Comments: Found in the upper phreatic zone of a large karstic area (over 300 km2) including limestones
  and quartzites, which is connected to surface through caves.  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).
