The fish is all black except for a single white ring on its tail. It moves mainly by undulating a long fin on its underside. It will grow to a maximum length of 20 inches (50 cm centimeters).

The Black Ghost Knifefish natively lives in fast moving, sandy bottom creeks in a tropical climate. They prefer water with a 6.0 - 8.0 pH, a water hardness of 5.0 - 19.0 dGH, and a temperature range of 73-82 F (23-28 C). A nocturnal fish, they use an electric organ and receptors distributed over the length of their body in order to find insect larvae.
