The Black Ghost Knifefish is a member of the Apteronotidae family and the speckled knifefish group. It is considered a true bony fish. When properly cared for, the Black Ghost Knifefish can reach well over one foot in length. It possesses a weak electrical organ at the caudal peduncles which is used to locate food.It requires a minimum of a 150 gallon tank with excellent filtration.
It is generally timid and reclusive, preferring a fine-gravel-bottom aquarium with plenty of roots and rocks for hiding places, as well as subdued to dark lighting. To better appreciate this fish, many hobbyists will purchase a "ghost tube," a clear plastic tube that facilitates viewing during the day. Once accustomed to its surroundings, the Black Ghost Knifefish can become incredibly tame and trusting to the point of being hand-held. It does well with other, larger species of a peaceful nature, but may be aggressive towards those of similar or smaller size.
