The type-locality where the specimens were collected from a clearwater river up to c. 3-6 m wide and 0.5-2.5 m deep, with preserved riparian vegetation, swift current, and sand, pebbles and dead leaves on the bottom. Several types of microenvironment were sampled exhaustively, but this species was captured only between root and subaquatic vegetation. Associated species sampled syntopically were Aequidens cf. rondoni, Erythrinus erythrinus, Hemigrammus skolioplatus, Hyphessobrycon hexastichos, H. melanostichos, Hasemania nambiquara, Hoplerythrinus unitaeniatus; and no other Gymnotiformes were collected with this species (Ref. 105010).
