The Very Beginning- a Short Brief on the History of Koi Fish

Your koi fish has a very vibrant history of evolution, the mutations that resulted in different types of koi fish.  A hobby of millions today, the koi are not only a mere symbol of culture but an exploration of appeal, and varieties.  All the different types of koi have a common descendant- the solid black koi carp.  It is essential to go back in time to understand the popularity of these aquatic wonders.

The convention of the Japanese Koi fish is as accurate as it can get.  The Japanese are considered to be the very first breeders and koi hobbyists.  The black koi carp, also known as the magoi koi, was first introduced in Japan from China in the 200 BC.  Hence, opposed to the common belief, koi fish are not indigenous to Japan.  The Japanese were indeed the first to appreciate these swimming flowers as they are commonly called.  But the koi fish originally came from the Aral Sea, the Caspian Sea, and China.

The first keepers of different types of koi were Japanese rice farmers.  The fact that the koi fish was initially eaten as a local delicacy in this community might come off as a surprise to many koi keepers. The lack of cattle sources and other vast domestic channels made the koi carp fish the ultimate source of protein for Japanese farmers.  Due to genetic mutations, the rice farmers noticed the unusual color patterns on different types of koi fish.  The revelation is recorded to have taken place in the 1800s.  The Narumi Asagi koi is known to be the earliest among other types of koi that were first recognized as aquatic jewels.  The low maintenance and minimum requirements in terms of water quality, oxygen levels, and nutrition made the koi carp fish a desirable commodity for the Japanese locals.

As more years passed by, the Japanese farmers became obsessed with the different types of koi.  Thus, began the process of selective breeding, which soon led to the production of vibrant fish markings, koi fish scales, and patterns.  The earliest breed of koi was a chance happening – a red-bellied magoi koi fish.  This led to the pattern which is now popularly called the Hi marking – red koi markings.  Soon there were more than a hundred types of koi in the Ojita City Market.  As travelers from near and far lands came to the city, the recognition for vibrant koi fish color patterns gained a quick buzz.  The rice farmers soon realized that they could breed different types of koi to create more variations from the original Japanese koi fish and increase their profit and, ultimately, the demand.  With various types of koi in the market today, it can be confusing to figure out how different koi varieties came to be.

Understanding the Difference Between a Goldfish and Types of Koi

Before we get any deeper into the different types of koi fish, it is crucial to clearly understand the difference between the koi fish and their not-so-distant counterparts, the goldfish.

Here is a little table for a short glance at the difference between a koi and a goldfish:

Types of Koi Fish

Types of Koi Fish

1.    The Kohaku Koi Fish

KOHAKU e1595849900876
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 23

As an avid anime geek – the otaku, I was fascinated by the name Kohaku, almost to the point that I wanted the name for myself.  On those grounds I consider, the Kohaku Koi fish to be particularly lucky. Of course, I can’t argue that the fish is naturally entitled to its name.  Hence, the very first question that pops in your mind – what does Kohaku mean? Kohaku is the Japanese term for ‘Amber.’

Among all types of koi, the Kohaku koi fish is considered as the king amongst its brethren.  The royal koi fish was the first in the koi variety chart to have two colors on its body.  Its colors and patterns were an incredible discovery for the traditional koi rice farmers.  Even to this day, this koi among, many other types of koi, remains a fan-favorite.  Koi hobbyists love displaying and watching these koi fish exhibited in dedicated shows.  The history and culture associated with the ingenious Kohaku koi fish retain its stellar reputation even today.

A Kohaku koi fish of the top quality will have the coveted red markings or the Hi markings on its main body with a solid white color.  Often you will see a yellowish hue on its snout, a characteristic that koi keepers either don’t care about or prefer as a bonus feature.  The red markings on the Kohaku koi fish are of two major types.  The first type of Hi fish markings has a subtle purple hue.  This purple shade does not fade with the age of the Kohaku koi fish, making it an important characteristic.  But the purple addition to the fish markings has a downside; it almost blurs the edges of the hi markings. This might not be such an exciting attribute for many koi hobbyists.

The second type of fish marking seen on the Kohaku koi fish is the popular type.  The orange and red shades are harder to maintain.  As these markings become more prominent, the quality of your Kohaku koi fish increases by ten folds.  The onlookers in koi display shows prefer the second type of fish markings on the Kohaku koi to be more desirable.

The white basal body helps the red koi fish color patterns to stand out even more on the Kohaku koi fish.   The dark red patterns present on the head are different from those present on the main body. The red markings on the koi head are known as ‘bongiri.’  While the Kohaku koi with devoid of head markings are known as ‘boze.’  The balance of Hi markings on the overall body of koi fish imparts a sense of tranquility as it swirls in the pond with other types of koi.  As koi fish enthusiasts say- true beauty lies in simplicity.  Due to the high demand, you will rarely see a Kohaku koi fish for sale at a fish specialty store; however, if you do, do not miss the opportunity.

The female Kohaku koi fish names S Legend is the most expensive koi fish for sale ever.  It was bred by Kentaro Sakai, an expert in breeds of koi.  The bidding took place in Taiwan, where the koi fish was sold for a total of £1.4 million.  Among the other types of koi, the Kohaku koi carp is one of the most coveted ones.

2.    The Asagi koi fish

Asagi e1595849987950
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 24

Along with the kohaku koi, asagi koi fish is also one of the ancient types of koi.  The asagi koi was considered a local delicacy among the Japanese farmers of the old days until they realized its true beauty and potential.  If you are a member of a group of koi hobbyist, you are sure to come across at least one asagi koi fish in their ponds.  The asagi koi fry is the exact visual replica of the adult asagi koi. They have the typical diamond-like scale patterns, the red-hi- fish markings. The asagi koi is undoubtedly not a metallic koi, meaning they do not have the classic sheen on their bodies.  The hi koi markings are prominent on the tails, asagi belly, and its gill plates.  Seldom do the red fish markings appear on the dorsal fin in the later stages of the asagi koi’s life!

Adding to the list of different types of koi is a variant of the conventional asagi koi fish- the taki asagi. Due to the striking similarity, the koi variety identification can get quite tricky for a beginner koi keeper.  A taki asagi has a supplementary scale formation between the red and blue fish markings.  The stunning and mysterious red eyes are a desirable feature that determines the highest quality of asagi koi fish.   The highest grade version of asagi koi fish has a spotless white head with subtle grey undertones.  In case the asagi koi develops any kind of pigmentation on its koi head, it is called the menkaburi koi.  If you see an asagi koi for sale, with the most vibrant blue koi scales, you will most certainly get a bang for the bucks you spend.  Such features on an asagi koi fish are highly coveted among fish hobbyists.

3.    The Taisho Sanke Koi Fish

Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 25

One of the more popular types of koi is the taisho sanke or the taisho sanshoku koi fish.  This fish, with its red black-white patterns, was first bred around 1868 to 1912.  A fifteen-year-old taisho sanke was added to the koi varieties chart.  The fish’s overall body is subtly black, which is disturbed by the red and white fish markings.  The taisho sanke shares a lot of similarity with the kohaku koi fish, except for the extra black markings called the ‘Sumi.’  This koi fish was first bred in the reign of the Taisho Emperor, hence the name. The first breeder of the taisho sanke was Gonzo Hiroi.

Another koi sharing a lot of similarity with the taisho sanke is the showa koi fish.  The taisho sanke koi fish is another non-metallic variety in the types of koi fish chart.  The taisho sanke has a solid white body along with red fish markings, which are more inclined towards an orange hue called the beni or the sanke.

4.    The Bekko Koi Fish

BEKKO e1595849975455
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 26

The bekko koi is a non-metallic black and white koi fish with Sumi or black spots on the entirety of its body.  The bekko fish has three different color variants – white, yellow, and red.  The white bekko is called the Shiro bekko supplemented with black splotches.  The aka bekko is a particularly red koi with black sports while the ki bekko is the yellow variety with black spots.  Among the three variants, the ki bekko or the yellow koi is the rarest variety.

The placement of the black koi fish markings called the Sumi is the strongest attribute for determining the highest quality of the bekko koi.  The koi head should be spotless and solid white for a better visual balance.  If you are a beginner koi hobbyist, the bekko koi will be your  first addition to the pond among the other types of koi.

5.    The Ginrin Koi Fish

Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 27

The ginrin koi is another addition to your different types of koi chart. The ginrin koi has a distinct metallic sheen that is one of its most attractive features.  Mr. Kamidera from Hiroshima is known to be the very first ginrin koi breeder.  The Daiya girin koi fish is an exciting variety among other types of koi.  Daiya in Japanese means’ diamond,’ which is perhaps a correct association to the ginrin koi variety. Kin is gold in Japanese, while gin is the Japanese word for silver, and rin means koi scales.  Hence, the formation of the complete word kin-gin-rin koi explains the full context of this koi fish.

Pearl ginrin koi is another sub-type that catches the attention of koi fish hobbyists.  While the Daiya ginrin is known for fish markings, the pearl ginrin is known for its shine.  Due to the limited production of the fish variety is a common reason why you wouldn’t see the ginrin koi as often at a koi vendor’s shop.  Typically, patterns and fish markings are not the more prominent considerations for ginrin koi fish.  The koi scales are the striking features that determine the grade of the ginrin koi fish.

6.    The Doitsu Koi Fish

DOITSU e1595849958430
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 28

Among the different types of koi, the doitsu koi fish is known as the mainstream belle with no scales. The koi fish hobbyist is divided into the group in the context of the doitsu koi fish.  The first half adore their solid body that looks especially enchanting in the pretty koi pictures.  In comparison, others do not find the koi worthy because the doitsu koi is devoid of koi fish scales hence the metallic sheen.  Going beyond their opinions, we find the doitsu koi fish an exciting addition to any koi pond.  Much like the Kohaku and bekko koi fish, the doitsu koi also has a peculiar history.  They, too, were considered as a local German delicacy.  No, you didn’t read that wrong, unlike the other types of koi, the country of origin for the doitsu koi is Germany.  They were especially desirable among German chefs because they were easy to prepare.  Sailing along, in case you are wondering- what does doitsu mean?  The word doitsu is derived from the German word- ‘Deutsche.’ Invariably, Doitsu is the Japanese word for Germany or a particular German deity of the religion called Doitsuism.

It was Mr. Kichigoro Akiyama, an expert fish breeder, who came with the idea of crossing the doitsu koi that is devoid of koi scales with the asagi koi that is infamous for its diamond-like scale patterns. Selective breeding of the doitsu koi and the asagi koi led to another addition to types of koi chart, called the shusui.   Both the types of koi have blue koi scales and red-hi- fish markings on their bodies. If you come across a doitsu koi for sale at your local store, it’s probably the shusui variant because of how commonly they are bred.

7.    The Goshiki Koi Fish

GOSHIKI e1595849936953
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 29

The goshiki koi is an exciting addition to the common types of koi chart.  It is bred between the asagi and the taisho Sanke koi varieties.  Goshiki koi are known for their pentagon koi fish color patterns. Not too long ago, the goshiki koi were identified as a subtype of the kawarimono koi group. However, due to their popularity and peculiar koi color patterns, they were soon given a separate place in the types of koi inventory.  The goshiki koi are often called peacock jewels in a pond due to the five colors present on the central bodies.  Typically, the base color of the main body is white, which is then disturbed by different fish markings and patterns.  The fins are often free of any spots and have a solid white color.

The netting pattern on the koi, and the hi markings should be consistent for classifying it as a high-grade variety.  Older goshiki koi devoid of any coaxed mutations had dark red patterns and heavy reticulations on the koi scales.  As this original variant of the goshiki koi ages, the body gets even darker and exhibits vibrant contrasting red-hi fish markings. 

8.    The Hirenaga Koi Fish

The peculiar history of the Hirenaga koi can be traced back to the era of the Japanese emperor – Akihito.  The long-fin carp was underrated when the emperor first laid his eyes on the koi fish during his visit to Indonesia.  It dawned upon him that it would be interesting to see the Indonesian hirenaga koi cross-bred with the different types of Japanese koi fish.  He brought his idea to the experts on various breeds of koi at the Saitama Inland Water Fisheries Experimentation unit.  The koi breeder there created their first hirenaga koi variant in 1991.

Considering the traction it received during the reign of Japanese emperor Akihito; the Hirenaga koi failed to gain further popularity among Japanese koi enthusiasts.  However, it quickly became the center of attraction among international koi hobbyists.  The large scale difference in the prevalence of the hirenaga koi fish in Japan and internationally can be attributed to the cultural consensus that has been quite prevalent ever since.  It must have been the imperfection or the unbalanced fish markings on the hirenaga koi fish that must have deterred the Japanese from accepting the long-tailed orange koi carp as their own.

9.    The Goromo Koi Fish

Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 30

The goromo koi fish receives a relatively more significant adoration among other types of koi, both in Japan and internationally.  The goromo koi is cross bred fish, mainly known for its original koi scale patterns.  If hi fish markings are characteristics with dark red patterns on the edges, this would become the Ai goromo variety.  The orange white and black fish, where the black koi markings appear centrally on the hi fish markings that would classify as the Sumi goromo koi.  The Budo Goromo, on the other hand, has black and red patterns overlapping with each other to create an almost purple koi fish.

These koi patterns make it easy to classify the goromo koi into three different variants- the Ai goromo, Sumi goromo, and the budo goromo.  Among the three types of koi, the Ai goromo is the most preferred koi fish.  Spotting the features that will make the goromo koi a definite winner, is particularly hard even for an expert in breeds of koi.  If you are lucky, your goromo will grow into a real jewel.  On the contrary, if you spot an inconsistency in the koi markings, your goromo koi will turn into a different variant in the koi varieties chart called the Goshiki koi.

10.  The Ai Goromo Koi Fish

AI GOROMO e1595849994817
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 31

Ai goromo koi has red and white patterns on its body. But the most interesting feature is apparent in its koi scales. There is a slight darkening of the koi scales edges in a reticulate manner. This is confirmed to be the remnant trait from its ancestor, the asagi koi fish. When the Ai goromo koi is young, the darker edges on the koi scales are slightly faint. However, as the koi fish ages, these patterns become more prominent. If you see excess sumi-black spots on the ai goromo koi, the adult koi will surely have unbalanced fish markings. An ai goromo koi of the highest quality will have the dark red patterns – hi, evenly distributed across its body, expects the koi fish head.

11.  The Budo Goromo Koi Fish

Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 32

The Budo goromo koi shares several similarities in terms of features with its close cousin- the ai goromo koi. For identification, there is one major factor that varies by a large margin between the two goromo koi.

The Budo goromo can be safely attributed as a purple koi fish because dark red patterns on the edges of the koi scales mix with the blue markings. This leads to an almost enchanting purple hue. The budo goromo shares a pearl white solid body with the ai goromo koi. However, if the black spots or the sumi migrate to the main body, the budo goromo is more likely to turn into a goshiki koi, which is not as desirable for koi hobbyists.

12.  The Sumi Goromo Koi Fish

SUMI GOROMO e1595849846237
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 33

The sumi goromo is a black and white koi fish, which is rather rare when compared to the ai goromo and the budo goromo. The word sumi refers to black in japan, which accurately explains the dark black fish markings that develop on the hi markings. The sumi goromo is an accidental breed, a mutation of the goshiki koi. However, due to its interesting color patterns that are often well-balanced, the sumi goromo koi is considered a prominent addition to the different types of koi.                                                                                     

13.  The Kawarimono Koi Fish

Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 34

The kawarinmono classification encompasses several types of koi, particularly those that do not have a specific trait to be considered as separate breeds of koi.  There are a total of 14 different types of koi fish within the kawarimono category.  The Beni Kumonryu, chagoi koi fish, soragoi koi, ginrin ochiba Shigure, Karasu, Kumonryu, matsukawabakke, golden crown, kawarigoi, Shiro koi, midorigoi, kigoi, Karasu, hajiro are the 14 varieties under the Kawarimono koi type.  These varieties are often understood as less popular accessory koi fishes; however, that is simply a misconception among those who don’t know better.

The myriads of different types of koi within this koi varieties chart, make the group genuinely unique. The significant features of these koi fish are striking color patterns, non-metallic body, dark red patterns, consistent fish markings, etc.  These features should remain unfaded and distinct for a koi fish to be considered of the highest quality.

14.  The Kikoryu Koi Fish

The kikoryu koi fish is considered a prominent category in the type of koi; it is a variant of the Doitsu koi fish. The kikoryu koi fish is a metallic black and white butterfly koi.  The koi fish varies in terms of being often having a dorsal line of singular koi scales.  As a beginner koi hobbyist, you might confuse the kikoryu koi variety as a ginrin koi fish.  Kikoryu was first bred as from kumonryu and platinum ogon.  If you are a kumonryu enthusiast, you will appreciate the kikoryu koi fish better.  Koi fish vendors get ecstatic when they find a kikoryu koi fish on sale because two kikoryu koi are not similar.

The designs on the kikoryu never lead to similar patterns.  The mutations are always as unique as the sheen enhances as the fish ages.  Deviating from the standard black and white koi fish, kikoryu koi come in various fish markings and koi scale patterns when crossed between ogon and the kumonryu. This black and white butterfly koi fish is a bundle of surprises as the patterns shift and alter proportionally to the koi fish’s growth.

15.  The Shusui Koi Fish

SHUSUI e1595849864433
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 35

The first shusui koi fish was bred in 1910 between an Asagi koi fish and a mirror koi carp.  The result of the koi breeding was a shusui koi with Asagi koi colors and the scale lining on its back.  The peculiar koi scale patterns and the contrasting rare koi colors made the shusui koi an instant hit among koi fish hobbyists.  Much like the typical mirror carp, the shusui has a singular lining of koi fish scales on the dorsum bringing it closer to its carp ancestor. The koi scales begin from the shusui koi fish head extending up to the tail.

The blue, orange fish coloring is an unusual sight because of how contrasting the colors on the shusui fish seem when it swirls in the water.  Despite the strange color patterns, the scales take the prize as the most attractive layout on the koi fish body.  The shusui koi is relatively more eye-catching when compared to the other types of koi.  If you see shusui koi for sale, make sure you grab the opportunity to dazzle your koi collection.

16.  The Showa Koi Fish

SHOWA e1595849871766
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 36

The showa koi fish is a popular choice among outdoor koi pond owners. The Showa koi also alternatively called the Nishikigoi or the ornamented Japanese koi carp.  The showa koi fish is highly prized due to the well-balanced fish markings and the dark red patterns.  The orange white and black fish are categorized as Sumi black koi having prominent hi (red) and Shiro (white) fish markings.

The first show koi fish was produced in the era of the Japanese emperor –Showa.  The parents of the first showa to be ever bred were two different types of koi –  Kohaku koi fish and a Shiro Utsuri.  Due to the expansion of the Shiro or white fish marking, it has become quite difficult to discern a showa koi from the sanke variety.  A high quality showa fish has well-balanced patterns and sharp edges between two color patterns.  The showa having a black (Sumi) ridge across its face is undoubtedly a cool koi fish.

17.  The Tancho Koi Fish

TANCHO e1595849823874
Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 37

The tancho koi fish is certainly not a spotted koi except for a prominent hi fish markings on the koi head.   It is safe to say that a tancho koi fish is a Kohaku koi minus the markings on its body.  The tancho koi are bred from different types of koi, but more particularly, the go sanke varieties are used for tancho koi breeding.  Rare tancho koi is seldom occurring, and among all kinds of koi breeding candidates, the tancho koi fish never deviates from the characteristic koi head hi marking.

The dark red pattern on the koi head is present centrally between the eyes of the tancho koi.  The symmetrical fish markings and the solid white base body are two critical characteristics to consider a particular tancho koi as a high-grade fish.  The Sumi markings of a tancho sanke are similar to the bekko koi fish. And the black Sumi spots on the tancho showa resemble the Shiro utsuri variant of the koi fish.

18.  The Utsurimono Koi Fish

Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 38

The utsurimono koi fish is another prominent addition to the different types of koi fish.  Its ancestor is the stunning hybrid showa sanshoku koi fish.  The black koi fish is categorized further depending on the types of fish markings present on its overall body.  The Shiro utsuri, the hi utsuri, and the ki utsuri are the popular varieties of the Utsurimono koi fish.  The black Sumi marking covers the majority of the koi head and the pectoral fins.  Among three types of utsurimono koi, the ki utsuri koi are the rarest and also the oldest.

19.  The Ogon Koi Fish

The word ogon means ‘golden’ in Japanese.  The ogon koi fish is the most prominent koi, among other types of koi.  The ogon koi is also one of the earliest in the koi varieties chart.  They have been considered a visual commodity among koi hobbyist ever since the 1940s.  The Aoki family of japan is credited to the first breeder of the ogon koi fish.  The kin matsuba was the first breed between a Matsuba koi and platinum ogon.  The robust metallic body glistened as the ogon koi swirls in clear water is a very attractive visual for koi hobbyists.  Today there a variety of ogon koi breeds, in which the cream-colored variant is the rarest.  The most popular types of koi in the ogon category is the Yamabuki ogon with bright yellow sheen.  The purachina ogon or the platinum ogon is the second in terms of popularity.

20.  The Hikarimoyo Koi Fish

Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 39

A koi fish displaying two or more colors on a metallic body is classified under the Hikarimoyo types of fish. Hence, the ogon koi, kin matsuba koi, and the gin matsuba can safely fall under the Hikarimoyo classification. The dark skin with striking color patterns is quite apparent even when the koi is not an adult. The dark ridges on the koi fish head running between the eyes and the nose is a truly enchanting feature that will make heads turn. The Hikarimoyo is a rather vast category encompassing several types of koi. The major breeds of koi that are the jewel of the Hikarimoyo koi variety are the Hariwake, the dual-colored koi with a solid platinum body. The other candidate who makes up to the top of the list is the harikawe matsuba, which has the same reticulation as a typical matsuba koi.

21.  The Kujaku Koi Fish

Complete Guide to Different Types of Koi Fish - (22 Major Koi Varieties) 40

The kujaku koi is an ogon koi fish but some features similar to the kohaku koi, particularly the net-like reticulation on its dorsum. The reticulation is overlaid with orange or red fish markings of that of the kohaku koi fish. The kujaku is a hybrid koi between a gokishi koi and a hikarimuji. The kujaku koi was first bred in the 1960s by an expert in breeds of koi- Mr. Nishi Hirasawa. Initially, the kujaku koi was categorized under the hikarimoyo types of koi. The amount of appreciation that the kujaku koi received, is considered a sperate entity in the types of koi list.
