RICEFISH

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).
