Facultative air-breathing in the genus (Ref. 126274); Found in coastal areas of main river channel with bottom composed mostly by large boulders of sandstone with patches of sand and pebbles. Occurs in well oxygenated waters having moderate current speed, about 0.60 m s-1, water transparency of 1.5-2.40 m and conductivity of 50.9-59.6 μS cm-1 . Sympatric with Hypostomus commersoni, H. cochliodon,, H. uruguayensis, H. latifrons, H. ternetzi, H. luteomaculatus, H. microstomus, and H. boulengeri (Ref. 91776).
