African Lungfish – The Living Fossil of the Aquarium
(Protopterus annectens)
The African Lungfish is one of the most fascinating and ancient freshwater species available in the aquarium hobby. Known as a true “living fossil,” this incredible fish has remained virtually unchanged for millions of years. Its unique ability to breathe air through a primitive lung allows it to survive in oxygen-poor environments — even burrowing into mud and entering a state of dormancy during dry seasons.
With its elongated, eel-like body and distinctive mottled grey or brown coloration, the African Lungfish is a striking and unusual centrepiece for large aquariums. It is an intelligent and long-lived species, best suited for experienced fishkeepers who can provide the space and care it deserves.
