Scientists in China and Japan have withdrawn several species of goldfish. Many believe that caring for these fish is very simple because they are very popular. But not so simple. Very often they are presented for any merit, or simply as a gift. A person after such a gift involuntarily thinks about how to take care of a Chinese goldfish, so that she is comfortable in her new place of residence.
If the golden fish is not properly cared for, it will not last long in the aquarium. It happens that she lives only a few days. In order for the care to be correct, it is necessary to take into account the condition and size of the aquarium and what water should be poured. No less important is the feed. When choosing an aquarium, you need to know that in small aquarium fish do not live long. The size of the aquarium depends on the size and number of fish. Still need to know that the water should contain a lot of oxygen. No less important and the contents of the aquarium. For example, you need to properly decompose the gravel in the aquarium. On this gravel live bacteria that reduce the level of ammonia in the water. The water temperature for goldfish should be equal to 21 degrees, no more and no less.
When migrating a Chinese goldfish, it takes time and patience of the owner. Beginners will be surprised at the scientific approach to resettlement. But this experience will be very useful for adults and children alike. Here are the 10 main rules for caring for a fish, which you need to know for everyone who wants to have a goldfish:
Aquarium
It is necessary to have a large enough aquarium. A round classic aquarium is not the best option for keeping such a fish, despite the opinion of most people. In it, the fish will not feel comfortable and therefore will not last long. A small place for swimming, lack of oxygen and refracted light greatly affect the health of the fish. In such an aquarium it is very problematic to put oxygen dispensers and water purifiers and at the same time not to touch the decoration of the aquarium.
The best place to live for goldfish is a regular rectangular aquarium. It is easier to decorate with plants, stones and other decorations. Experienced owners of aquariums advise not to exceed the number of fish more than 2-3 per gallon of water. Thus, ten liters of water can accommodate only 2 fish. If you increase the number of fish, the water pollution will also increase, which will make goldfish uncomfortable. Also there will be more work for the owner of the aquarium.
Maintaining biobalance in large aquariums is much easier. However, for a more comfortable environment, do not increase the amount of water .40-50 liters per individual is enough. To place the aquarium is best close to the sunny side, since without sunlight goldfishes lose their color, and plants can wilt. Solar lighting can be replaced by ordinary electric light.
Aquarium filter
The filter for the aquarium is better to buy with the function of air injection. Goldfish simply need oxygen-enriched water, because unlike labyrinthine fishes, a golden Chinese fish breathes air dissolved in water.
Insufficient oxygen in the water can be determined by the behavior of the fish. If she swims at the surface and tries to grab the air with her mouth, then it is not enough in the water. With this behavior, you must immediately change the water or increase the purge. To replace water, it is better to use tap water, which has been settled for a day in a separate vessel. In a large aquarium with a small number of fish it is desirable to replace a tenth of the water with tap water. Do not completely replace water. This will disrupt the biobalance and the fish will feel uncomfortable.
In an aquarium without blowing an enormous role is played by aquatic plants, saturating the water with oxygen. But the plants are polluted with particles of waste in the water, besides, the tender grasses of the fish simply eat. Therefore, you need to choose strong plants, with a good root system and stiff leaves: Japanese sagittaria, anubias or the most hardy, for example, elodea - are ideal for choice.
Gravel
Correctly choose the interior of the aquarium. At the bottom must necessarily lie gravel. It is inhabited by bacteria that lower the level of ammonia in the water. Only gravel should be not too small - goldfish can eat it.
Settling in the aquarium
Do not immediately populate gold Chinese fish in the aquarium. It is necessary to wait, when in it the appropriate biobalance is formed. To do this, it is recommended to settle the snails first in the aquarium, so that they slightly "pollute" the water there. When ammonia is filtered out by bacteria, the water will become habitable. This process can take time from a couple of days to a week.
Feed
Just proper care for the golden Chinese fish will not be enough. Fish also need the right food. There are many different feeds, granulated and in the form of flakes, designed specifically for such fish. You can crumble a boiled egg or finely chopped lettuce in the water of the aquarium. Fish eat them with great appetite.
You can not give a lot of food to the goldfish, so that it does not overeat. To determine the amount of food needed for a fish, it is enough to observe it at the time of your first feeding. Need to pour the feed and see how much it will eat in these three minutes. And remember - a goldfish can eat a large amount of food if it is given too much.
Testing of water
From time to time, it is necessary to test the water for pH (not higher than 7-8), as well as the amount of nitrites, nitrates and ammonium. Ammonium and nitrates are very harmful to aquarium tenants, so if their content is greater than zero, this is bad. The norm of nitrates is up to 40.
Thermometer
It is necessary to place the thermometer in the aquarium. In cold water, a goldfish will not survive, as it is a tropical fish species. The best temperature of water is a temperature equal to 21 degrees.
Diseases of goldfish
It is advisable immediately to find out about the diseases of the goldfish, since knowledge of the symptoms can help you to quickly learn the disease of the fish, so you can save her life. Raised dorsal fin is an important feature of goldfish health. They must be active and rush to food with great hunger. Do not allow damage to the fins and eyes of the fish. A muddy scurf on the scales is a sign of exhaustion.
The content of a goldfish is a very fun and interesting activity.
