Butterfly Koi have gained immense popularity in the US since their introduction nearly 35 years ago. And it all started right here at Blue Ridge Koi.
Since the 1950s, Blue Ridge Fish Hatchery had grown into the nation’s leading producer of Koi and Goldfish. Like any growing business, we constantly searched for ways to expand our product line. An opportunity seemed to present itself when we noticed an ad offering long-finned Koi for sale.

We placed an order and waited anxiously for our new Koi to arrive. Initially, we were quite disappointed. The dozen fish in the box were not Koi at all, but appeared to be wild carp with long, flowing fins and a simple gray or brown color
We have since learned that these fish came from a feral population of carp that inhabited the ditches and canals of Indonesia. Seemingly, no one knows the origin of these fish, their exact species, or how they acquired their long fins.
Although they were interesting, we did not see any commercial value in these fish. Frankly, they were ugly. However, we decided to place them in a protected pond and grow them out to maturity. What a fateful decision that turned out to be.
Two years later, we had only four of the original fish left. Each of them had grown tremendously, now weighing between six and eight pounds each. We were still convinced that there was no commercial value in their current state. But what would happen if we crossbred them with our existing Koi stock? Could we transfer their fin traits to produce colorful Koi with long and flowing fins? We decided it was worth a try. Two female long-finned carp were placed into a two-acre production pond with two of our best Gin Rin Ogon male Koi.
We eagerly awaited the spawning and subsequent hatching of the hybrid fry. The offspring proved to be very strong and grew rapidly. However, at only a few inches in length, they looked mostly like wild carp with long fins. Not the results we were hoping for. Amid our disappointment, we discussed culling the entire pond and putting it to better use. Ultimately, we decided to allow the hybrid fish to remain in the pond until the end of the growing season, another fateful decision.
As they grew larger, some very interesting fish began to appear in the mix. A small percentage of them turned into beautiful fish with bright, vibrant color and long, flowing fins. Some of them had long fins and a luminous, metallic glow that could be described as “pearlescent.”
While admiring them in a small show pool one day, Randy LeFever (former co-owner and president of Blue Ridge Koi) exclaimed, “They remind me of butterflies.” We realized that we had some diamonds in the rough and a great name with which to market them.

We were ecstatic at the commercial possibilities of this new type of Koi. However, we were also worried that these hybrids may be sterile, as is often the case when crossbreeding two species. We would have to wait two years to find out. The highest quality fish were selected from the initial spawning and grown to maturity.
Once they reached sexual maturity, the very best of the first-generation hybrids were stocked together in a breeding pond. The pond was monitored very closely, and an excellent spawn and hatch resulted. Our two years wait had paid off. They weren’t sterile!
The fry grew very rapidly despite being rather crowded. We noticed that they had hybrid vigor, which often results when crossbreeding two species. However, at about an inch in length, the prospects did not look great for these fry. Just like the initial crossbreeding, all of these offspring were quite ugly, with a dirty brown or gray color that resembled wild carp. Learning from our first spawn, we gave them time to grow and mature.
Sure enough, by the end of the fall, when they had reached 3 to 5 inches in length, some beautiful Butterfly Koi began to appear in the mix. We were finally convinced that we had a new product on our hands.
With further selective breeding, we went on to produce Butterfly Koi that, unlike traditional, standard fin Koi, are beautiful when viewed from the sides as well as the top. They swim with such grace and regal bearing, making Butterfly Koi a truly beautiful pond fish. Additionally, they are stronger, hardier, and more disease-resistant than either common Goldfish or standard fin Koi due to their hybrid vigor.
One-year-old Showa Butterfly Koi. Showa is a highly sought-after butterfly variety initially developed right here at Blue Ridge.
We later learned that a very fine and beautiful strain of long-finned Koi had been developed in Japan. The Japanese had used the same Indonesian long-fin carp to develop their long-fin Koi or “water dragons,” as they are known in Japan. They likely began their hybridizing program before we did, but that remains up for debate.
We were able to obtain some of the Japanese long-fin Koi and crossbreed them with our Butterfly Koi. The resulting offspring displayed some beautiful new colors and patterns that had never been seen in Koi before. The metallic underlay in the skin and fins is carried to the extreme. Also, the gin rin (sparkling diamond scales) displays more prominently than in standard fin Koi.
Since our initial crop of Butterfly Koi was hatched nearly 40 years ago, we have selectively bred the butterfly fins into nearly every variety of Koi. Although Blue Ridge’s breeding program has ended, the legacy of Blue Ridge Butterfly Koi continues to live on. The vast majority of Butterfly Koi seen in the US today can be traced back to bloodlines initially developed at Blue Ridge. The Aquamade Butterfly Koi breeder that is now supplying Blue Ridge even acquired some Blue Ridge Butterfly Koi for his broodstock!
