An unusual but popular large-growing oddball. Knifefish are typically found in four different families of fish, Notopteridae (Featherbacks), Apteronotidae (Ghost Knifefish), Gymnotidae (Naked Back Knifefish) and Gymnarchidae (the Aba Aba).
They are only found in freshwater and primarily nocturnal hunters of small fish and invertebrates. They can give off a mild electrical charge which they use during hunting to stun their prey.
