The koi fish keeping hobby is a very rewarding way to spend time, but is not the best low cost hobby. There are many risks and costs to maintain a backyard pond.

How much is a koi fish?

Koi fish prices range from $10 for a 5” juvenile to over $50,000 for champion level quality. 

The price of koi fish can vary greatly depending on a number of factors such as their genetic lineage, size, coloration pattern, breed, and whether they are purchased in bulk or individually, among other factors. Different varieties range in cost according to rarity and difficulty of breeding, as well. For example, an imported Japanese  koi can be worth $100 – $1,500 on average.

What are the most expensive koi?

The most expensive koi fish are better looking and are potential koi show winners. As they say, beauty is in the eye of the beholder, so the cost of a koi fish can vary greatly, depending on who you ask.

Some can be so precious to the owner, they are not for sale, or would be over $100,000.

What is the most expensive koi sale?

The most expensive koi purchase in recorded history is assumed to be S Legend, a Kohaku variety that brought in a whopping $1.8 million (203 million Yen) in October 2018. Kohaku is generally the most valuable koi fish variety.

Miss Yingying, a koi enthusiast and collector, bought the female 39-inch koi from the breeder Kentaro Sakai, after an intense bidding war at his fish farm.

This pictured koi is a show quality koi and a beautiful example of a 3 step Kohaku. It has wonderful body conformation, thick shoulders and perfectly white tail, fins, and nose. The colors on the face and head also give it a fierce look. When viewing a fish of this caliber, it becomes very obvious how large a difference there is between koi.

For the purposes of this article, we are referring to Japanese bred koi, there are many other types of domestic or imported koi fish, but the best priced koi will always have been born in Japan and have a direct lineage to previous high quality koi.

Buying healthy, high-quality koi is an investment, they are living creatures, and should not be taken lightly, so it is important to do your research to discover what koi are best suited for you, your environment, and your budget. Prepare your pond and test out smaller fish while you practice and get better. Losing koi stinks, but losing expensive, high quality koi, hurts even more!

What factors affect koi fish cost?

When it comes to the cost of koi fish, there are many factors to consider. Here are the top considerations on koi prices.

1. Bloodline, beauty (body shape, quality, and pattern), variety, and rarity (of pattern or variety) are the primary factors that determine the price of a koi. Size directly correlates with cost, as larger fish tend to cost more than smaller ones.

2. Age also impacts price of koi fish, as adult koi two to four years old are larger and longer, thus fetching a higher price. For example, Tosai Koi are koi that are just one year old and Tategoi Koi are koi at any age that have great potential The younger the fish, the smaller the price may be. You may consider buying koi when they are small and young and rolling the dice to which you might be pleasantly surprised, or you can consider purchasing larger koi  that the patterns and colors are already visible for your liking.

3. Size matters, Kodama Koi Farm offers koi of all sizes. A jumbo koi is a large fish that is typically longer than 24 inches (61 cm) and can weigh up to 40 pounds (18 kg). They are typically found in high-end koi ponds and are highly sought after by koi enthusiasts. Jumbo koi feature vibrant colors and patterns, with some varieties featuring butterfly fins and intricate designs.

4. Shipping is an important factor to consider. Depending on where you are located the shipping costs can vary greatly. Our Japanese koi are imported from Japan and are all safely shipped out after a quarantine period from our location in Hawaii. If you are outside of the USA, you may not be able to have koi shipped to you from USA companies, however, there are dealers that specialize in your region. All koi here are tested for KHV so you can rest assured your koi will not have specific diseases before delivery.

5. Overall perceived beauty. Ultimately, buy koi fish is like purchasing a work of art. What you think is the most beautiful koi, is going to be the best for you personally, even if it is not a champion koi. Just like a cute mutt for a puppy can be even cuter than a purebred. When planning to compete in koi shows, it is a whole different conversation on price, since there are other factors to consider.

Koi are also classified based on their quality: pond quality and show quality. We’ll detail the difference between these below.

What is the difference between a show-quality koi and a pond-quality koi?

The difference between show quality and pond quality depends on the beauty of the Koi.

Show quality Koi has a great body, excellent quality and attractive pattern. Show quality are the Koi that are ready to compete or have potential to compete because they have those features. The cost of show koi depends on the beauty and the potential. The most popular show koi are Kohaku, Sanke and Showa because they are usually the ones to win grand champions.

Pond-quality Koi, regardless of the bloodline, are the Koi that are beautiful but do not meet the conditions to compete. Just because they are not fit for competition standards, doesn’t mean they are any less desirable. They’re still beautiful additions to any home pond. We sell high quality koi from Japan and all sold from our farm are considered pond quality.
