Albino Bichir Care Guide - Aquarium Setup, Diet & Breeding

The Albino Bichir is a pale colour form of Polypterus senegalus, recognised by its creamy white to yellowish body, pink or reddish eyes and rows of small, diamond-shaped dorsal finlets. Its elongated, primitive-looking body and armoured scales give it a distinctly prehistoric appearance, which is why bichirs are often described as living fossils or dinosaur fish.

This species has a long, eel-like body, though it is not an eel. The paired pectoral fins are used for steering and slow movement, while the series of separate dorsal finlets can be raised when the fish feels alert or threatened. Its broad head and large mouth reflect its role as an opportunistic predator.

Albino Bichirs are generally calm, deliberate and most active from dusk through the night. They spend much of their time close to the bottom, investigating their surroundings with an excellent sense of smell. Individuals may rest motionless for long periods before making a sudden, purposeful movement towards food.

Like other bichirs, this species possesses primitive lungs and can breathe atmospheric air. This adaptation allows it to survive in warm, oxygen-poor or seasonally shallow African waters. It must be able to reach the water surface, and its unusual breathing behaviour is a central part of its natural history.

Although usually peaceful with fish too large to swallow, an Albino Bichir is still a predator and will consume smaller fish, shrimps and other suitably sized aquatic animals. Its slow, ancient appearance can be misleading: it is a capable nocturnal hunter that grows into a substantial aquarium inhabitant.

Polypterus senegalus is native to freshwater habitats across tropical and subtropical West and Central Africa, including parts of Senegal, Gambia, Niger, Chad and the Congo basin. It inhabits slow-moving rivers, floodplains, swamps and seasonal pools, where it often shelters among vegetation and submerged debris.

An adult Albino Bichir should have at least 280 litres, with a practical minimum footprint of about 120 × 45 cm; larger specimens and community groups need considerably more space. Use a secure, completely sealed lid because bichirs are powerful escape artists and may breathe at the surface. Provide a broad open bottom area with smooth sand or fine, rounded gravel, along with caves, sturdy wood, rockwork and robust plants for shelter. Keep the flow gentle to moderate, leave clear access to the surface, and avoid sharp decorations that could damage the body or delicate dorsal finlets. Maintain stable tropical freshwater conditions around 24–28°C and pH 6.0–8.0.

Up to 35 cm (14 in) in captivity, with females often growing slightly longer and heavier than males.

Albino Bichirs are carnivorous predators and should receive a varied diet of sinking, meaty foods. Good options include quality carnivore pellets, chopped prawns, mussels, earthworms, bloodworms, blackworms and suitably sized pieces of fish. Frozen foods are convenient and nutritious, while live foods can stimulate natural hunting behaviour but should come from reliable, disease-free sources. They usually feed most readily in the evening or after dark, and uneaten food should be removed promptly.

Suitable tankmates are robust, peaceful fish too large to fit in the bichir's mouth, such as large barbs, medium to large peaceful cichlids, suitably sized gouramis, larger characins and other calm bottom-dwellers. Avoid tiny community fish, juvenile tankmates, shrimp, small crayfish and ornamental snails, which may be eaten. Highly aggressive cichlids, fin-nippers and boisterous species that compete intensely for food are also poor choices. Albino Bichirs can be kept alone or with other appropriately sized bichirs when the aquarium provides ample floor space and hiding places.

Breeding Albino Bichirs is possible but uncommon in home aquariums and generally requires a mature, spacious setup with seasonal changes in temperature and water chemistry. A well-conditioned pair may spawn among dense plants or a spawning mop, with the male receiving eggs in his modified anal and caudal fins before scattering them. The eggs are small and should be separated from the adults, as both parents may eat them. Soft, slightly acidic to neutral water, gentle flow and abundant cover help encourage spawning, but raising the fry requires small live foods and careful attention to water quality.

Sexual differences are subtle. Mature females are generally broader-bodied and somewhat larger, while males usually have a thicker, more conspicuous anal fin that forms part of the reproductive structure. These differences are most reliable in fully mature fish and can be difficult to judge from photographs.
