The African Knifefish is a large carnivorous predator. Their bodies are
built in the usual Knifefish shape; stocky build with a very long-based anal
fin. The "tail" of this fish resembles a sword blade, hence its common name
of Knifefish. This particular Knifefish lacks a dorsal fin.
A large tank is required to for this fish to thrive as an adult. Juveniles
may be kept together but as adults they may fight. A heavily planted
aquarium is recommended with plenty of swimming space. Floating plants
should be used to subdue the lighting, as Knifefish are nocturnal. Being
nocturnal, they should also be fed after the lights are turned off. These
fish often make "clicking" sounds which can be heard when netting the fish.
African Knifefish are voracious predators that need meat in their diet.
Worms, beef heart and fish are all relished. Live foods are recommended.
These fish appreciate a slightly acidic to neutral pH; around 6.2-7.0 with
soft water at about 5 dGH. A general temperature of 72-82 degrees F will
suffice.
Little is known about the breeding behavior of this fish. Females lay up to
200 tiny eggs which hatch shortly. Sexing is said to be impossible. |
