Koi fish is actually a colorful carp. Its "ancestor" originally lived in China, so it can be said that it is a native of China. When the Tang Dynasty was introduced to Japan, the Japanese propagated koi fish from generation to generation, and cultivated three classic koi fish strains: red and white, Dazheng tricolor and Showa tricolor. Life expectancy in koi fish is generally 20 to 30 years, and the longest is 40 to 50 years. It is fertile, but its constitution is worse than that of common carp.
