About African Lungfish

 

African Lungfish Protopterus annectens is one of the most popular types of fishes in the aquarium trade. These fishes are also famous with common names like the Marbled Lungfish and Leopard Lungfish.

African Lungfish belongs to the genus of Protopterus, a part of the Lepidosirenidae family. This exotic tank fish comes with a smooth body, having an elongated cylindrical shape.
