The Tokyo bitterling (Pseudorhodeus tanago) is a temperate freshwater fish of the carp family (Cyprinidae). Taxonomically, it belongs to the Acheilognathinae sub-family.[2]
In the wild, it is found only on the Kantō Plain of Japan, an area near to the capital city of Tokyo. It was formerly abundant in small streams, but its habitat has been overrun by people and pollution, and it was listed in the 1996 IUCN Red List as "Vulnerable", and there is a real risk that it could become extinct in the wild. It also suffers from competition from the related but more aggressive rosy bitterling. Bitterlings lay their eggs in mussel shells, and the Tokyo bitterling will only lay its eggs in one type of mussel shell, limiting its chances of successful breeding. To help protect it, it has been declared a "national monument" by the Japanese government which gives it special protection.
It was first described as Rhodeus tanago by Shigeho Tanaka in 1909. The fish reaches a size of up to 5 cm (2.0 in) TL.[2]
