What does the Most Expensive Japanese Koi Fish Cost?

A Short History for a Large Fish – In a pond, a Koi fish looks like a large goldfish, but there is really a rich history behind their breeding and why one can cost up to $60,000. The word Koi itself is derived from the Japanese word of Nishikigoi, which means brocaded carp. The term was meant to capture the ornamental design that is found on their bodies. The different varieties of Koi fish are determined by the patterns, scales and colors that they exhibit. The colors and patterns can range from singular colors or a combination of black, blue, cream, red, and yellow.

The Koi fish originated in Asia and some areas of Central Europe, but they were domesticated in East Asia where they were raised for food purposes. According to Chinese history of Koi fish, King Shoko of Ro gave a modified Koi fish, a black carp, to Confucius’s son as a gift. The gift was meant to represent good fortune, prosperity, and success, since the Koi fish has an energetic life force associated with it. The Chinese raised the fish originally for food and taught the Japanese to do so for impending harsh winters.

But the Japanese took the breeding of Koi fish further and began to breed them for their spectacular colors. Since the Japanese began to breed them specifically for their colors, they are given credit for the various breeds that exist today. Popularity of the Koi fish began to spread to other nations and soon Koi fish were sought after to breed as pets. And in 2014, the most expensive Koi Fish was purchased for $60,000, because she still possessed baby fish attributes but was actually eight-years old and 36-inches long.


What to Consider When Building Your Own Koi Pond.

Acquiring koi for their beauty can be addictive. But you don’t have to pay an annual salary just to own them. You can build your own Koi pond, but start small. Starting with a 500-gallon to 2000-gallon pond is ideal for a small number of koi fish. For a small size pond, keep the number of koi to under 20, because they can grow large and with this many, it will require a greater amount of aeration and filtration. Here are some important aspects to keep in mind when determining the size of your Koi pond:

  1. Besides having a minimum of 2000-gallons of water, make sure that your pond is at least 4-feet deep. This will discourage most predators, like raccoons, from entering the pond.
  2. The location of the pond should be placed in a shaded area. Also avoid placing the pond underneath trees that may possibly shed leaves, needles, fruit and nuts.
  3. Use decoys to keep Blue heron birds from eating the koi from your pond. One heron can eat as many as 100 adult sized koi in one day. Some of the best decoys are large-eyed scary looking owls with sound effects and moving parts.
  4. Although plants can enhance the beauty of the koi pond, they should be kept out of the ponds and away from the Koi. If the fish can eat them, they will. It is best to keep iris’s or lilies on plant stands and away from the Koi.

Which Koi Variety is the best to purchase?

The best variety of koi to purchase is very much dependent on the taste of the owner. Take a look at the various sizes, shapes and color patterns and determine which ones fit your budget and style. If one style or color is best suited for you, then it is the best one to purchase. However, there are many types of Koi, here is a list of the most common variety:

Asagi                           Sanke

Bekko                          Showa

Goshiki                        Tancho

Hikarimoyo                  Utsurimono

Hikari Utsuri                Koromo

Kawarimono               Hikarimuji


What are the Water Quality Expectations for a Koi Pond?

If you are serious about maintaining a Koi pond, then you should expect to labor over the water quality of the pond in order to keep the Koi fish alive and healthy. This pond is similar to a mini-ecosystem and the size of the pond can determine the quality of the water. In other words, there is a direct correlation between water quality and the size of the ponds. Larger ponds tend to have a more stable water quality environment.

Effective filtration systems will turn the water over at least two times every hour in order to be efficient. The goal is to break down nitrogen waste products given off by the fish. This biological filtration system is the most effective. Another water quality concept to consider is that water heats up in the summer months and Koi fish are cold-water fish. They require a water environment with a highly dissolved oxygen content. Water fountains and aeration devices can assist in keeping the water temperatures at the correct levels.

Another critical element to consider in water quality is the amount of food given to Koi. Uneaten food left sitting in the pond deteriorates the water quality. Therefore, following directions about the correct amount of food to be given to Koi is of high importance. Also use Koi food that is appropriate for the season.

If You Plan to Breed Koi for Showings

Some people just want to build a beautiful pond in their backyards to be admired by family members or friends that visit occasionally. Others want to enter showings for their Koi. Research what is required to breed special Koi and how to show them for their special features. There are several Koi videos on YouTube that can thoroughly explain the process.

Whatever your reason for purchasing Koi, make sure your pond is set to display the marvel that these special fish can exhibit, by following directions for water quality and feeding.
