The word 'coy' in coy fish is derived from koi, the Japanese name for carp. They originated in Eastern Asia, Aral Sea, Black Sea and Caspian Sea. These are widely cultivated fish in China and Japan. The breeding of these fish first became popular in Japan in the 19th century when farmers accidentally discovered these brightly colored creatures and started to raise them. Gradually it became popular throughout Japan but the rest of the world still was not aware of this kind of fish. When the use of plastic bags became popular, the shipping of coy became faster and safer. Thus their shipping began to other countries, throughout the world. They are now found in most of the pet stores. There are both, the colorful varieties as well as the dull gray variety of coy fish. In Japan this fish symbolizes love and friendship.

Coy Fish Care
Coy fish is a coldwater fish and is therefore advised to keep in areas that are harshly cold. They should be kept in a pond with a minimum diameter of 1.5 meters and depth of about four and a half feet. If you intend to keep the fish in areas that are comparatively hotter, it is recommended to increase the depth of the pond by at least another feet. When the temperature of the cold areas drop below 50°F, coy fish go into a state of hibernation. They remain at the bottom of the pond as the top layer of the pond freezes and stay there until the ice begins to melt during spring. During winter their digestive system halts and they survive only on algae found at the bottom of the pond. Normally, these fish can devour anything from lettuce, peas to watermelons to insect larvae.

The attractive and distinct colors of coy fish may make them a vulnerable target for predators. Cats, raccoons, birds can easily access the pond and scoop out the fish. Hence, it is necessary to protect the pond from coy predators. Setup an overhang on the pond to prevent mammals from getting inside the pond. Planting tall, shady trees around pond can obstruct the view of aerial predators. You can even place a wired net on the pond.
Life Span
If the conditions are favorable and ideal, they can live for up to 90 years. The record lifespan for coy fish is 226 years. However, the ones living in artificial pond in a controlled environment can live up to 50 - 60 years. Those in wild can easily surpass this average lifespan. Ideal conditions for the survival of coy fish are clean water, large area and fresh food. They live longer if kept with other pond fish as well as with their own kind.
Coy fish can be a great addition to your backyard landscape. Besides, they keep the pond clean by devouring insect larvae. If you care properly for your coy fish, you can pass them to your next generations.
