Blue Koi Fish for sale

How to identify blue koi

Koi read 'blue' through gray-blue skin: Asagi (netted blue back with red flanks), Shusui (its scaleless form), and Soragoi (solid sky-gray). No koi is truly cobalt — dealers advertising vivid blue fish are usually showing Asagi juveniles.

What blue koi cost

Grade Typical price (6–10″ unless noted)
Pond / garden quality $40 – $620
High grade / import up to $1,200
Show grade $3,500+

Spans several varieties — see each variety page for specifics.

Size, body conformation, and breeder line move prices more than variety alone — see the full koi price guide.

Where to buy blue koi
