This figure is the Japanese Rice Fish (or Medaka or Japanese Killifish), Oryzias latipes, number 11 from the first series. This is the only beloniforme fish in the set; this order includes other surface-oriented fish like flying fish, needlefish and halfbeaks (but, not killifish—taxonomy can be weird). The Japanese Rice fish is found throughout Eastern Asia*, living in a wide range of shallow and slow-moving bodies of water like rice paddies, marshes, streams and tidal pools (it is a fresh- and brackish-water fish).
