The oranda is a fancy goldfish characterized by a prominent raspberry-like hood encasing its head. The hood or headgrowth (also known as wen) encases the whole head except for the eyes and mouth. Orandas are sensitive to low water temperatures and susceptible to the attention of other active goldfish.

Description

Due to the fleshy outgrowth on the upper half of its head and sides of its face, the oranda has become one of the most popular goldfish.It is described as wen by the aquarists. The oranda is a metallic or matte scaled goldfish that is similar in appearance to the veiltail. It has a large, long and deep body accompanied by a long quadruple tail. This four-lobed and contracted tail normally spreads out broadly when the oranda stops swimming. The back does not rise up to form a ryukin-like hump.

Orandas are available in a variety of colors, most often orange, red, red-and-white, red-and-black, black, blue, chocolate, bronze, white or silver, black-and-white (panda-colored), red-black-and-white (tricolor), and calico colors.

The headgrowth of young fry may take one to two years to develop. The oranda can reach 8 to 12 inches (20 to 31 centimeters) in length.Sometimes the wen grows enormously covering its eye,due to this the eye sight is limited or no vision.These fishes should not be destroyed because they can still manage to survive. Special care should be given to the wen because it is prone to bacterial infections.Oranda can tolerate temperatures from 65-78 °F.More recently blue scale oranda have been developed but these fishes are very rare. Oranda goldfish are especially sensitive to cold temperatures, more so than other goldfish.
