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. About 27 species, some extremely rare and endangered, and some 2-4 may already be extinct.

Most of these species are quite small, with maximum lengths in the 2-4 cm range, making them of interest for aquaria.

Several species carry their eggs attached to the body between their pelvic fins.

The medaka, "Oryzias latipes", is a popular model organism used in research in developmental biology.

Genetic study of the family suggests that it originally evolved on Sulawesi and spread from there to the Asian mainland; the supposed genus "Xenopoecilus" are apparently unrelated, morphologically divergent species of "Oryzias" (Takehana "et al.", 2005).
