Smarty Fish
Koi fish are very intellectual. Like a dog or a cat, they can be trained to eat out of your hand and sometimes even out of your mouth. Koi fish are omnivores and are known to munch on pond plants.

Body Works
Koi fish can grow up to three feet long if raised in the ideal conditions. They can become sunburned if a pond is too shallow and has little shade. Koi fish don’t have teeth. Females are larger than males.

The Great Mate
In the mating process, koi fish eat their young, recently-hatched offspring called koi fry. Koi fish need to be removed from the fry during the mating session to preserve the fry.

If a breeder raises a highly sought after koi, it can sell for thousands of dollars. $250,000 is not unheard of for a prized koi fish.

Great-Great-Great-Great Grandpa Koi

The Kohaku is a white variety of koi with red patches and is the most popular in Japan.

A legendary koi named Hanako lived to be the oldest koi of all recorded history. Hanako was hatched in 1751 and lived to the ripe old age of 226, passing away in 1977. This famous Japanese koi lived through the Industrial, American, and French Revolutions, saw the formation of the United States, the invention of electricity and the automobile, survived World War I and II, and even lived into the Vietnam War! That’s one long life span! However, most koi live 30-40 years.

Showing Their Age
While Hanako may have lived for 226 years, the koi’s age was not visible to the naked eye. Microscopic growth marks cover a koi fish’s scales like that of the rings on a tree. These can show patterns of rapid growth or shortage of food.

Representations
Koi fish symbolize many virtues in Asian cultures. They are recognized as symbols of perseverance and endurance, as well as strength and individualism.

Koi are a very intellectual fish and can be trained to feed from an owner's hand.

A Rainbow of Ideals
Because koi fish can develop such an array of colors, it comes as no surprise that each hue has developed a connotation. Gold koi fish represent wealth and prosperity. Metallic koi symbolize success in business. A blue koi is thought to bring serenity. Asagi koi of blue, red, and grey colorings symbolize positivity. Black koi are thought to hold a patriarchal symbolism, with red belonging to the mother, blue to the son, and pink to the daughter.
