Oranda goldfish

An Oranda is a type of goldfish characterized by a fleshy outgrowth on the top of its head and sides of its face, called a wen. Standard Oranda goldfish have a dorsal fin and paired anal fins. Orandas can survive in temperatures ranging from 65-78 °F, in water with a pH of around 7 to 8, and are best fed a collection of fresh foods or hand made food due to the frequency of Flip-Over cases seen in these fish.

Due to the design of the wen, and the fact that it appears to grow in stages or bursts during the spring and fall season, they can be prone to bacterial infections and goldfish “pimples” on the wen. Most of the time they do not require any treatment, but if the lesion turns red steps should be taken to avoid infections. Also, sometimes the wen can overgrow the eyes of the fish, causing it to have limited or no vision. These fish should not be destroyed as they can still function without their eyesight. The wen can be trimmed, but most of the time it simply regrows.

A common fancy version of this fish is called the Red Cap Oranda. It is characterized by a solid white body with a red colored wen. Due to the genetics of the coloring, it is often the case that Red Caps will lose their redness as they age, becoming solid white fish. More recently Blue Scaled Orandas have been developed, and are becoming more and more common.

The Oranda is a highly favored fish with many beautiful qualities, and is compatible with other fancy varieties of goldfish.
Like many other fancy goldfish varieties, prolonged periods of cold are not advisable for the Oranda. They must not be kept below 55 degrees Fahrenheit for long periods of time.

The Oranda is one of the larger fancy goldfish varieties growing up to 7 – 8 inches. One specimen from China named Bruce has attained 15 inches in length.
