Comments: Found in streams characterized by relatively rapid water running over rocky and sandy substrates with high transparency.  Occurs syntopically with <i>Bryconamericus emperador, <i>Astroblepus sp., <i>Pimelodella sp. and <i>Characidium sp.  Feeds on adult and larval insects, nematodes, isopods, and unidentified arthropod fragments.  The presence of  autochthonous and some allochthonous items in the guts suggests that this species is insectivorous with considerable plasticity in its diet (Ref. 98056).
