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 live fish.
Goldfish come in several varieties, but veiltail fish are more common. If you just pour water into a 10-liter round aquarium and run the veiltail there, the fish will die before it gets 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 living conditions. The fish needs angles, and in a round aquarium it will move little and, as a result, get fat. By the way, getting fat for a goldfish is not a problem, by its nature it is very voracious, so you need to feed it in a strictly metered dose and arrange fasting days.
In order for the veil tail to please its owners for a long time, it is better to choose a rectangular aquarium for it with a volume of at least 50 liters, fill in soil, plant plants, and you can also equip 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 from the sun's rays and a breadwinner for the fish on fasting days, the fish, as a rule, plucks algae leaves and collects particles of old food from them. For a comfortable life, the water temperature must be kept at a level not lower than 22 degrees, otherwise the fish may freeze.
