Koi is a diverse variety of ornamental fish. There are many kinds of koi, and each kind has its unique characteristics and ornamental value. Here are some common types of koi:
Nine-patterned dragon koi: This kind of koi is characterized by its changing jet-black color and the surging appearance of dark clouds. Its ink patterns have distinct edges, and the white patches are in the basic form of lightning patterns, giving people an imposing manner of "a dragon ascending to the sky" as a whole. Nine-patterned dragon koi is mainly distributed in China and Japan.
Gold and silver scale koi: This kind of koi is covered with golden or silver scales all over, shining brightly. If the scales are on the red markings, they will present a golden luster and are called gold scale koi; on a white or black background, they will present a silver luster and are called silver scale koi.
Red and white koi: Red and white koi is characterized by its pure white background and bright red markings. The red markings are based on purple and are distributed on the edges of the dorsal fin and anal fin. This kind of koi has a long lifespan, with an average of about 70 years. It is originally from Japan, but can also be seen in China.
Tancho koi: Tancho koi is snow-white all over, with only a red round spot in the middle of the top of the head. When swimming, it is like a white dragon turning over the river. When still, it is like a red sun lying on the water. This kind of koi is considered to bring prosperity in career and official luck in feng shui, so it also has the laudatory name of "good fortune arrives".
Taisho sanke koi: Taisho sanke koi is cultivated on the basis of red and white koi, with red, white, and black three colors with ink spots. This kind of koi has existed since the Taisho era in Japan in the early 20th century, so it is named Taisho sanke.
Bekko koi: Bekko koi presents black spots on different backgrounds of white, crimson, and golden, which is also the reason for its name. This kind of koi has a unique appearance and high ornamental value.
Showa sanke koi: Showa sanke koi was cultivated in the Showa era in Japan in the 1930s, so it is named. This kind of koi's appearance combines red, white, and black three colors, with rich colors and extremely high ornamental value.
These koi varieties not only have their own characteristics in appearance, but also have their own merits in breeding and ornamental value, suitable for the needs of different enthusiasts.
