The Kinds Of Koi Fish
Koi are very popular fish bred and cared for by hobbyists around the world. Koi is a Japanese word which means "carp" and covers the dull gray wild carp found in rivers and lakes for food, along with the brightly colored varieties. It is the colorful koi fish that are bred for their beauty. Although the proper term for these "living jewels" is nishikigoi, most people, particularly those in the United States, call them simply as koi.
A Very Koi Story
The carp came from Central Europe and Asia where it was merely a food fish. It was the Chinese that began propagating selected species of carp until they developed the gold fish more than a thousand years ago. The Chinese first introduced koi as food to Japan in 200 AD. Looking at the wonderful color mutations, Japanese farmers in Niigata, a prefecture in Honshu, bred them for aesthetic applications and produced a number of color designs. The first variety to be established is the kohaku, the red-and-white koi.
The Niigata koi was first seen by the public in 1914 in the course of the annual exposition in Tokyo. The beautiful, colorful fish charmed all of Japan and many kept koi because they looked perfect for their water gardens. It did not take long before the rest of the world caught up on the hobby. These days, Niigata continues to be the home of the best koi breeders though you can buy koi from almost all pet stores. However, you have to go to specialized dealers if you want the higher-quality fish. Prices of koi vary according to the very koi-like quality of the fish.
Koi Attributes
You can find koi with various colors and designs. The typical colors are white, black, red, yellow, blue and cream. Female koi are generally plump while the males are a lot more streamlined with torpedo shapes. A matured koi can grow as long as 36 inches and weigh more than 17 pounds. The koi are hardy and tough, and can live for many years based on their genetics and also living conditions. The oldest koi ever documented was "Hanako" that supposedly lived up to 226 years.
The Koi are omnivores and eat almost anything including vegetables. It is very koi of the fish to forage at the bottom of the pond for food. Although koi fish are really shy and will run away when disturbed, they often know the person regularly feeding your koi fish. It is ordinary to see koi gathering around their keeper during feeding times with some eating directly from the hand.
