Overview
The African Lungfish (Protopterus aethiopicus) is a living fossil — an air-breathing, eel-bodied giant whose lineage predates the dinosaurs. Intelligent, long-lived and genuinely interactive, it is one of the most extraordinary fish in the hobby, but its enormous adult size and powerful bite make it strictly a project for the experienced, well-equipped specialist.
Appearance & Identification
Elongate and smooth-skinned with thread-like paired fins, the African Lungfish can reach an immense 150cm and live for decades. It possesses true lungs and must breathe air at the surface to survive. Colour is a marbled grey-brown that pales on the belly, and adults develop a heavy, muscular body.
Aquarium Setup
This species needs an aquarium measured in thousands of litres — 3000 litres or more — with a soft substrate, minimal sharp décor and, crucially, a heavy, securely-clamped lid. Warm water (24–30°C) at pH 6.0–7.5 and powerful, robust filtration are essential. It must always be able to reach the surface to breathe.
Important
The African Lungfish reaches around 1.5 metres, has a powerful, bone-crushing bite and is best considered a single-specimen animal for expert keepers with pond-scale housing. It is not suitable for a normal home aquarium or a community setting.
Temperament & Tank Mates
Semi-aggressive to outright predatory, it will attempt to eat or bite almost any tankmate and can injure careless hands. For these reasons it is nearly always kept alone. It is, however, remarkably aware of its surroundings and often learns to recognise and respond to its keeper.
| Great tank mates | Best avoided |
|---|---|
| Best kept alone | Any tankmate small enough to eat |
| Fish that could be bitten | |
| Delicate or slow companions |
Feeding
A carnivore, it takes large meaty foods such as whole mussel, prawn, earthworm, fish fillet and quality carnivore pellets. Feed adults a few times a week rather than daily, using tongs to avoid its powerful bite, and never overfeed a fish that produces this much waste.

Expert Tip
Always feed with long tongs and keep the lid firmly secured — a lungfish is deceptively fast at the surface and both its bite and its escape attempts should never be underestimated.

I have a small group of long finned mountain minnows. So was delighted to be able to order ten of this variety to increase the genetics in my tank . The ones I recieved are healthy but it’s to early to give a verdict on wether they are of a long finned type since they are small currently.

100% success travel and "installation". Pleased with quality of purchase. The Siamese fighter a bit "shy" so have not yet seen him at his best yet but looking good. Happy customer. GG
