in a fish tank? Koi can grow up in a fish tank. Although the fish tank can raise koi, but the size of koi is relatively large, if the fish tank is slightly smaller, it is recommended to reduce the feeding density. Because Koi are usually lively and active, if the feeding density is too high, it will cause them to lack oxygen. Moreover, too high feeding density will also limit the development of Koi, such as unable to turn around and swim, and easy to fight with each other. So if you want to use a fish tank to raise big koi, it is recommended to use a larger fish tank, raise a few less, and install a filtration system in the fish tank.
in a fish tank 1. First of all, choose the right fish tank. Koi is a large ornamental fish, which has a high demand for oxygen and space. If you want to raise koi for a long time, you can choose a large fish tank, generally 1.2 meters of fish tank can raise 2 40 cm and 5 10 cm. When they grow up, & nbsp; It is recommended to replace the fish tank with a larger one.
2. Koi can be eaten and pulled. If you raise Koi in a fish tank, you need to change the water every day, and install a circulating filter system. It's better to open it 24 hours, because the filter system also has the effect of increasing oxygen.
3. Finally, stabilize the water quality. Raising koi in a fish tank is relatively easy to adjust the water quality. Koi likes weak alkaline new water, and the PH value should be controlled between 6.0 and 8.5. Although Koi fish do not require high water quality, unstable water quality will make them susceptible to illness.
