Koi Varieties - Koi Breeders Direct

Platinum Ogon, or Purachina, are white koi whose body shines with the same luster as the precious metal. These first appeared in 1963, probably from out crossing Kigoi with the grayish-silver Nezu (short for the Japanese word for rat, nezumi) Ogon - which remains a variety in its own right.

At about the same time, the Cream Ogon became popular. This is a metallic koi, midway between a Purachina and a Yamabuki Ogon. Examples of this breed are very rare.
