Black Ghost Knife Fish are carnivorous and eat insects, small crustaceans and fish in the wild.

They will also eat small pellets, peas, earthworms and frozen community fish foods.

It is a peaceful fish that needs peaceful community tank mates. It is best not to keep them with small fish (<4cm) as they are predatory. Black Ghost Knife Fish should not be kept with their own species as they will show aggressiveness to their own kind in a small tank.

It can reach 60 cm in the right conditions and can live more than 7 years.
