The ornamental koi originates from the drab carp now found across most continents.
Individuals with color mutations were selected and bred from to enhance their visual appeal.
The earliest records of single color koi are from Japan. Here this fish is common in the water courses and ponds of Japanese style gardens.
Caring For Koi
As koi carp grow to a significant length they require a pond at least a meter and a half in length. When cared for in a comfortable pond this fish can successfully live for more than 30 years quite easily. Amazingly the oldest koi carp to be reported made it to the ripe old age of 200 years.
This cold water fish will tolerate winters outdoors but should not be fed once the water has sunk below 10 degrees Celsius. Koi food will typically float on the surface so that the fish can be examined and accounted for during feeding. They contain both plant and animal matter as the ornamental carp's diet is that of an omnivore.
Young koi especially will require protection from predators. Deep water, thick plants and in come cases netting are good steps to take.
Selective breeding has created all kinds of color combinations. The following are recognized varieties of ornamental koi.
