Medaka Rice Fish (ORYZIAS LATIPES VAR. "YOUKIHI")
Also known as the Japanese Rice Fish/Killi Fish or Orange Rice Fish. This is one gorgeous fish that doesn't get too big and does very well in a planted tank with other peaceful smaller fish such as Celestial Pearl Danios, Dwarf Gouramis and peaceful schooling Tetras.
Keep them with a number of females as the males show beautiful colors!
