Blue koi are indeed real! While they may not be as commonly seen as other colorful varieties of koi, such as the vibrant red and white Kohaku or the striking black and white Shiro Utsuri, blue koi do exist and can be a beautiful addition to any pond or aquarium.
There are different types of blue koi, with Asagi and Shusui being two of the most well-known varieties. Asagi, also known as “light blue,” are one of the original types of koi that were developed from the ancestral Magoi fish around 200 years ago. They have a distinct blue-gray color on their upper body, which fades into a lighter shade towards their belly. Asagi koi also typically have a red or orange pattern on their sides, known as the “net pattern,” which resembles a fishing net.
On the other hand, Shusui koi are a crossbreed between Asagi and a German mirror carp. They have a similar blue coloration on their upper body, but lack the net pattern seen in Asagi. Shusui koi often have large, prominent scales along their lateral line, which adds to their unique appearance.
It is important to note that the blue color of these koi is not as vibrant as some of the other colors seen in koi varieties. Instead, it is more of a subdued and natural-looking blue, which can be quite appealing to some koi enthusiasts. The blue coloration is a result of genetic variations and pigment distribution in the koi’s scales.
While blue koi may not be as flashy or eye-catching as some of the other koi varieties, they can still be a stunning addition to any pond or aquarium. Their simplicity and natural beauty can create a sense of tranquility and serenity. Additionally, blue koi are often prized for their unique and rare appearance, making them sought after by collectors and hobbyists.
In my personal experience, I have encountered blue koi in various koi shows and exhibitions. While they may not always stand out immediately, their subtle beauty and elegance often draw me in. The gentle blue color and intricate patterns on their scales give them a sense of mystery and intrigue. I have seen blue koi being admired and appreciated by fellow koi enthusiasts, as they are considered a true gem among koi varieties.
Blue koi are indeed real and can be a fascinating addition to any pond or aquarium. Whether you opt for the traditional Asagi with its net pattern or the unique Shusui with its prominent scales, blue koi offer a serene and natural beauty that is distinctive and captivating. While they may not be as flashy or vibrant as other koi varieties, their simplicity and rarity make them a prized choice for many koi enthusiasts.
