Adrianichthyidae
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.About 32 species, some extremely rare and endangered, and some 2-4 may already be extinct.Most of these species are quite small, making them of interest for aquaria. The largest species, the Buntingi, is 20 centimetres (7.9 in) in length, but most are less than a fifth this length, with the smallest being only 1.7 centimetres (0.67 in) long. They have a number of distinctive features, including an unusual structure to the jaw, and the presence of an additional bone in the tail.
