Comments: The species was collected an altitude of about 810-1065 m.a.s.l.  The streams narrow (about 3-5 m width) and shallow (about 0.25-1.5 m deep) and the bottom was formed of small to medium-sized rocks, loose stones, gravel and sand. The water in the collection site was clear, cold (16.6°C-19.5°C), highly acidic (pH 2.78-2.87), poorly conductive (µs/cm 0.013-0.014), highly oxygenated (5.91-13.05 mg/l OD) and moderate to fast flowing.  Vegetation found at the margins of the stream, which shadows a wide portion of its bed.  Associated species captured in the stream includes <i>Astyanax rivularis</i>, <i>Neoplecostomus franciscoensis</i>, <i>Trichomycterus macrotrichopterus</i> and <i>Characidium fasciatum</i> (Ref. 92077).
