duri punggung lunak (Keseluruhan (total)) : 9 - 12; Sirip dubur lunak: 22 - 27; vertebrata, bertulang belakang: 27 - 29. This species is distinguished by the following characters: similar to Oryzias marmoratus by having dark brown blotches on a grayish-brown trunk, differs from O. marmoratus by having 11 abdominal vertebrae, 12 or 13 transverse scales, a shorter caudal peduncle, terminal mouth, reduced nuchal concavity, scales diagonally aligned aslant to midlateral stripe, and male with round-shaped dorsal fin without yellow margin; differs from O. profundicola (sympatric congener in Lake Towuti), in having a longer snout in both sexes, males with larger head and eyes, and a black margined dorsal fin, and females with shallower body depth at the anal- and dorsal-fin origins; D 9-12, A 22-27; head length 24.4-27.2% SL (male 24.4-26.2%, female 24.6-27.2%); eye diameter 10.8-12.5% SL; snout length 7.9-9.3% SL; body depth at point of anal-fin origin 26.1-30.7% SL (male 27.5-30.7%, female 26.1-28.5%); body depth at point of dorsal-fin origin 24.1–28.4%SL (male 25.0-28.4%m female 24.1-26.8%); caudal peduncle length 8.0-11.2% SL (Ref. 133090).
Cross section: oval.
ll specimens were collected and observed at daytime and this species occurs on gently sloping, shallow shores (1.5 m depth) with large boulders and submerged woods over sand and gravel. It often schools with O. profundicola and O. marmoratus and associated with Paratherina spp., Glossogobius sp., G. favipinnis, G. intermedius, Mugilogobius rexi, M. latifrons, and Nomorhamphus megarrhamphus (Ref. 133090).
