Chinese classification
By Chinese tradition, goldfish are classified into five main types:
- Dragon eye - Goldfish with extended eyes, e.g. Black Moor, Bubble Eye, and telescope eye
- Egg - goldfish without a dorsal fin. e.g. lionhead (note that a bubble eye without a dorsal fin belongs to this group)
- Wen - goldfish with dorsal fin and a fancy tail. e.g., veiltail ("wen" is also the name of the characteristic headgrowth on such strains as oranda and lionhead)
- Ce (may also be called "grass") - goldfish without anything fancy. This is the type that is usually used in Japanese carnivals, especially for "goldfish scoops."
- Jikin and wakin - goldfish with double tails, but with the body shapes of comets.
These classifications are not commonly used in countries outside of East Asia
