Japanese koi fish are specifically bred for both coloration and form. The ideal environment for koi is a pond, of at least 1000 gallons, with plenty of cover and adequate filtration. Koi are very resilient fish that can survive winter in a frozen pond, provided a hole is maintained in the ice with an airstone or floating heater for gas exchange.
The koi (Cyprinus carpio) is a larger relative of the goldfish. Ornamental ponds in Japan have featured selectively bred koi for centuries. Koi can thrive in temperate and subtropical climates, making them ideal for outdoor ponds in much of North America, Europe and Asia. Almost all koi are the same species, though some varieties were created through hybridization with closely related species of carp. Dozens of varieties and sub-varieties of koi exist, delineated by their coloration and finnage.
The Butterfly Koi boasts long, flowing fins that add grace and peace to even the largest backyard oasis. It is appropriately named for its long, flowing fins often resembling butterfly wings. It is these longer, distinct fins that differentiate the Butterfly Koi from standard Koi. The Butterfly Koi is available in a variety of colors and patterns, but is most commonly available in white, yellow, orange, or a combination of these colors. While Butterfly Koi can live longer than 200 years, their typical life span is 25 to 35 years.
Shubunkins are similar to the common goldfish in appearance. They possess nacreous scales (an intermediate between metallic and transparent scales that are pearly in appearance). The overlapping patches of red, white, blue, grey and black (along with dark speckles) normally extend to the finnage of Shubunkins. Shubunkins are excellent pond fish because they reach a length of 9 to 18 inches at adulthood.
Black Moor goldfish are popular because they are hardy fish and because their black color sets them apart from the more common gold color. Goldfish are typically easy to care for. Black moors in particular are able to withstand a wide variety of temperatures. They do well with other fancy goldfish varieties.
