Koi - Beautiful Japanese Carp

Ranked #3,237 in Pets & Animals, #82,453 overall

Koi is short for Nishigikoi, the Japanese word for "ornamental carp"

Koi fish have been cultivated and bred for generations in Japan to produce the brilliant colors and patterns for which they are known.  With the growing interest in water gardens in the US, many people are interested in raising and keeping koi.  This lens will help you learn the basics about koi colors and patterns and offers advice on keeping and caring for these beautiful Japanese carp. 

Color variations and names

The variation of Koi can get very complex. Here are some of the basic colors with their Japanese names. Some colors get a different name to indicate when they are body color or the color of markings on the fish. Part of what can make koi an expensive hobby is the acquisition of rare color and patterns.
  • Black - Karasu (body), Sumi (markings)
  • Blue - Ai
  • Brown - Cha
  • Gold (metallic) - Kin
  • Green - Midori
  • Grey - Sora
  • Orange - Orenji
  • Red - Aka (body color), Hi (markings)
  • Silver (metallic) - Gin
  • White - Shiro
  • Yellow - Ki

Lucky Koi Tattoos

Koi and tattoos of koi have traditional connotations of good luck to them. Some of this perception stems from ancient Asian mythology.

It is believed that a carp that can swim upstream and jump the waterfalls will be transformed into a dragon. Unlike Western dragons which are often viewed as snake-like and malevolent, Asian dragons are associated with the elements and are considered good omens and protectors.

Both koi and dragons are often found in Japanese tattooing.
