Black Ghost Knifefish

Black ghost knife fish (Apteronotus albifrons) are a tropical freshwater fish that have been steadily growing in popularity over the years. This is mostly due to their incredibly unique appearance that makes them stand out in any tank. They get their name from two sources. The “black knife” portion comes from the obvious resemblance these fish have to a blade (especially if you think of the white rings on their tail as a handle). The “ghost” piece of their name originates from the local belief that ghosts of the dead occupy the bodies of these fish.
