If you want the koi to grow to more than 0.5 meters, you need to raise 4mi for at least five years.

Note:

If the weather is very hot, feed less food, clean more fish tanks, and change more water. When changing water, pay attention to the water temperature. if the koi is suddenly put into cold water, it will be difficult to adapt, so it is necessary to put the water in a basin to cool for a while, so that when the Water temperature is similar to the temperature, it will be poured into the fish tank.
