Crucian carp travel in groups, always staying close to one another.
Crucian carp were domesticated in China over a thousand years ago. Later, a golden variant emerged, becoming the ancestor of today's goldfish and eventually forming a distinct breed. Accounts of Strange Things records: "Goldfish have been kept since the Song, now they are found in households everywhere for amusement." However, breeding golden crucian carp was once a secret art. It was rumored that feeding them a certain small red worm would gradually brighten their color. It wasn't until the Ming and Qing dynasties that breeding techniques became more advanced and standardized.
