The cardinal fish ( Tanichthys ) are a genus of carp-like freshwater fish to which four species belong. It occurs in tropical southern China and Vietnam .
features
The size of the fish varies between about two and four centimeters. The body is elongated, slightly flattened on the sides and has inconspicuous colors. The flanks are patterned with pink, green and black vertical stripes. The mouth is above, the lower jaw is slightly above the upper jaw. A lateral line organ is missing on the head and body. Barteln, the symphysis button of the lower jaw and a keel are missing. The pharynx are in two rows. The two front and rear nostrils have grown together and each form an elongated opening. The base of the dorsal fin is short, without a spiny fin ray. The base of the anal fin is also short. It is not framed by a series of enlarged scales. The vortex centers of the second and third vertebrae have not grown together. During the breeding season, males have a spawning rash with four to eight horny tubercles in a row behind the intermaxillary bone (premaxillary).
Cardinal fish are swarm-forming omnivores . They are ovuliparous , which means that the females lay eggs, which are then fertilized by the males outside the body.

Systematics
The genus Tanichthys was described by Lin Shuyan in 1932 and named after Tan Kam Fei, a Chinese scout leader who discovered the cardinal fish ( Tanichthys albonubes ). It was originally assigned to the carp fish (Cyprinidae). The British ichthyologist Richard Mayden and his Chinese colleague Wei-Jen Chen placed them in their own family, the Tanichthyidae, in 2010. The scientific fish database Catalog of Fishes took over this and now manages the cardinal fish as well as the other former subfamilies of the Cyprinidae as independent families. The cardinal fish are the sister group of the white fish (Leuciscidae).
