Asagi (浅葱 “pale blue-green, indigo”, sometimes written 浅黄 “light yellow”) is one of the oldest types of koi. It was developed in Japan about 160 years ago from the Asagi Magoi, a common black carp (Magoi) with a genetic colour mutation.
Asagi koi are predominantly blue (ai, 藍 "indigo") and red/orange (aka or hi) fish with some white (shiro). Occasionally the blue may be grey and the red may be yellow. The blue should be a consistent shade over the body of the fish but individual scales should be darker in the middle and have a paler edge, resulting in a netting pattern. The red should be rich and bright with a good, crisp edge. White, if present, should be clear and unblemished with a porcelain-like sheen. Asagi koi usually have a blue back, red sides and a white belly. The head and fins are usually a paler shade of blue/grey or white with red on the cheeks and at the base of the fins. The blue tends to darken with age.Konjo Asagi

Disclaimer #2: When I say features are ‘desirable’, ‘preferred’ or ‘should be’ a certain way I’m just talking about show standards and what breeders look for. The most beautiful koi is one that is happy, healthy and loved, regardless of its markings.Koi Key: Patterns and Colours Koi Key: Body and Scale Types Koi ID Help
