Pseudorhodeus
Tokyo bitterling
Species of fish
The Tokyo bitterling (Pseudorhodeus tanago) is a temperate freshwater fish of the carp family (Cyprinidae). Taxonomically, it belongs to the subfamily Acheilognathinae.
The species was first described as Rhodeus tanago by Shigeho Tanaka in 1909. It is widely known as Tanakia tanago,[2] although a 2014 study suggests it is genetically distinct from other Tanakia species, and warrants placement it the monotypic genus Pseudorhodeus.[3]
