Koi varieties

What Kind of Koi do you have in Your Pond?

Look at your koi - what type are they?  Find your Koi in the Koi Varieties below.  Your Koi might be a mixture - but a mixture of what types?  This is the fun part about owing Koi.  Familiarize yourself with Koi Varieties below.

There are several basic lineages of koi that are accepted throughout the world. The categories are based upon markings, colors, and/or scale type. Within each category there are a number of subcategories which relate to the way in which colors, scales, or combinations of these are formed in the individual koi.

With so many koi being bred today, quite often a totally unique combination is found, which usually contains features of two or more categories. Therefore, these koi can not be placed into one of the acknowledged lineages. As they have become popular, we may find that as time goes on, some of these unique koi will eventually become consistent enough for their features to form a new category. To help you recognize the differences in your koi, we have listed the basic categories here.

You can use our Glossary of Terms to learn how to pronounce all these Koi terms.
