The Black Ghost Knifefish, as their name suggests, is entirely black except for two white rings on its tail and a white stripe on its nose that often extends along its back. Unsurprisingly, it is also the shape of a knife – it has no caudal or dorsal fin. … The electricity is produced by an organ found in the tail.
Approximate size 5cm
