The Dark chub (Nipponocypris temminckii) is a freshwater fish of the family Cyprinidae that grows up to 17 cm.
Description
The dark chub is a slender East Asian cyprinid of the family Cyprinidae reaching about 17 cm. The laterally compressed body bears a dark stripe along the flank; breeding males colour spectacularly with red and blue-green tints and develop small breeding tubercles on the head. The species lives in schools in clear, flowing streams and rivers with gravel and stone bottoms in Japan, Korea and China. As an omnivore it eats insects from the surface and bottom, algae and small crustaceans. In spring it spawns over gravel, where the male defends a spawning site. It is a common stream fish of East Asia and a prey fish for larger species and waterbirds.
