? Koi and parrot fish cannot be mixed. There are two main reasons:
1. Different temperaments: Koi's temperament is relatively mild, and they generally do not take the initiative to attack other fish when they have enough food. The parrot fish is an artificially bred hybrid. Like its parent fish, it has a ferocious temperament and a strong sense of territory. When it is mixed with koi, it will initiate a fight. Although the size of Koi is relatively large, it is also possible to be bitten by parrot fish. If not treated in time, they may also die of traumatic infection.
2. Different living environment: Koi belong to native cold-water fish. Their suitable water temperature is about 20 degrees, which can promote their growth and development. Parrot fish belong to tropical fish. Their suitable water temperature is about 28 degrees. If the water temperature is too low, it will reduce their resistance and make them susceptible to disease. They were raised together and the water temperature could not be adjusted.
Koi and arowana cannot be mixed. Koi belongs to cold-water fish, which lives in alkaline water with low hardness, and the suitable water temperature is about 20 degrees. The arowana belongs to the tropical fish, lives in the weak acid waters, the suitable water temperature is about 25 degrees. By comparison, we can see that the water environment they like is quite different, especially the living water quality, acid and alkaline water can not coexist, so they can not be mixed together.
