interradial scales on anal fin; arms in the first epibranchial bone are parallel (vs. divergent); posterior end of dentigerous arm of dentary rounded or squarish (vs. triple-spined or bluntly pointed); peritoneal coloration is uniformly dark (vs. not uniformly dark); rostrad directed pronounced convexity on the ventral process of the articular absent (vs. present); body less deep than as compared with its congeners kanna and siquia; 4th bar not Y-shaped (Ref. 74403). Body shape (shape guide): short and / or deep.
Adults inhabit flowing water from small creeks and streams to the shallows of large and fast flowing rivers (Ref. 7335). Prefer rocky habitats and finds sanctuary in the various cracks and crevices provided by this type of environment (Ref. 7335), or among roots and debris (Ref. 44091). They occur in warm pools of springs and their effluents (Ref. 7020). Feed on worms, crustaceans, insects, fish and plant matter (Refs. 7020; 44091). Also used in behavioral studies (Ref. 4537). Approximately 100-150 eggs are deposited and are vigorously guarded and cared for by both male and female (Ref. 44091). A popular aquarium fish which requires high temperature to maintain itself in an environment, e.g. artificially heated waters of power stations. Aquarium keeping: in pairs; minimum aquarium size 80 cm (Ref. 51539).

Lays eggs on cleaned surfaces of rocks. Parents incubate eggs and guard young. Tends and fans the embryos and free embryos and transfers them several times into new pits excavated in the bottom using its mouth (huddling) (Ref. 34155).
Dark cavities are preferred as nests to conceal the brood and make them less conspicuous to visual predators (Ref. 38966). When in caves, single entrances are favored to reduce the probability of intrusion and are probably more manageable for the females in terms of defending their brood (Ref. 38966). Approximately 100-150 eggs are deposited and are vigorously guarded and cared for by both male and female (Ref. 44091).
