Inhabits lentic waters formed by the water table inside the caves, varying from large, partially illuminated lakes to isolated pools. Mainly solitary. Observed swimming up to about 35 m depth, but it usually aggregates between the surface and 10 m. Reported to show preference for substrate, concentrating in the rocky walls. Strictly a carnivorous species which feeds on invertebrates found near or on the bat guano (Ref. 86271). Bockmann, F.A. and R.M.C.

Differs also from Rhamdiopsis microcephala by its epiphyseal branches of supraorbital laterosensory canals not fused to each other, each one bearing its own pore, the s6 pore, and basal third of the posterior border of the adipose fin connected with the dorsal fold of caudal fin, leaving a large, almost complete free posterior lobe (Ref. 86271).
