The Black Koi will all vary in appearance, and will change further as they age. They are often a coppery brown color with white underneath, fading to a dark gray or black. As the fish matures the color will generally darken up to more solid black with age. A native of Eastern Asia, these beautiful, animated, hardy, specimens are completely peaceful even at their maximum captive length of more than two feet. Koi can survive winters in many areas of the U.S. Simply allow oxygen exchange by ensuring that a hole exists in any solid ice that might form on the top of the pond. These gentle giants can live in captivity for decades. They are aggressive eaters, yet can adapt to eat from the owner's hand.
