What Are Koi?

Koi were originally called "irogoi" (色鯉, colored carp), hanagoi (花鯉, flower carp), and "moyougoi" (模様鯉, patterned carp) in Japanese.
They started to be called Nishikigoi (錦鯉, brocade carp) because of their luxurious designs reminiscent of a brocade.
The Japanese brocade shown at 0:14 in the documentary video is a Japanese traditional silk fabric made by weaving variously colored threads.

Koi were originally eaten as a food, then, one day, a unique fish with beautiful patterns appeared.
There are many kinds of koi, such as red and white and tri-colored koi with red, white, and black.
In addition to the Taisho Sanshoku (tri-color) and the Showa Sanshoku, there are some unusually colored ones, such as light yellow, autumn Green, tortoise shell patterned koi, reflective koi, five Colored koi, and gold and Peacock koi as well.
