The golden mandarin fish (Siniperca scherzeri), also known as the leopard mandarin fish, is a species of freshwater ray-finned fish, an Asian perch from the family Sinipercidae, which is native to eastern Asia (Korea, China, and Vietnam). This species can reach at least 33.4 cm (1.1 ft) in standard length and 607.3 g (1.34 lb) in weight. It is typically yellowish-brown with blackish-brown speckles ("leopard"), but there are also bright yellow ("golden") individuals, which are particularly prized in Korea and selectively bred in captivity.
