Butterfly koi are a beautiful, and alluring variety of koi fish that have grown more and more well-liked among fish hobbyists all over the world. With their long butterfly wings, these lovely fish. Also known as long-fin koi or dragon koi, are a joy to behold. We’ll explore the background of butterfly koi. Their distinctive traits, how to care for them, and why they’re such a beautiful addition to any fishpond in this article.

History of Butterfly Koi

The skill of koi breeding was only beginning to take hold in Japan around the turn of the 20th century, during the post-war era. Butterfly koi were first developed by mating regular koi with wild carp. Which led to the development of fish with longer fins and more slender bodies. Unfortunately, Japanese koi breeders favoured the more conventional koi variations, and these early butterfly koi were not very well liked by them.

Butterfly koi didn’t start to become well-liked in the US until the 1980s. Once American koi breeders became aware of the beauty and rarity of these fish, they started importing them from Japan. Also, they began to breed them in the United States, which led to a larger range of hues and patterns. These are a common selection among koi aficionados nowadays.

Characteristics of Butterfly Koi

The long, flowing fins of butterfly koi are recognised for resembling a butterfly’s wings. The length of these fins, which are longer than the fish’s body, can reach 20 inches. They differ from regular koi in that they have longer fins and a more slender body.

They are available in a vast array of hues and designs, including as white, black, red, and yellow. A few varieties of them even have scales that are metallic or iridescent, giving them a distinctive and captivating appearance.

Dragon koi, a different species of koi, are frequently mistaken for butterfly koi. The dragon koi are normally smaller and have a more rounded tail fin. Despite the fact that they resemble each other in certain ways. On the other hand, they have a longer tail fin, which contributes to their recognisable butterfly look.


The upkeep of butterfly koi is comparable to that of regular koi. They need a sizable pond with lots of swimming space as well as an effective filtration system to keep the water clean. The pH level should be maintained between 7.0 and 7.5, and the ideal water temperature is between 65 and 75 degrees Fahrenheit. They should be provided a balanced diet of protein, veggies, and other nutrients because they are omnivores.

The long fins of butterfly koi are something to be aware of when caring for them. Compared to regular koi fins, they are more fragile and more prone to injury. Avoid placing sharp items in the pond like pebbles or ornaments that might cut off their fins.

Butterfly koi breeding is comparable to rearing conventional koi. Yet, it’s crucial to pick superior parent fish with desirable characteristics, such long fins and vivid colours. Selecting a male and female fish, then allowing them to spawn in the pond, is the breeding process. Within three to four days the eggs will hatch, and a week later the fry will be able to swim unrestrictedly. To stop bigger fish from consuming smaller ones as the fry grow, they should be divided by size.

Why Butterfly Koi are So Attractive

There are various factors that make butterfly koi so alluring. First of all, they are distinguished from other fish species by their long, flowing fins. They swim with a beautiful and elegant appearance due to their fins, which makes them enjoyable to watch. These are also available in a broad variety of hues and designs, giving each fish a distinct personality. They are a magnificent addition to any fishpond because to their shiny scales and iridescent hues that enhance their attractiveness.

The personalities of butterfly koi are equally remarkable. They are curious and clever fish who engage with their owners and eventually learn to recognise them. Even hand-feeding by owners has been known to cause some butterfly koi to surface.This level of interaction makes it a popular choice for pet owners who want a fish that is not only beautiful but also engaging and interactive.

They bring beauty to any fishpond thanks to their long, flowing fins, slim body form, and variety of colours and patterns.
