The ghost knifefishes are a family (Apteronotidae) of knifefishes.
They are distinguished from other gymnotiform fish by the presence of a caudal fin[?], and can be found in the neotropical[?] regions of South America.
The Black ghost knifefish[?] (Apteronotus albifrons) and Brown ghost knifefish[?] (Apteronotus leptorhynchus) are readily available as aquarium fish.
A number of additional species have been discovered recently, and many more are expected to be found.
