The Japanese rice fish (Oryzias latipes), also known as the medaka,[2] is a member of genus Oryzias (ricefish), the only genus in the subfamily Oryziinae. This small (up to about 3.6 cm or 1.4 in) native of Japan is a denizen of rice paddies, marshes, ponds, slow-moving streams and tide pools.[3][4] It is euryhaline, occurring in both brackish and freshwater.[3] It became popular as an aquarium fish because of its hardiness and pleasant coloration: its coloration varies from creamy-white to yellowish in the wild to white, creamy-yellow, or orange in aquarium-bred individuals. Bright yellow, red or green transgenic populations, similar to GloFish, have also been developed, but are banned from sale in the EU.[5] The medaka has been a popular pet since the 17th century in Japan.[6] After fertilization, the female carries her eggs attached anterior to the anal fin for a period before depositing them on plants or similar things.[5]
