Black Ghost Knifefish are very unique and interesting fish. Knifefish have the ability to produce a weak electrical current that they use for navigation and hunting. These fish are black in color, and have an anal fin that extends almost the entire length of the body. The tail is small and thin, and there is no dorsal fin. As their name suggests, knife fish are knife-shaped.
They are slow, graceful swimmers. Choose tankmates that are not nippy or inclined to chase the fish as it will not be able to swim quickly enough to get away. Even though they are peaceful fish it is not recommended that you keep them with smaller fish, as the knife will sometimes harass them.
Be sure to provide a cave or tube that allows the knife to hide. They are secretive fish and will become stressed if unable to find a secure hiding place. They are sensitive to poor water quality, and so require excellent filtration and regular aquarium maintenance.

Meh
by Corey. C
had one of these in my old tank, it was a cool fish..when you saw it... I maybe saw it out 4 times in the almost year I had the tank set up. It had a place to hide which it took full advantage of. Even with non-aggressive tank mates I still never saw it.
Good fish

This fish is nocturnal. You will almost never see it during the day time, but when the lights go off, it will become very active.This is a very unusual and cool fish to keep. Never put this fish with small community fish in the same tank because it will eat any fish that will fit in its mouth.
