Koi Fish: What You Should Know About Their History And The Various Types Of Koi
Koi are very popular fish bred and taken care of by hobbyists the world over. Koi is a Japanese word which means "carp" and includes the dull gray wild carp caught in rivers and lakes for food, along with the brightly colored varieties. It is the vibrant koi fish that are bred for their beauty. Although the proper expression for these "living jewels" is nishikigoi, many people, particularly those in the United States, refer to them simply as koi.
A Very Koi Story
The carp originated from Central Europe and Asia where it was simply a food fish. It was the Chinese who started to propagate selected species of carp until they developed the gold fish more than a thousand years ago. The Chinese first brought koi as food to Japan in 200 AD. Seeing the wonderful color mutations, Japanese farmers in Niigata, a prefecture in Honshu, bred them for ornamental purposes and produced a number of color designs. The first kind to be established is the kohaku, the red-and-white koi.
The Niigata koi was first seen by the community in 1914 during the annual exposition in Tokyo. The beautiful, colorful fish captivated the whole of Japan and many kept koi because they looked great for their water gardens. It did not take long before the rest of the world caught up on the hobby. Nowadays, Niigata remains to be the home of the best koi breeders although you can buy koi from most pet stores. However, you have to go to specialized dealers if you prefer the higher-quality fish. Prices of koi vary according to the very koi-like feature of the fish.
Koi Characteristics
You can find koi with various colors and patterns. The usual colors are white, black, red, yellow, blue and cream. Female koi are generally plump while the males are a lot more sleek with torpedo shapes. A matured koi can grow as long as 36 inches and weigh over 17 pounds. The koi are hardy and durable, and can live for many years depending on their genetics and living conditions. The oldest koi ever documented was "Hanako" that supposedly lived around 226 years.
The Koi are omnivores and eat almost anything including vegetables. It is very koi of the fish to look for food at the bottom of the pond. Although koi fish are basically shy and will run away when disturbed, they usually recognize the person regularly feeding your koi fish. It is ordinary to see koi gathering close to their keeper during feeding times with some eating directly from the hand.
Varieties of Koi
There are several kinds of koi that are distinguished by the color, pattern and also scales. There are some hybrids like the Ghost koi and Butterfly koi that have also gained popularity but are not regarded as true Nishikigoi. One of the prominent types of the true Nishikigoi are the following:
- Kohaku - white koi with big red markings on top
