The "Sanke" must be the most popular variety in the UK and at Cascade Koi & Aquatics we have hundreds of different sanke to choose from. Also known as Taisho Sanke, or often simply abbreviated to Sanke, the taisho sanshoku is genetically a white koi with red and black markings. It is named for the time in which it was developed, the Taisho period in Japanese history. The body appears primarily white, and the colors that sit on the white should be in a spotted formation rather than banded, and there should be no black on the face.
