Description
The Black Ghost Knifefish is a unique, nocturnal fish known for its electric organ used for navigation and communication. It has a distinctive black body with a white band on its back and tail, though the one in the image appears to be a juvenile or a variant with a reddish tail tip. These fish are fascinating but require a large, well-maintained aquarium with plenty of hiding spots.
