Genus of fishes From Wikipedia, the free encyclopedia
Oryzias is a genus of ricefishes native to fresh and brackish water in east and south Asia.[4] Some species are widespread and the Japanese rice fish (O. latipes) is commonly used in science as a model organism, while others have very small ranges and are threatened.[4] They are small, up to 8 cm (3.1 in) long, and most are relatively plain in colour.[5]
