The ricefishes are a family (Adrianichthyidae) of small ray-finned fish that are found in fresh and brackish waters from India to Japan and out into the Indo-Australian Archipelago, most notably Sulawesi. The common name of the group derives from the fact that many species are found in Japanese rice paddies. This family consists of about 32 species, some extremely rare and endangered, and some 2-4 may already be extinct.
