How to identify your koi

Look at your fish from above in even light. Start with its main colors, then note whether the black is in small spots or wraps around the body. Check whether the skin has an overall metallic shine and whether the scales are regular, sparkling Ginrin, or reduced Doitsu scales. If a trait is hard to see, choose “Not sure” and compare the closest matches.

How can I tell Kohaku, Sanke, and Showa apart?

Kohaku has red patterns on white and no black. Sanke adds black spots to a red and white pattern. Showa has larger black markings that can wrap around the body. For other patterns, browse the complete koi classification guide.

Can this identify a koi from a photo?

This identifier asks you about visible features; it does not analyze uploaded photos. Individual koi can change color with age, and some fish combine traits that do not fit a single variety neatly. Compare the suggested fish with the photographs and detailed variety pages before deciding.
