The Nippon Baratanago (Rhodeus smithii) is a freshwater fish of the family Cyprinidae that grows up to 7 cm.
Description
The Japanese bitterling is a small cyprinid relative (Acheilognathidae) from Japan. The species has a deep, laterally compressed, silvery body; in the spawning season the males colour brightly. Characteristic is its reproduction: with a long ovipositor the female lays her eggs in the gill cavity of a living freshwater mussel, where the young grow up protected. It feeds on algae, small zooplankton and detritus. Owing to habitat loss and decline of the host mussels the species is critically endangered. It is harmless to humans.
