An oranda is a type of 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.[1][2][3]

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 a 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.[2][3]
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.[1][2][3]
The headgrowth of young fry may take one to two years to develop.[1][2] The oranda can reach 20 to 31 centimeters (8 to 12 inches) in length.[2][3] A specimen from China, named "Bruce" (after late actor and martial artist Bruce Lee), has attained 15 inches in length.[1] Sometimes the wen grows enormously covering its eye. Due to this the eyesight is either limited or the fish has no vision. Special care should be given to the wen because it is prone to bacterial infections. The Oranda can tolerate temperatures from 17-28°C (65-80+°F).More recently blue scale oranda have been developed but these fishes are very rare[4]. Oranda goldfish are especially sensitive to cold temperatures, more so than other goldfish.
Orandas are sensitive to low water temperatures and susceptible to the attention of other active goldfish.[2] If their wen grows too much, it may hinder vision, so it is advised to keep them with others that have this disability in order to ensure they do not starve because of the able-sighted competition. Their wen is also susceptible to injury from rough objects placed in their residence.
