Etymology: Satanoperca: Taken from the prince of darkness. Hube liked to name cave fishes with diabolic names based on the idea of hell being underground + Greek, perke = perch (Ref. 45335).
Eponymy: Named after the devil, and referring in the case of the blindcat to the species’ underground habitat. Günther’s use of a name meaning ‘Satan perch’ for the cichlids was probably inspired by Heckel (q.v.) having named a species as ‘Geophagus daemon’. (Ref. 128868), visit book page.

Inhabits streams and lagoons with sandy to muddy bottom. Forages by plunging its protrusible mouth into the sandy or muddy bottom, filling it with sediment, and sorting out food inside the mouth. The bulk of the mouthful is expelled through the opercular openings and the
mouth, producing a cloud of sediment (substrate sifting). This feeding mode leaves a series of pits and mounds on the bottom. Feeds on insect larvae, crustaceans, plant debris and loose scales (Ref. 40396). Discourages piranha attacks by watching the predator, a tactic used when 2-5 fish feed in groups and the individuals take turns as the "watchman". Confronts an approaching piranha by charging towards the predator with an open mouth and erect dorsal fin (Ref. 9080).
