Many Koi Fish Varieties
Did you know there are dozens of named types of koi? Some of these koi fish varieties are unique and named, but the type you would find in a store are typically just a mixed breed of koi fish.
If you're looking for a purebred koi fish, you'll need to contact a specialty koi fish breeder. Another way to think about is this: if you walk into a koi fish store and see all the koi in a tank together like in the video below, they're probably not a purebred koi variety.
