Koi fish are decorative varieties of carp species that are native to the United States. They can be kept in indoor or outdoor Koi tanks. They are very popular among hobbyists, and they are considered the national fish in Japan.
While the Koi fish can be confused with carp but it's in fact an element of the Cyprinidae Family. It can be used in decorative water gardens because of its huge scales and scaleless skin. https://www.kerutokoi.com/
