Comments: Found in small, gently flowing, low-conductivity clearwater terra firme forest and savanna streams, and in static leaf-litter choked blackwater streams and swamps in <i>Mauritia</i> palm swamps.  Most specimens in streams were observed sheltering in submerged and marginal aquatic vegetation growing in sandy beds, and those in <i>Mauritia</i> palm swamps were collected from dense leaf litter banks and root mats.  Sympatric and syntopic with <i>Brachyhypopomus bullocki</i>, <i>B. brevirostris</i>, and <i>B. sullivani</i> in the type locality region.  Food items food in the stomach contents were aquatic insect larvae and other small aquatic invertebrates (Ref. 116763).
