The best viewing angle of Koi is overlooking, if the fish tank is used to raise, the viewing angle will become level, so the viewing effect is not the best, so Koi is not suitable for raising in the fish tank. Moreover, the size of Koi is large, and its adult body length can reach 1-1.5 meters, so it is easy to have insufficient space to raise it in a fish tank. In addition, Koi carp has a high demand for oxygen, and the water in the tank is small, so it is easy to have insufficient dissolved oxygen when feeding.
1. why Koi is not suitable for fish
tank Koi is not suitable for fish tank for many reasons, first of all, ornamental is not strong, Koi belongs to ornamental fish, the best viewing angle is overlooking, because the back of Koi is colorful, and the color and pattern are more beautiful. If the koi is kept in a fish tank, the viewing angle becomes level, but the viewing angle of the koi is not strong, so it is not suitable to be kept in a fish tank.
Secondly, there is a lack of space. Koi are large and their adult body length is about 1 meter. Although the length of the fish tank used in the family can reach more than 1 meter, the width is generally not enough, so the use of the fish tank may limit their growth.
Finally, Koi has a large demand for oxygen. The water in the fish tank is relatively small, so the dissolved oxygen in the water will not be too much. Raising Koi in the fish tank will cause the problem of hypoxia. As mentioned
above, the best viewing angle of Koi is overlooking, so they are more suitable for raising in the ground pond or lotus pond. This can not only enhance their ornamental, but also give them enough space to move, so that they can grow and develop better. If there is no fish pond or pond, it can also be raised in a round tank. The more common koi tanks are yellow sand tank, Tianjin mud tank, Yixing pottery tank and Jiangxi porcelain tank, but this tank can only hold 60 liters of water, which is suitable for raising koi seedlings.
