Comments
The fish shown and discussed on this page are called Knifefish, because their shape seems to resemble a knife.

Aquarium Knifefish belong to three groups that are not closely related to each other: (1) The Featherback Knifefish, (2) the Weakly Electrical Knifefish of the Neotropical Region, and (3) the Aba Aba Knifefish.

Featherback Knifefish
The Featherback Knifefish are called Featherbacks because of the small fin on their back that is said to look like a feather.

They are naturally found in Asia and Africa but not in South America.

The Featherbacks include the Clown Knifefish, the Royal Clown Knifefish, and several other Knifefish that are very rarely seen in aquarium.

Click here for more about these two species.

The African Black Knifefish is closely related to the Featherbacks, but the African Black Knifefish does have a fin on its back.

Click here for more about the African Black Knifefish.

Weakly Electrical Knifefish
The Weakly Electrical Knifefish of the Neotropical Area are found only in South America and Central America and not in Asia or Africa.

There are many Weakly Electrical Knifefish including the Black Ghost, the Brown Ghost, and a few other that are kept by aquarists.

Click here for more about Weakly Electrical Knifefish.

Aba Aba Knifefish
Finally, the third group of Knifefish contains only one member the Aba Aba, which is more closely related to the Arowana and the Arapaima.
