The Red cap Oranda is a beautiful gold fish with a large round body, shimmering scales, and a long flowing split caudal (tail) fin that fans out when it comes to a stop. The Red Cap Oranda Fancy Goldfish are favored for their hood, a fleshy growth on the top of the head called the wen. The wen starts to show at about 3 - 4 months, but really begins to form at about 1 - 2 years becoming full in 2 - 2 1/2 years. Unlike the common goldfish with a long slender body, the Redcap Oranda Goldfish is one of the more rounded or egg-shaped fancy gold fish. It is totally white except for a cherry red hood on its head, looking just like a cap. All of its fins are paired except the dorsal fin, and the tail fin is usually split. The Redcap Oranda Goldfish are very popular, but although they are widely available they are considered delicate and not recommended as a beginner fish. Unlike the flat-bodied types of goldfish, they have a lower tolerance for pollution and cannot tolerate extremely cool temperatures. The hood is subject to infection from debris, bacteria, and fungi that settles in the tiny folds. For more goldfish information, see: |

Habitat: Distribution / Background
The goldfish of today are descendants of a wild carp fish, known as the Prussian Carp, Silver Prussian carp, or Gibel Carp Carassius gibelio (syn: Carassius auratus gibelio) which was described by Bloch in 1782. For many years it was believed that goldfish had originated from the Crucian Carp or Golden Carp Carassius auratus auratus described by Linnaeus in 1758, but more recent research is pointing toward the former.
These wild carp originated in Asia; Central Asia (siberia). They inhabit the slow moving and stagnant waters of rivers, lakes, ponds, and ditches feeding on plants, detritus, small crustaceans, and insects. In the early 1500's these fish were exported first to Japan and then to Europe and were developed into the wonderful colors and forms of gold fish we see today.
The Oranda Goldfish is one of the older fancy goldfish with the Redcap Oranda variety being an early development. Today there are more than 125 captive bred fancy varieties.
The Redcap Oranda Goldfish is an egg-shaped variety of goldfish. The body has a large round shape, shimmering white scales, and a long flowing split caudal (tail) fin that fans out when it stops swimming. All of their fins are paired except the dorsal fin, and the tail fin is generally split. They have fleshy growth or hood on the top of the head that is a bright cherry red.
Redcap Oranda Goldfish are some of the more delicate species of goldfish. Unlike the flat-bodied types of goldfish, they have a lower tolerance for pollution. Its hood is subject to infection from debris, bacteria, and fungi that settles in the tiny folds. They will need good care and plenty of space,
Many people will keep goldfish in small one or two gallon goldfish bowls with no heater or filtration. But for the best success in keeping goldfish, provide them the same filtration, especially biological filtration, that other aquarium residents enjoy.
Since they are omnivorous, the Redcap Oranda Goldfish will generally eat all kinds of fresh, frozen, and flake foods. To keep a good balance give them a high quality flake food everyday. To care for your Redcap Oranda Goldfish, feed brine shrimp (either live or frozen), blood worms, Daphnia, or tubifex worms as a treat. It is usually better to feed freeze-dried foods as opposed to live foods to avoid parasites and bacterial infections that could be present in live foods. Due to their fleshy head growth they can have poor vision and a harder time seeing their food, so need extra time to feed.
Regular weekly water changes of 1/4 to 1/3 is strongly recommended to keep these fish healthy. Snails can be added as they reduce the algae in the tank, helping to keep it clean.
Setting up an aquarium in a manner that will keep your fish happy and healthy is the first step to successfully fish keeping. Here are aquarium parameters to consider in choosing goldfish aquariums, filtration, lighting, and decor as well as temperature and water movement.
Goldfish are very social animals and thrive in a community. Not only are they a great community fish but they are great scavengers as well. It is really not necessary to add other scavengers or other bottom feeders to the aquarium when you have goldfish.
The Redcap Oranda is not a fast swimmer. They cannot vigorously compete for food with fast swimming types of goldfish like the the Common Goldfish, Comet Goldfish, the Shubunkin, so may not fare well if housed with them, but they will do well housed with other egg-shaped varieties if the environment is well cared for.
Although is it impossible to sex Goldfish when they are young and not in breeding season, the male is usually smaller and more slender that the female. In the breeding season the male has white prickles, called breeding tubercles, on its gill covers and head. Seen from above the female will have a fatter appearance as she is carrying eggs.
Redcap Oranda Goldfish are egg layers that spawn readily in the right conditions. See Breeding Freshwater Fish - Goldfish for more information on breeding Goldfish.
Goldfish are subject to the same diseases as tropical fish. A couple of the more common problems are Ich, Swim Bladder Disease, and external parasites including flukes, lice and anchor worms. For more in-depth information about goldfish diseases and illnesses, see: Goldfish Care; Fancy Goldfish and Goldfish Diseases.
The Redcap Goldfish is readily available in fish stores and on-line, and is inexpensive.
