Common Name

Biology
Dorsal spines (total): 0 - 1; Dorsal soft rays (total): 8-9; Anal spines: 1 - 2; Anal soft rays: 27 - 29; Vertebrae: 30 - 31. Can be distinguished from other species in possessing the following combination of characters: a thick-set body (body depth 30.5-33.7 % SL) with the anterior part of the body reminiscent of the taxon Anabas; head devoid of pattern except for a preorbital stripe that runs from the black lower lip to the eye, and continuous with a postorbital stripe to the posterior edge of the opercle; in living specimens, the opercle with faint gold iridescent scales; and some median caudal rays projecting beyond the fin margin (Ref. 81926).
