History and Origin of Common Goldfish

A beautiful example of an ideal Common Goldfish

This is the default appearance of goldfish, and is the closest form to the Gibel Carp ancestor of all goldfish breeds.

Because they reproduce and thrive so easily, they are usually bred as food for other fish. Many people therefore assume that this breed is simply used for food and nothing more. But despite the name, Common Golfish do compete in shows, and there are standards for appearance.

Even feeder goldfish would be brilliantly colored compared to the first goldfish though. The deep orange color we take for granted today is the result of centuries of careful selective breeding.

Special Care for Common Goldfish

They require no special care. Common Goldfish are extremely resiliant, and can take a lot of punishment compared to other breeds. They are also very good swimmers, and should not be kept with double-tailed breeds since they will out-compete them for food.

Common Goldfish will live quite well in the open, and are often used as pond fish. They can even survive water being frozen over for brief periods, as long as they have food and enough oxygen, conditions which would kill any of the fancy varieties. Goldfish will sometimes go into a hibernation-like state in these conditions, consuming little if any food over the winter.

Obviously, this is not an ideal environment for goldfish. The fact that they can tolerate cold water does not mean it is good for them. Ideally, water temperatures should be comperable to room temperature.

Ideal Characteristics for Common Goldfish

Common Goldfish have a "wild" type body, similar to that of a wild carp. The body depth should be 3/8 the length of the body. Unlike a wild Carp, the mouth should be part of a smooth rounded curve into the back and stomach, without the "snout" seen in truely wild fish. The dorsal contour should be a smooth arch as well.

All fins should be single and slightly rounded except the Pectoral and Pelvic fins. The Caudal fin should be rounded, and short (1/3 the length of the body or less). All fins should be stiff.

Medium orange is most common, but they have been bred into almost all colors. Gold/Yellow (shown above in the "origin" section) is the most rare, despite the fact that it is genetically easier to breed. Some people claim that this is because gold (yellow) was a color reserved for Chinese royalty, so the common people were forbidden to breed goldfish in that color. So orange became the standard color instead.

Colors that saturate the fins are highly desirable in all breeds of goldfish, including the Common, since they tend to be transparent by default.

Known Variants of Common Goldfish

The Common Goldfish has no recognized variants, unless you count Comets and Shubunkins.
