Tetraodon schoutedeni is a freshwater pufferfish native to the Congo Basin. This farmed strain is more robust and better suited to aquariums than wild specimens.

Known for its curious and interactive behaviour, it quickly develops a relationship with its keeper. Despite its small size, it remains a territorial fish requiring a suitable tank.

Behaviour and maintenance

• Territorial – keep alone, in pairs or in structured groups
• May nip slow-moving fish or fish with long fins
• Very intelligent and active

A well-planted aquarium with plenty of hiding places is essential to limit stress and conflict.

Feeding

Specialised carnivore

• Snails (essential for tooth wear)
• Artemia, bloodworms, krill
• Various frozen foods

A rich and varied diet is essential to prevent excessive tooth growth.

Water quality

• Temperature: 24–28 °C
• pH: 6.5–7.5
• GH: 5–12 °dGH
• KH: 3–8 °KH

Prefers stable, well-filtered and slightly aerated water.

Decor and environment

• Densely planted aquarium
• Numerous hiding places (roots, rocks, plants)
• Sandy substrate recommended

Avoid cohabitation with shrimps and small peaceful fish.

Care guide

AquaBota tip

Maintain a small colony of snails in an additional tank to ensure a regular supply for natural tooth wear. A structured tank with visual territories greatly reduces aggression.
