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. 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 oranda can reach 20 to 31 centimeters (8 to 12 inches) in length. A specimen from China, named Bruce (after late actor and martial artist Bruce Lee), has attained 15 inches in length. The Oranda can tolerate temperatures from 17-28C (65-80+F). More recently blue scale oranda have been developed but these fish are very rare. Oranda goldfish are especially sensitive to cold temperatures, more so than other goldfish.
