Comments: Collected from a 0.5 m deep, small, clear water stream with a sandy bottom at an elevation of approximately 3500 m.  The stomachs of two specimens contained dipteran larvae (Chironomidae and Ceratopogonidae), filamentous algae, and sand indicating that the species feeds, at least in part on autochthonous benthic macroinvertebrates (Ref. 37038).
