Comments: This species is mainly in pools and lentic stretches of smaller streams with muddy or sandy bottoms. Some specimens were collected in pools between rock-gardens in the Iguazú main channel (Pasarela a Garganta del Diablo and pasarela a salto San Martín) and are ecologically very similar to the small tributary streams with similar stony substrates and muddy bottoms (Ref. 123557).
