New Koi varieties are still being actively created. Koi varieties are identified by color, pattern, and scales. There may be variations within each classification such as Tancho Kohaku and Maruten Kohaku. These fish are Kohaku because they have a white body with red markings. The red, almost round, spot on the head make them a variation.
While color is theoretically unlimited, the most popular are red, white, black, yellow and blue. The following chart will help you identify 10 of the most common varieties of Koi. The first 3 varieties, kohaku, sanke, and showa, are commonly known as the “big three” and are the most popular.
