Senegal Bichir – House a Tough Armoured Survivor in Your Big TankSenegal Bichir carries a long, snake-like body covered in tough scales that give it an ancient look. This Polypterus senegalus breathes air through paired lungs and moves across the bottom using sturdy pectoral fins. Experienced keepers in Melbourne pick these fish for their resilience and unusual habits. Their predatory ways require thoughtful tank planning and large companions.Size and LifespanGrows to around 60 cm when kept in proper conditions, so plan ahead for substantial space. They often live 15–20 years with steady water quality and suitable feeding. Regular checks help them stay strong over decades.Ideal Tank SetupSelect a tank of at least 400 litres to give it room to roam and grow. Cover the floor with smooth gravel or sand, then place large rocks, driftwood, and heavy plants for hiding. To replicate its natural habitat, add open bottom zones and a secure lid to stop escapes. Maintain pH 6.5–7.5 and temperature 26–28°C with powerful filtration and frequent partial changes.Compatible Tank MatesSenegal Bichir stays bottom-focused and tolerates large peaceful fish that share its space. It views small tankmates as food. Suitable tank mates include big plecos, robust catfish, large cichlids, and other similarly sized bottom dwellers. Keep away from small fish, shrimp, or anything that fits in its mouth.Diet and FeedingFeed meaty carnivorous items to match its hunting instincts. Frozen prawns, earthworms, bloodworms, and sinking carnivore pellets work well. Offer larger pieces as it grows. Feed every other day in the evening when it hunts, and clear leftovers to keep water clear.Breeding and Behaviour of Senegal BichirLays eggs on the substrate or among plants during rare captive spawning. These fish patrol the bottom at night, surface for air, and walk on fins during the day. They rest under cover when lights are bright and emerge confidently in dim conditions. Spacious tanks with hides support natural activity and reduce stress.Species OverviewSpecies – Polypterus SenegalusCommon Name – Dinosaur Fish, Dinosaur BichirOrigin – Africa (Niger River, Nile River)Diet – CarnivorouspH Range – 6.5 – 7.5Temperature – Tropical 26°C – 28°CBreed Type – Egg LayerCurrent Size – Approximately 12-15 cmMax Size – Approximately 60 cmTank Size – Minimum 400 litresFAQs about Senegal BichirWhat size tank is ideal for Senegal Bichir?
