high-backed red-tailed goldfish? High-backed red-tailed goldfish is a large ornamental fish living in the middle and upper waters. The tank chosen should be at least 1.5 meters long and 0.7 meters high. They are lively and active, like to jump, when raising the fish tank must be covered, otherwise they will jump out of the fish tank carelessly. They belong to carnivorous fish, and can choose active baits such as frogs, loaches, goldfish and grasshoppers for daily feeding. When arranging the fish tank, we can consider placing a surf pump in the fish tank, which can not only increase the dissolved oxygen in the water, but also generate water flow, so that the goldfish can maintain a certain amount of exercise. When raising this kind of fish, we should pay attention to the stability of water quality, temperature and other environmental conditions, and it is still difficult to raise it.

When feeding, attention should be paid to minimizing the content of chlorine and nitrite, so as not to affect the health of goldfish.
2. Illumination: At least four hours of illumination are needed every day, and it is better to use daylight during the day. Long-term use of light will darken their backs.
3. Change the water: When changing the water, be careful not to make the PH value and temperature change suddenly, otherwise they will die suddenly. If the fins and scales of goldfish fall off, it is caused by frequent and excessive water changes. A pause in the water change can make things better.
