The African Knife Fish can reach up to 12 inches (30 cm) in the wild, but aquarium raised specimens are usually smaller, reaching around 8 inches (20 cm). The uniform blackish gray brown body of the African Knifefish is flat and elongated with an arched back. It has a continuous fin along the underside formed by a joining of the caudal and anal fin. It is a graceful swimmer and this fin allows it to move both forwards and backwards. These fish have no dorsal fins.It has a large mouth and two short barbels used for hunting. When not hiding it will normally be seen swimming with its head down and barbels close to substrate hunting for food. The barbels help to locate food. Like other knifefishes, it is a nocturnal predator that also uses electrical fields to navigate and find prey.Its scales are very small giving them an almost scaleless appearance with the only break being the lateral line. The lateral line is this fishes most important sensory apparatus, It has nerve filled pits throughout which gives it the ability to swim in lightless waters by emitting electrical pulses. An interesting characteristic is its ability to emit a bell-like or barking sound, produced by ejecting air from its swim bladder.

The night gobblers. A few fish, in particular certain types of catfish and knife fish, are nocturnalscorpion fish predators. That is, they either hide or patiently cruise the aquarium during daylight hours, but hunt incessantly from the moment the lights go out. Any bite-size tankmates unfortunate enough to be in their paths promptly become midnight snacks. Popular "night gobbling" catfish include the Pictus catfish (sometimes called the "angelicus" catfish) and the Columbian catfish going by various names such as "high-fin bull shark," "silver shark" or "Columbian white tipped shark," both of whom have long, feeler-type whiskers to help locate their prey in the dark. Any fish that comes into contact with the whiskers is promptly seized, and if a suitable size, swallowed whole. All species of knife fish are predatory, and it is strictly a matter of mouth size versus prey size that determines which fish can be kept with them. A clown knife fish can easily inhale a fish up to about one-fifth its length, especially if the fish is a slender-bodied species like a danio or swordtail. Most other knife fish like the black ghost and African knives have smaller mouths, but can still slurp up a tetra or two. Knife fish hunt by sight, and have specially adapted eyes that improve their night vision. Six African knife fish share this wooden hidey-hole. Schoolers: African black knife fish school together. They get along with their own species – unlike most knife fishes. They get along fairly well with other larger fishes. They love smaller fishes like tetras. I bought my black ghost knife when it was 1 inch. It is now 6 inches. Its tank mates are 4 silver dollars, pinkish Chinese algae eater, brown African knife fish. They all get along just dandy probably because their sizes are close. My BGK absolutely loves frozen blood worms. It also likes high protein pellets, frozen brine shrimp. I would like to give it live blood worms but its hard to find in this area. I saw a tank with a dozen BGK. They seem to be over active with each other swimming around at different angles back and forth. When they fight they bite each others tails. I don't recommend putting more than one. I clean my tank once a week. They do seem to appreciate quality water conditions. From: JeffI've kept three types of knifefish,; clown knife, black ghost knife, and african knifes. All were pretty peaceful, heck when I was first starting out my black ghost used to get attacked by my bumblebee gobies.
