Diagnosis: more elongated, more slender and somewhat more depressed than Gobiocichla wonderi (Ref. 52307), with a shallower caudal peduncle and smaller eyes (Ref. 53766). Scales reduced; dorsal fin never with "tilapiine" spot (Ref. 7378, 31256, 53766, 53784). Upper jaw relatively non-protrusible; groove between upper jaw and snout greatly reduced, insignificant or absent near snout-tip; mouth slightly narrower and more subterminal; snout tip visible from below; body horizontally oval in cross-section; 18-19 dorsal fin spines and 11-12 soft rays; 3 anal fin spines and 10-11 branched rays (Ref. 53766).
Rheophilic, found near river banks, primarly in small caves and cracks in stones, in flowing water with high turbulence and water speed (Ref. 52307). Found only in rocky habitats with little or no sand or gravel (Ref. 53766). Presumably feeds upon plants and other organisms which grow attached to the rocky substrate (Ref. 53766). Forages on algae using specialised, abrupt movements of the head (Ref. 52307). Probably a cave-spawner that practices pair-bonding, albeit weakly (Ref. 52307).
