The imitator cory, Brochis imitator, long known as Corydoras imitator, is an armoured catfish endemic to the upper rio Negro basin in northern Brazil and southern Venezuela. It is one of several rio Negro congeners with an oblique dark bar along the dorsal surface of the body, a group that includes Hoplisoma adolfoi, H. burgessi and H. duplicareum. It inhabits pristine blackwater tributaries and flooded forest with tea-coloured water, very little hardness and a pH of 4.0-6.0.
