Inhabits shallow sandstone bedrock rapids with abundant attached macrophytes, including a representative of the Podostemaceae, a representative of the Eriocaulaceae(Rhondonanthus capillaceus), and a third species with long grass-like leaves (Ref. 94269).

It differs further by its large adult body size (max. = 85.5 mm SL), and by having a tan body base color with a dark midlateral stripe that originates on the upper lip and continues posteriorly to the base of the middle caudal-fin rays, a gray to dark-black dorsum with two horizontal rows of small light spots formed by aligned light-colored scale centers, a dark humeral spot, up to 15 irregular black bars that extend from dorsum to lower sides, a light opercular margin, and fins that are uniformly dusky. Several cranial, vertebral, and swim bladder characteristics make this species distinct from other congeners (Ref. 94269) Lujan, N.K., H. Agudelo-Zamora, D.C. Taphorn, P.N. Booth and H.
