What is the differences between koi and longfin, butterfly, or dragon koi?
First let us discuss: longfin, butterfly, or dragon koi. They are different names for koi with extensively longer fins. They are said to have originated from Thailand. Whereas the Japanese versions have shorter fins and were considered “standard” koi by the Japanese. For many years longfin koi were shunned by Japanese breaders and the koi associations. The popularity of longfin koi in the United States has started to influence change in those opinions. Some Japanese koi breeders are developing longfin, butterfly or dragon koi. The Associated Koi Clubs of America has people certified by AKCA to be koi judges. They are dealing with specifications on how to judge longfin koi. Many Koi Shows have various awards for “standard” koi, but currently only have one judging option of “longfin” for all of the color combinations and sizes. If you wish to learn more about Koi there is another non-profit club in the Greater Phoenix area where Koi is their focus: Valley of the Sun Koi Club, Inc.
