Comments: Found in abundance in tributaries of the rio Aripuanã, such as igarapé do Aeroporto and igarapé Genipapo, clear water creeks two or three m wide and up to 0.6 m deep, with forested margins and sandy bottoms where fallen trunks, branches and vegetal detritus were abundant.  Collected using deep nets and by displacing the submerged debris, the natural hiding-places of the species.  Feeds on fish, various insects as well a scorpion and a crustacean (Ref. 87314).
