Orange Oranda with a white full faced cap (wen)

An oranda is a breed of goldfish characterized by a prominent bubble-like "hood" on the head. The headgrowth or hood (also known as wen) may be a prominent growth on the top of the head (cranial region) or may encase the whole head except for the eyes and mouth.[1][2][3]

When it was first imported from China to Japan it was mistakenly thought to be native to Holland, and was therefore dubbed the "Dutch Ironmask" (オランダ獅子頭), from which its English name "oranda" derives.

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. The headgrowth is described as a 'wen' by Chinese aquarists. The oranda is a metallic or matte scaled goldfish. 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.[4][2][3]

The headgrowth of young fry may take one to two years to develop.[4][2] The oranda can reach 20 to 31 centimeters (8 to 12 inches) in length.[2][3] Sometimes the wen grows enormously covering the eyes of the goldfish. Due to this, the eyesight may become limited or even blind. 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 fish are very rare.[5] Oranda goldfish are especially sensitive to cold temperatures, more so than other goldfish.

Special care

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 make sure that they do not starve because of the able-sighted competition. Their wen is also susceptible to injury from rough objects placed in their residence.
