Cobitis minamorii is a species of fish in the family Cobitidae found in Honshu, Japan. Five subspecies have been proposed. Japanese name is kogata-suji-shima-dojyô.[2][3] English name is Small stripe spined loach.[2] This species is listed as a new species in 2012.[2][3]

They inhabit sandy-mud bottoms of the lower reach of rivers and small lowland stream. The number of current population is decreasing because these habitable environment is decreasing.[3][4]They are found in western Honshu:Okayama, Shimane, Tottori, Hiroshima, Hyogo, Osaka, Kyoto, Shiga, Mie, Gihu, Aichi, Shizuoka.[4]

Their spawning season is May-August. They invade a temporary wetland such as rice field and lay eggs at the bottom of the mud. These eggs hatch during one day. They mature in one year and live in approximately 3-5 years under breeding. They grow up to 10 cm in total length.[3][4] Minamorii, their specific name, comes from Japanese resercher who study speciation of Japanese loaches first. [2]
