different types of goldfish
TYPES OF GOLDFISH. There are over 100 types of goldfish! All of the goldfish breeds belong to one of two types. The two types are the ORDINARY goldfish and FANCY goldfish. Ordinary goldfish have only one tail, while fancy goldfish have two tails. The common goldfish is an ordinary goldfish. It has a narrow body, which makes it a fast swimmer.
Both the London and Bristol variety are one of the more hardy types of goldfish. This makes it an ideal goldfish for an outdoor pond or an indoor goldfish aquarium. If you do choose to stock your tank or pond with shubunkins, avoid mixing them with the slow moving bubble eyes or celestial goldfish.
The comet goldfish is similar to the common goldfish types and is often mistaken for it, but the comet has a more slender body with more noticeable and elongated fins; especially the caudual fin, which is more than half to three-quater the size of its own body.
