What is Oryzias latipes?
[[File:Oryzias latipes(Hamamatsu,Shizuoka,Japan,2007)-1.jpg|thumb|]] '''''Oryzias latipes''''', also called the medaka or Japanese rice fish, is a [[freshwater fish]]. It lives in small streams and waterways. Its body is grayish brown on light yellow. It has a dark brown line on its back. These fish usually lay [[Egg (biology)|egg]]s in spring and summer. They have very strong [[kidney]]s, so they can tolerate more salt than most freshwater fish. If they get used to it slowly, they can live in [[seawater]]. These fish live about one year and several months. ==Appearance== They are approximately {{convert|3.5|cm|abbr=off}} long. Their [[Dorsal fin|dorsal]] and [[ventral fin]]s are far in the back of their bodies. ==Relationship with humans== The medaka fish spawn at about the same time of year that people put water into rice [[Paddy field|paddies]], so they often live in the paddies. ==Food and water== These fish eat [[zooplankton]] and the larva of [[mosquito]]es, which live in the water.
