Lanshou goldfish
Ranju can be said to be the king of Japanese goldfish (definitely introduced), representing the pinnacle species of Japanese goldfish. Because Lanshou is an egg-type hairy fish, that is, this kind of goldfish does not have a dorsal fin and has tumors on its head. Many strangers may not know the difference between Chinese goldfish and Lanshou goldfish, so I will introduce them to you in detail.
There are obvious differences between Lanshou goldfish and traditional Chinese goldfish: its body is longer, its back is broad, and its tail barrel is strong; although there are tumors on the head, they are not developed, only on the top of the head. Compared with the corners of the mouth, the gills on both sides are relatively thin. Such development characteristics make the head of Lanshou goldfish close to a rectangle when looking up, while the body is close to a trapezoid. In addition, the parent bones on the caudal fin (that is, the two outermost large fin rays) are stiff, and the caudal fin is spread out to nearly 180 degrees. This makes the overall style of Lanshou Goldfish extremely flexible and concise, with a domineering side. This is different from the short, round, fat and silly festive temperament pursued by traditional Chinese goldfish. It can be said to be the difference between "dynamic" and "quiet".
