Spine dorsali (totale) : 12 - 14; Raggi dorsali molli (totale) : 5 - 6; Spine anali: 11 - 13; Raggi anali molli: 8 - 10. Differs from its congeners by the following unique combination of characters: 12-13 spines in dorsal fin; 11-13 spines in anal fin; 8-10 segmented rays in anal fin; in live males, dorsal, anal and caudal fins with a narrow bluish margin and a black subdistal band bordered proximally by a bluish iridescent band, sometimes turning to reddish posteriorly; proximal part of dorsal and anal fins from dark red to black; proximal part of caudal fin red, darker in basal area; pelvic fin blue, with white filament (Ref. 56232).
Body shape (shape guide): elongated.
Facultative air-breathing (Ref. 126274); Occurs in peat swamps (Ref. 56232).
