The Black Ghost Knifefish is known from rapidly flowing creeks with sandy substrates. This nocturnal oddball is a micro-predator of insect larvae and small fish, and possesses a weakly discharging neurogenic electric organ and ampullary electro receptors that are distributed from head to tail. This means that the fish can not only sense electrical impulses, but can send them as well. These electrosensory systems are used mainly for electro-location, navigation, and communication, and are relatively weak as electric fish go, so pose no risk to the aquarist.
