What Is a Chagoi Koi Fish?

The Chagoi fish is a popular aquarium fish and is also kept for food in some parts of the world. The Chagoi koi has a light brown body with dark spots and a white belly. Chagoi are the most common breed of koi fish, having been developed in the Taisho Era (1912-1926). It is a dark brown or greenish brown with prominent scales, which are not as distinct as those on the common Black Carp(Magoi).

The basic Chagoi is an ideal choice for anyone looking for a fish with personality. You'll find that this pet is probably more intelligent than the others in your pond. It is credited with being the most sociable of the koi categories because it is the most aggressive at feeding time and frequently the first fish to be hand-tamed.

So Chagoi is frequently purchased as a solo entity to tame the rest of a group, rather than for its color. It's not difficult to get the rest of the fish once one begins to eat from your hand. A Chagoi koi can reach a length of 2 feet and a weight of up to 10 pounds.

The Chagoi is a brown koi, but not all brown koi are Chagoi. There are numerous sorts of quality, and certain characteristics may be discovered.

Physical Characteristics

  • The Chagoi koi are a very large variety of fish. When the koi are tiny and still developing, you can see that they're powerful and eat a lot.
  • They're bigger than other koi of comparable age, and they may reach a length of up to 40 inches as adults!

  • Chagoi koi fish have bodies that are thick and blocky. Their heads are broad, so they don't resemble slender, streamlined koi fish.

  • The base of the tail (knuckle) should be thick and fleshy.

  • Their pectoral fins and dorsal fin are not split.

  • Chagoi Koi have enormous paddle-shaped pectorals and huge wide heads.

  • The eyes of a Chagoi should be bright and active, with crystal-clear corneas.

  • Darker brown or blackish Chagoi are considered low grade and normally culled from the population.

Types of Chagoi Koi Fish

Types of Chagoi Koi Fish

When you go to a koi farm, the brown koi are everywhere. Many Chagoi are brown, but not all brown koi are Chagoi. There are many different patterns and colors of brown that this koi variety can exhibit. Chagoi koi can be categorized by their patterns and colors.

On the Basis of Patterns

Chagoi koi come in a variety of patterns that offer interest to your pond. While each koi is distinct, these varieties stand out in their own way.

Chagoi fish have two patterns: with fukurin and without fukurin.

With Fukurin

It's the Chagoi with Fukurin (foo'kure-in) when each scale is highlighted with a black edging. It provides the fish a "fishnet" design over the brown coloration.

This may be missing in scaleless Chagois and some of the Chagoi hues. It's up to you which type you choose.

Without Fukurin

Chagoi doesn't have fukurin in certain hues. They're still Chagoi koi that are in good health. They may have scales in proper alignment, as long as they're healthy. The Japanese term fukurin refers only to the color of the scales' edges.

If the scales are "lined up," that means they're in better condition. The more "aligned" the scales are, the better the fish with or without fukurin.

For example, suppose you have two Chagoi of the same color and size. The body is chunky, with big paddle-like pectoral fins. The scales' alignment is the key distinction between the two. The fish with the most consistent, straight rows would be rewarded with a point for scale pattern if the rows were nice and straight like a corncob.

Gin Rin Scalation (Diamond Shimmer)

Chagoi can also manifest in a ginrin scalation. When proteins inside the scale (beneath the epidermis) are thrown up in folds, refracting light and producing a diamond shimmer, this is known as a ginrin scalation or diamond shimmer. The Rootbeer Chagoi, which has ginrin on its scales, is one of the most beautiful koi species.

On the Basis of Colors

Though most Chagoi koi are brown, there are a variety of hues under this broad umbrella. Following are a few of the most popular choices;

Green Chagoi 

Green Chagoi are among the most friendly of all the Chagoi colors. This is probably due to the fact that green Chagoi always seems to be starving. They are the hungriest koi variety. Second, despite the fact that the green Chagoi lightens over time and turns brown, it continues to show (early) that the fish will grow to be a true master of scale.

Green Chagoi are most beautiful when they are young, just three to four years old, and are tan-greenish in color. When the green Chagoi eventually fades to brown, it develops an amber-blonde shade that is superior to the typical brown of a Chagoi. Green Chagoi are available with and without fukurin. Know that a green Chagoi will eventually reach tremendous dimensions if you receive one!

Brown Chagoi

The majority of Chagoi are brown, much like their normal carp relatives. However, they may be found in different shades. Lighter tones reveal that the Chagoi is more valuable.

If you have a brown Chagoi, it's likely that fukurin should be included to distinguish it from other carp. The brown Chagoi is the most common of the Chagois, and you will be overjoyed with it.

Root Beer Chagoi 

The Root Beer Chagoi has a reddish hue to the largely plain brown tones. This type of koi is available in both with or without the fukurin pattern.


The body of this fish is brown with a black fukurin pattern, but the fish is bruised with black smudges on it. The better the fish, the deeper and more distinct the black, and the more organized the design are.

Chagoi Utsuri exists with a faint black pattern that is unevenly stretched over the body and there are others that are extremely artistic-looking, with deep black markings distributed equally from left to right and front to back. A fish like this should be purchased on the spot. They are very uncommon, so regret is a costly thing to have when you find out how rare these creatures are.

The Chagoi is a descendant of the Ochiba Shigure and Soragoi, but, while you consider purchasing a Chagoi, keep in mind that despite its modest hue, it is highly valued for redeeming characteristics such as size, scale alignment, and attitude. You'll fall in love with your Chagoi! Please remember that, as with any other new fish, you should quarantine any new additions to your collection.

Tips to Feed Chagoi Koi From Your Hands Like an Expert

Tips to Feed Chagoi Koi From Your Hands Like an Expert 

Having your prized fish greet you every morning or night, eagerly waiting at the pond's edge for a handful of Koi food or a Koi Treat, is one of the most gratifying experiences in Koi keeping. In some cases, fish learn to adapt and associate your footsteps with the delivery of food to the pond. In other circumstances, it appears as though the fish never get used to the steps and always wait until activity around the pond edge has ceased before coming up to eat.

Adding a fish variety that is naturally really amiable to your tank is one of the most tried and true ways of soothing your fish and encouraging them to accept your presence.

The Chagoi, Soragoi, and Ochiba Shigure fish are the most sociable ones that will gladly eat out of your hand after just a short while. Adding one or two Chagoi fish to your collection can rapidly teach the remaining fish that it's OK to greet you at the pond side in order to receive a treat.

Here are some tips for making fish more friendly while hand feeding:

  • Feed your fish two to three times a day using food that they love. This is usually a 35-45% protein diet with high levels of fish ingredients.

  • Before adding the food, wait two to five minutes by your pond. This teaches the fish that your presence is related to the addition of food. If you approach, toss the food into the pond, and depart immediately, the fish will have no memory of you as a food provider.

  • Offer the fish a delectable treat. Koi will devour whole freeze-dried krill, as well as their own line of specially made Koi Treats.

  • Add one or two of the above-mentioned fish to the group. Your group of fish's attitude might be radically altered in a few days as a result of this. Make sure the fish you're adding are comparable in size to those already in the pond. A six-inch fish may not be able to lead a thirty-inch fish up to eat with ease.

  • If you want the fish to take food out of your hands, hold a snack like a krill on the bank and watch their reaction when the Koi come near. There isn't much training required if the Koi come immediately to your hand to eat the krill. If the koi swim straight toward a food source and then back off, it's better to release the krill and let it float into the pond. After a few days to a week of this training, the Koi should come closer to your hand each day until they realize that your hand is not a danger and holds the goodies that they're seeking.


What Does Chagoi Mean?

Chagoi comes from the Japanese word "cha," which means tea. This indicated the wide range of colors for koi of this sort.

How Can You Tell if a Koi Is a Chagoi?

One way to tell if a koi is a Chagoi is by its color. Chagoi is brown, tan, or grey with darker spots on their sides. They can also be identified by their large size and long fins. If the koi's head and shoulders are broad, and no part of the fish is slender or streamlined, Then it is a Chagoi koi. The pectorals of Chagoi are large and paddle shaped, and there won't be any splits in the fins or the dorsal fin. The eyes of a Chagoi koi look very active and bright, with the corneas being crystal clear.
