Developed in China the Lionhead Goldfish
wikipedia


The Lionhead Goldfish is a variety of goldfish similar to the Ranchu.
Both lack dorsal fins, have a double tail, and compact, rounded
bodies.

The Lionhead is usually considered a Chinese variety, while the
Ranchu was developed in Japan.

In general, Lionheads have more extensive head growth but less
arch in their backs than do Ranchus. As breeders throughout Asia
buy and sell breeding stock, a certain amount of overlap now
exists between the two varieties.
