Known from the Mekong basin around Pak Beng to the Khone Falls (Ref. 37772). Found in Ban Hang Khone at Don Khone, about 3 km below the fall line of the great waterfalls of the Mekong River at Lee Pee (Ref. 9497). Enters flooded forest (Ref. 9497). Specimens of this species previously reported from Ban Hang Khone (Ref. 9497) have been reidentified as O. exodon (Ref. 12369). This fish probably does not occur naturally in the Mekong basin (Ref. 12369). Also Ref. 4792, 4796, 31465, 56905.
