the outdoor water tank from freezing in winter? If you want to prevent the outdoor water tank from freezing in winter, you can bury half of it in the soil and wrap some quilts outside, so that it can keep warm and prevent the water in the tank from freezing. Usually, this kind of water tank can not raise tropical fish, because the temperature can not be well controlled, once the temperature is below 20 C, the survival of fish will be threatened, so we can only choose some eurythermic fish to raise.
is raised in the outdoor water tank? 1. Goldfish: Goldfish is a common ornamental fish, and it is no problem to raise it in the outdoor water tank. Because the fish itself evolved from crucian carp, it has a certain ability to adapt to the environment, and is not afraid of cold, even in winter, it will not freeze to death, as long as the water is not completely frozen.
2. Koi: As a high-grade ornamental fish, the size of Koi is relatively large, and the outdoor water tank must have enough space to raise it. As a eurythermic fish, it has strong adaptability to water temperature, can survive in the environment of 5-30 C, and is mild in nature, miscellaneous in feeding habits and easy to raise.
3. Tanichthys albonubes: Tanichthys albonubes, also known as Baiyun Jinsi, is a unique fish species produced in the south of China. Although it is a national second-class protected animal, it has been extinct in the wild. At present, all the existing species are artificially bred, so it can be raised. Moreover, it is not afraid of cold and can still live normally in the environment of 5 degrees Celsius.
