Tiger Bichir – Add a Bold Patterned Armoured Predator to Your TankTiger Bichir shows strong dark bands across its elongated body that resemble tiger stripes on tough overlapping scales. This Polypterus species breathes air through lungs and walks along the bottom using pectoral fins. Brisbane keepers choose these fish for their rugged look and hardy constitution. Their predatory habits demand large setups and careful companion selection.Size and LifespanGrows to around 60 cm in suitable aquariums, so plan for plenty of room as it develops. They regularly live 15–20 years when water stays clean and feeding remains consistent. Steady maintenance keeps them active for many years.Ideal Tank SetupChoose a tank of at least 500 litres to support its adult size and activity. Use smooth gravel or sand substrate, add large driftwood logs, rocks, and robust plants for cover. To replicate its natural habitat, create open bottom zones and fit a secure lid to prevent jumps. Maintain pH 6.5–7.5 and temperature 26–28°C with strong filtration and regular partial water changes.Compatible Tank MatesBehaves calmly toward large peaceful fish that match its size. It treats smaller species as food. Suitable tank mates include big plecos, robust catfish, large cichlids, and other heavy bottom dwellers. Avoid small fish, invertebrates, or anything that could become a meal.Diet and FeedingProvide with meaty carnivorous foods to satisfy its hunting nature. Frozen prawns, earthworms, bloodworms, and large sinking pellets serve as staples. Offer bigger portions as it grows. Feed every other day in the evening when it hunts, and remove any uneaten food promptly.Breeding and Behaviour of Tiger BichirLays eggs on the substrate during occasional captive spawning attempts. These fish patrol the bottom at night, surface for air, and move deliberately during low light. They rest under cover when bright and emerge boldly in dim settings. Large tanks with hides encourage typical foraging and reduce tension.Species OverviewSpecies – Polypterus sp.
