1. Environmental requirements: Koi should be raised in a wide water body with sufficient oxygen, and the water quality should be kept clean and the water temperature should be well controlled. Koi is suitable for living in water temperature of 2 to 30 degrees, 20 to 25 degrees is the best. Don't let the water temperature change suddenly, otherwise it will make the koi uncomfortable.
2, feeding requirements: Koi is omnivorous animals, basically anything to eat, bread crumbs, steamed buns, insects and so on to eat. However, it is best to feed artificial feed, fish and insects, bread crumbs, duckweed and other foods. When feeding, it can be fed a small number of times, which is conducive to the health of Koi.
3. Rearing density: Koi requires higher oxygen content in water. In order to ensure adequate oxygen content, the density of the fish tank is not too large.
4. Selection of fish species: When purchasing koi, the culturist should choose healthy, harmless, non-scale-shedding, and bright-colored fish, which is better for feeding.
In addition, the newly bought koi should not be put into the tank immediately, but should be put into the tank together with the bag and let it stand for a period of time. Wait for the water temperature to be the same before pouring the fish into the tank, otherwise the koi will get sick. If you want to mix with other fish, you should put five thousandths of coarse salt to sterilize and kill insects. When raising Koi, we should pay attention to cleaning the fish tank in time to prevent long green moss and affect the water quality.
Koi fish need light illumination, because light illumination can make the color of koi fish beautiful. If the UV lamp is used, it can also play a role in sterilization. But can not use too strong light irradiation, time is not too long, open two or three hours a day.
