I think these fish are really cool as well. :)

BGK's get very big; they usually get 16"-20", but some can actually reach 24". They can be housed in a 55G tank when they are young, but should eventually be moved into a larger tank.

Your gonig to want to have floating plants, because they are very shy and sensitive to light. They need a lot of hiding spots, and are nocturnal as well.

They are carnivores, and frozen blood/black worms are a good diet. They should take freeze-dried as well, and like live worms as well.

They are peaceful to most communtity fish. They will establish a territory and chase other fish away, but they should keep them alone for the most part. Only 1 BGK should be in a tank.

they are great fish, i have 2...if you think that they will grow too big for your liking then check out the brown ghost knife. its the same fish only brown and doesn't grow as big.

good luck :D

After looking through all of my books and wearing out google, I cannot find any reference to a brown ghost knife. The closest I could find was a fish, Apteronotus leptorhynchus. This is not the same fish as a black ghost knife, Sternarchus Albifrons. Have I missed something? Has there been a color morph discovered? That being true, they would still be comparable in size.

Not even from the same continent. Not the same fish then, obviously, eh?
