-filtration in your tank has not yet been established. Permissible water temperature is 15-20 ° C.
  • Caring for the tank should be conducting a weekly replacement of water. Once a week, change 30-50% of the water in the aquarium. Updating all aquarium water is dangerous for wholesome unicellular organisms that cleave fish waste. It is mandatory to do the process of dechlorination before making fresh water in the aquarium.
  • Clean the gravel one in 2 weeks. Do the procedure using a vacuum gravel filter device that cleans the litter while draining the water. For tropical aquariums, it is recommended to perform this function once every 30 days, but for goldfish (there is more than enough waste from them), always provide a clean environment.
  • Spend time with goldfish as often as possible. Caring for her involves constant communication and eye contact. When she gets used to you, the content of the pet will be even more beautiful. Veiltails will begin to recognize you, and when you take care of them, they will begin to recognize your hand while nursing, and not be afraid of it.

  • If your goldfish happened to be on the floor, or a cat got out of the aquarium (this happens often), quickly wet your hands, and with wet hands, run the fish back into the pond. So she will not be under great stress. Be sure to cover the tank lid so that such cases do not recur.
  • Keep track of the scenery in the tank. If you notice sharp corners, rotted trees, broken glass or ceramics, immediately remove them from the tank. All decorations before placing in the aquarium should be processed in boiling water.
  • The capacity of an aquarium for a goldfish must be at least 50 liters. In such an aquarium, you can settle up to 6 individuals, it is dangerous to settle more – they most likely will not survive due to excessive pollution.

    You can share your neighbors with goldfish. It may well get along with them scalar, catfish.

    Before you start an aquarium, familiarize yourself with all possible diseases of goldfish. Knowing the symptoms will help you quickly recognize the disease and save the fish. Here are some basic rules for keeping a goldfish in an aquarium:

    • Do not skimp on the “living space”. For a goldfish you need a large aquarium. This is more convenient, it is easier to maintain biobalance.
    • Buying the right filter. You need to choose an aquarium filter with the ability to pump air. A goldfish needs oxygen-rich water.
    • The ideal bottom for keeping fish is gravel. It contains beneficial bacteria. These bacteria consume ammonia and thus lower its level in water. Try to choose coarse gravel, small fish can eat.
    • Do not rush to populate a new aquarium. Let the biobalance settle in it. You can run snails and catfish there for a while. They a little “pollute” the aquarium, then the water will be suitable for running the fish.
    • Periodically check the following water tests: pH level (it should be 7-8), ammonium level, nitrites and nitrates (up to 40 is considered normal).
    • Place a thermometer. Goldfish is a tropical species. In cold water, it simply will not survive. The ideal water temperature for goldfish is 21 ° C.
    • Change water regularly. For an aquarium of 5-10 liters, it is enough to change 20-30% of water. Doing this is enough once or twice a week. In the new water, you can add a special conditioner. Complete replacement of water can disrupt the biobalance and harm the inhabitants of the aquarium.

    It is also important to decide what to feed the animal. If we talk about the choice of the required aquarium, it is worth saying that in small aquariums these fish die. The larger the fish itself or the greater the number, the larger the volume of the glass dwelling should be.

    Also, future owners should know that water must be enriched with oxygen. The important point is the choice of “content” of the aquarium. For example, you need to put gravel on the bottom, because bacteria live on it, which absorb ammonia and its level decreases in water.

    In order to contain one goldfish you need:

    Aquarium filter, with the ability to pump air – 1pc.

    How to contain goldfish

    How to keep a goldfish in a round aquarium :: how to care for a round aquarium :: Aquarium fish

    The popularity of round aquariums and goldfish is due to two main factors – goldfish are among the most hardy and unpretentious aquatic inhabitants, and round aquariums are in harmony with any interior and are easy to clean. However, despite such advantages, there are several important rules that concern the content of fish in such tanks.

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


    Goldfish are considered one of the hardiest inhabitants of aquariums. They are able to withstand fairly significant cooling of water or its heating.

    It is recommended to equip aquariums with special devices for temperature control, but goldfish can simply change the water more often and provide the necessary care. In their natural environment, goldfish can survive even in icy water.

    They are among the most enduring aquatic creatures.
    In an aquarium with a goldfish any aquatic plants must be present. Just a few twigs are enough.

    At the bottom of the vessel, you can pour gravel or place decorative balls that will turn a round aquarium into a kind of designer decoration of an apartment or office. Sand in this case is not recommended.

    In a round aquarium, a small area, and dust can instantly pollute the water and make it detrimental to a goldfish.
    It is very important to provide the aquatics with sufficient light. It is better to put aquariums in well-lit places or use additional devices.

    Due to lack of sunlight, the goldfish may die.
    Keep in a round aquarium a few goldfish is not worth it. The calculation of the required area should be made in accordance with the proportion – 1 cm of the body length of the fish per 3 liters of water.

    Otherwise, the inhabitants of the vessel simply do not have enough oxygen for normal life.


    Keeping a goldfish in an almost empty aquarium is not recommended. The fact is that with a minimum amount of vegetation, the walls of such a vessel create the effect of a lens. A fish in such an atmosphere will be in constant fear, which will lead to serious consequences from stress.

    Quite often you can see completely empty aquariums with goldfish. However, it is better not to create such conditions for a pet.

    Fish vegetation is a supplement to the main food and source of vitamins.
    In a round aquarium, you must create the most comfortable conditions for its inhabitants. To do this, you will need a small lighting system, a compressor for water treatment and a special heater. For round aquariums, special compact equipment is produced, which does not take up much space and does not spoil the appearance of the original vessel.

    Quite often, for example, you can find round aquariums with special lids in which all the necessary systems are mounted.
