FBname: Carmelitano catfish
Comments: Collection area with the water extremely clear (small characids readily observed) and
  well oxygenated. The stream was shallow (not exceeding 1 meter), and its bed was completely formed by rocks; light penetration was low during samplings. the reach, submerged tree roots and accumulated leaves and fruits (especially Fabaceae) formed some microhabitats for some species, notably Trichomycterus candidus and Cetopsorhamdia iheringi,  Specimens of this species were captured in environments that combined rocks (generally juxtaposed) and a more turbulent flow. The species is apparently demersal upon observation sampling. The species was collected with C. iheringi, Hoplias malabaricus, Knodus moenkhausii, Odontostilbe weitzmani, Oligosarcus argenteus, Pareiorhina sp., Psalidodon sp., T. candidus, T. septemradiatus (Ref.
