The Black Ghost Knife is a large fish that has the ability to release a slight electrical current that it uses to navigate. It's eyesight is almost nonexistent, so it relies on it's electric navigation. This "electricity" is barely detectable to other fish, and so cannot stun you. They are nocturnal, so expect to see them laying on their side during the day, but this is just sleep, and they will come out as soon as the lights go out or food detected.

Tank Setup

The Black Ghost Knife can become hand tame, which makes it even more of a delight to an aquarium, but there should only be one per tank. Tankmates should not include any fin-nippers or large Cichlids. They should be provided with a heavily planted tank with plenty of rocky retreats and driftwood shelters.

Feeding

Black Ghost Knifefish must be fed a varied diet. This may include live foods, beefheart, shrimp pellets, snails, small fish and worms. Tubifex and Bloodworms are said to be a favorite. These fish are big eaters. If they are not properly nourished, they may hunt other fish in the tank. As always, live foods are beneficial. Black Ghosts are very quick at detecting the smell of food. Even when there are just a few pieces and the other fish have gotten to them, you can expect your Knifefish to be out immediately, zig-zagging and looking for it.

Water Chemistry

The water should be slightly soft with a pH of around 6.5-7.0 and a general temperature range from 72-80 degrees F.

Breeding

The black ghost knife fish is being bred successfully in Brisbane Queensland Australia.
