Which aquarium to put a goldfish?

Often in various foreign films you can see a lonely goldfish in a small round aquarium. But alas, many people who buy themselves the same aquarium from the movie do not think that it is not part of the decor of the room, but a habitat for a live fish.

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

Goldfish come in several varieties, but more common are the species of voile tail. If you just pour water into a 10-liter round aquarium and run a voiletail there, the fish will die before they get bored of loneliness. For fish, the round shape of the aquarium is extremely unpleasant, it is disoriented in such an aquarium. Goldfish do not like cramped habitat conditions. Fish need angles, and in a round aquarium, it will move a little and, as a result, it gets fatter. By the way, growing fat is not a problem for a goldfish, by its very nature it is very voracious, therefore it is necessary to feed it strictly metered and arrange fasting days.

In order for the voiletail to please its owners for a long time, it is better to choose for it a rectangular aquarium with a volume of not less than 50 liters, sprinkle the soil, plant the plants, besides you can provide the aquarium with an external and internal filter. Plants will not only supply the water in the aquarium with oxygen, they can become a shelter for the fish from the sun and the breadwinner on fasting days, the fish usually plucks the leaves of algae and collects particles of old food from them. For a comfortable life, the water temperature must be maintained at a level not lower than 22 degrees, otherwise the fish may freeze.

Maintenance and care of goldfish

Goldfish are excellent pets for beginning aquarists, whose care is simple and interesting. The maintenance of this type of fish in the home has become available hundreds of years ago, this is one of the first ornamental fish that was settled in a glass tank. In China, they were kept in porcelain bowls, today unique aquascapes are created with the similarity of a natural biotope so that pets can live comfortably. How to properly care for them in the aquarium to extend their joy of life?

The rules of settlement in the aquarium

  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.

  2. Place a quality filter in the tank. The goldfish is known as an avid "muddy" that leaves a lot of trash behind. 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.
  3. 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.
  4. 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.

  5. 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.
  6. 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.
  7. 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.
  8. 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.

Terms of care and maintenance

  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.

  2. 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.
  3. 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.
  4. 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.
  5. 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.

  6. 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.
  7. 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.

How, what and how much to feed Goldfish?



Goldfish - extremely playful, cheerful and voracious creatures. They quickly get used to the person of their breadwinner, and as they approach the aquarium, they jump out of the water like piranhas with hungry eyes. This behavior of your waterfowl pets can be repeated 10 times a day, but this does not mean that the goldfish are hungry all this time. This is just a conditioned reflex. It is necessary to feed your pets 1-2 times a day with one pinch of dry food. This is quite enough for their normal growth and development. If you feed more often, the fish will behave very sluggish, in addition their life expectancy will be reduced.

Despite the fact that the process of feeding goldfish can bring you a lot of pleasure - do not abuse it. In fish, there is no sense of saturation. Do not forget about it. So do not overdo it. And your pets will long please your eyes and soothe raging thoughts.
And now from the lyrics, to the point!

Goldfish need a balanced diet. Their diet should include both live food - bloodworm, artemia, daphnia, rotifers and other food: dry and especially vegetable.

If we talk about proportions, then in my opinion for goldfish, this proportion looks like 40% live, dry and 60% vegetable food.

Live food, adore all the fish and gold is no exception. When keeping Zolotuh in an aquarium, it is better to use frozen live food, as they are safer than full-scale.

Dry feed - a universal remedy for feeding any fish. Manufacturers of aquarium feed took care of the usefulness of the diet. Therefore, if you wake up to feed goldfish only with such food, then this will be quite enough for their well-being. But if you want to feed your goldfish to be elite))). It is necessary to introduce vegetable feed and only natural.

How is this achieved ?! Yes, very simple. You need to breed Leopard or RicciaWell, it is very golden love this aquarium vegetation.

Here, please see how much duckweed grows in my week in an aquarium with scalars. All she goes to feed goldfish.
Economical and non-GMO!

As it is known, duckweed and riccia grow very quickly and do not require special conditions for maintenance. For a week you will grow it on a scale sufficient for goldfish to feed. It should be diluted in a separate aquarium and transferred to scrofula 2-a - 3 times a week. That's all you need.

It is necessary to distinguish the feeding of goldfish in the aquarium and in the pond.

For feeding goldfish in a pond, it is recommended to use meat chips mixed with bread, as well as hard boiled cereals: buckwheat, oatmeal, millet, etc. The pond must be with vegetation !!!

If anyone is interested in this question, I recommend you to talk with our user "Muri", she is a noble ruler of goldfish in the pond!

I feed my goldfish with the following formula:

Resurrection - live food, Monday - Wednesday is dry and substitutes, Thursday - duckweed, Friday - Saturday - dry and duckweed.

On such a feed my scrofulous - fat and fluffy !!! :)

What aquarium is needed for 2 goldfish?


two gold need 70-100 liters, provided that there are no neighbors.
In addition to feed, primer is needed, which is obvious. I do not recommend marble water - the water becomes very hard from it, and not all fish like this water. in pet stores varied selection of soil. You can take a color, you can have a natural color, this is someone you like. You can even collect and process on the river.
It is very important to have a powerful filter with aeration. Goldfish are demanding for the presence of oxygen in water, and powerful filtration is necessary for effective purification of water. yet golden large grow and spoil a lot.
no heater needed - these fish belong to cold water. for them the optimum temperature is 23-25 ​​degrees.
live feed is better to use. bloodworm is fine. but before they feed the fish, it needs to be frozen. just put it on a bag in a thin layer, roll it up and put it in the freezer for several hours. but you can also feed them with dry food. suitable as a simple daphnia and gammarus, and branded, which are much more expensive, but quality. Small fish need to be fed every day 2 times. adults once a day, while once a week do not feed - arrange a fasting day. overfeeding is not worth it. It is also worth doing vegetable dressing. You can buy special vegetable flakes, and you can throw them aquarium plants with soft leaves. the best option would be a rogolnik. but if you want to plant plants in an aquarium, then you need to choose only with hard leaves and a powerful root system, otherwise they will be torn out and eaten.
I almost forgot. it is important to replace part of the water with a new one once a week. enough to substitute 15-20 percent of the volume. water must be defended for 2-3 days.

Alexander Ognev

On 1 cinderella, it would be 40–60 liters in an amicable way, so it is necessary for a couple of liters 80-120. Denis and Rustam, your data is outdated by 50 years at a minimum, when neither ammonia and nitrates were tested. now all the scrofs are imported from Asia, where they are kept in ponds, they are accustomed to the fact that there is a lot of space for 1 individual, so an average of 50 liters is needed for 1 scrambler. in 20 - 60 liters 2 scrofula and 1 year of non-survival, and even then still small, because adults in such a volume will suffocate from their own feces and other waste of their vital activity. scrofula - piglets and they always dig in the soil and lift deposits, they need a very powerful filtration and aeration. and do not believe the sellers, they will lie to you that they are allegedly not from Asia, but it will not be so! good luck

How to prepare an aquarium for goldfish?

Dimka Miller

Sorry, but in such conditions it is impossible to contain a goldfish (it is even one! And you have several!)
So, you have decided to opt for certain goldfish and have already bought them a good aquarium of about 30 liters. What to do next? Give up the goldfish! Or choose another aquarium. If you do not have just any opportunity to purchase a larger aquarium, stop your choice on other fish. Do not torture them and yourself, there is a huge number of other aquarium fish, no worse than gold, for which this capacity will be just a fabulous house. If your solid and unequivocal choice is goldfish, you will have to spend more money on capacity.
- in the photo my aquarium of 85 liters, which contained this telescope and a red cap, each palm-sized + a pair of antsistrus (slightly distorted, but the front wall of the aquarium is curved and the photo was taken on a mobile).
P.S. On sale there are round aquariums "with a full cycle" - as well as square, equipped with covers with built-in equipment.

Olga Alekseeva

Round aquarium is not good for fish at all. And for gold, all the more. They need a very large amount of aquarium. The norm is about 100-150 liters per fish. Goldfish are heavy to care for. They are voracious and dirty. Requires active filtration and aeration of water. If you are a beginner, I do not advise you to start goldfish.


1. no round! take the usual rectangular, because:
- does not distort the view
- fish in the round is not comfortable
- there is no possibility to attach a filter, heater, etc. to the walls ...
2. the volume for two gold should be 50-60 liters, taking into account that there will be no one else with them.
3. in the aquarium should be:
- large soil. small gold can swallow or it will stick in the mouth when it searches for food at the bottom
- powerful filter, gold spoils a lot
-plants at will. if alive, stile-leaved with a powerful root system so that they are not pulled out. soft gold leaves will eat
-heater is not needed. golden - cold-water fish. The optimum temperature for them is 22-25 degrees. if the temperature is 20 and below, then a heater is needed. if the temperature is 28 and higher, then you need to lower it, otherwise the fish will die
4. feed small need a couple of times a day, adults once a day, while doing a fasting day once a week (do not feed). any feed is suitable - from simple types of gammarus and daphnia, to the more expensive tetra. but it is better, of course, to feed them with live food - bloodworms. from it, unlike dry, water practically does not deteriorate. live food is best frozen, otherwise it will spoil in the fridge in 2-3 days. freeze like this: put a thin layer on the bag, wrap it in the freezer. When it comes time to feed the fish - just break off a piece and throw gold.
also gold requires plant supplements. this can be as well as dry plant-based foods, as well as aquarium plants such as felid and the like.
5. once a week you need to change the water. it is enough to drain 10-15% of the water by volume and pour freshly settled. You need to defend for at least two days, but as an option you can use the drug "anti-chlorine", then after adding it, water can be poured immediately.
as well as the contamination of the soil it is necessary to siphon. siphon can be bought at any pet store.
6. If you decide to plant neighbors for them, then you need to count on them as well.
do not get along with them:
-aggressive and cocky: barbs and cockerels (peeling off the tail), cichlids (even those species with a calm character show aggression during spawning)
- predators (besides cichlids also applies to some species of catfish)
- small fish (to be eaten)
get along:
- calm: gourami, liliius, mollyzii, petsily, etc.
-size, larger and those that do not fit in your mouth.

What should be a goldfish aquarium round or rectangular ??? It is very necessary to buy food soon, but I do not know which one.


A goldfish is big and the aquarium needs a large 200 liters and a bigger pool is even better, and round aquariums are usually too small and not suitable for a goldfish - it's like a person living in a closet and there is also a toilet and a kitchen there.

Marina Koltunova

I explain popularly. I work in a pet store. We are periodically sent to all thematic studies and seminars. So about the round aquariums. It turns out that there is even an international convention prohibiting the production of round aquariums (Russia, of course, not signed, because we have such problems on the drum ...) Do you know why? I quote, "Because a fish behind a curved glass receives distorted information about the world, as a result of which it has a lot of stress, which can adversely affect its well-being and even longevity ..."


As far as I know, round aquariums are still quite small in size, and a goldfish needs a large amount of water. Stupidity here you wrote that the round looks aesthetic, do not believe. More aesthetic, he looks in the picture. And in life, a round can be used either as a short-term blender (or for short-term shooting of beautiful photos) or for living fish that breathe atmospheric air, for example, cockerels. for goldfish, it is necessary to purchase equipment - a compressor, a filter, and, if necessary, equipment for heating water. And where will you put all this in a round aquarium? Will this farm hang in the center? And about the fact that the round is easier to clean ... Here the rectangular is cleaned with a special scraper round than it is not clear ... Take the best rectangular at least 50 liters. My opinion.
