The Chinese rice fish (Oryzias sinensis) is a species of fish in the genus Oryzias. This freshwater fish occurs in swamps, stagnant parts of streams, rice fields and marshes, and is up to 3.1 cm (1.2 in) long. It was formerly considered a subspecies of the Japanese rice fish (Oryzias latipes). The natural range of the Chinese rice fish is in East and Southeast Asia, including the Yangtze, Mekong, Irrawaddy, Salween, Red River and Nanpangjiang basins. It has been introduced to Kazakhstan and Russia (in the lower Kuban drainage); also spreading in the Azov basin and has been discovered in the Obytichna River in Ukraine.
