Description

The black ghost knifefish is a New World knifefish (Apteronotidae) from northern and central South America. The species has a velvety-black, elongate, knife-shaped body with two white rings on the tail and a white stripe on the head, and a long, continuous anal fin with which it swims undulating forwards and backwards; a dorsal fin is absent. It inhabits fast-flowing creeks with a sandy bottom. With a weak electric field it navigates in the dark and locates prey. As a nocturnal micropredator it eats insect larvae and small invertebrates. It is a popular aquarium fish and is harmless to humans.
