背面の脊椎 (合計) : 6 - 7; 背鰭 (合計) : 8 - 10; 肛門の骨: 1; 臀鰭: 13 - 17; 脊つい: 32 - 35. This species with well-contrasted dark lateral body stripes, is distinguished by the following set of characters: D V-VI,I,8-10 (mode 9); A I,13-17 (mode 15); procurrent caudal rays 12-15 (mode 13); lateral line scales 30-33 (mode 32); cheek scales often 9-12; total gill rakers on first arch 13-18 (usually 14-16); vertebrae 32-35 (mode 33); body is moderately deep with greatest depth 2.8-3.7 (mean 3.3) in SL and greatest width 1.8-3.1 (mean 2.2) in HL; maxilla is relatively long 3.0-3.8 (mean 3.4) in HL; long predorsal distance 1.9-2.3 (mean 2.1) in SL. Colouration: when alive bronze to brown body lighter on ventral half with a series of dark brown lateral stripes; fins are orange to rich red especially in nuptial males, sometimes with lines of spots or a horizontal line near base but never as a thick submarginal band (Ref. 121823).
Inhabits lowland swamps and small streams, usually in clear, acidic waters with ample cover in the form of log debris or aquatic vegetation. Occurs at temperatures ranging from 24-30° C (Ref. 5259). Found in clear waters of small creeks and Pandanus swamps. pH range is 5.5-7 (Ref. 44894). Commonly co-occurs with Melanotaenia splendida and is often found in association with other wetland fish species particularly Pseudomugil gertrudae and Oxyeleotris nullipora (Ref. 121823),
