West African Bichir

The West African Bichir (Polypterus retropinnis) is a small member of the ancient Polypterus lineage, its dark brown body patterned with fine speckles. Native to the Ogooué and Congo river systems in Africa, it gets its species name from the way its small dorsal finlets cluster toward the rear of its back. Like other bichirs, it breathes air using a lung-like organ, periodically rising to the surface for a breath — a habit that gives it a distinctly prehistoric feel. Mostly active after dark, it often "walks" along the substrate using its paired fins. Generally calm and easygoing, some individuals grow comfortable enough to approach their keeper at feeding time, making this a rewarding species for hobbyists who enjoy close observation.

About West African Bichir

The West African Bichir is an ancient African fish from the Ogooué and Congo river systems, known for its dark, finely speckled body. This air-breathing, nocturnal species grows up to 34cm and suits intermediate keepers.

7 things to know before welcoming a West African Bichir

  1. 1Escape-Proof Your Tank

    Bichirs can squeeze through surprisingly narrow gaps and are known escape artists. Use a tight-fitting lid and seal any gaps around filter tubing or cords to keep your fish safely inside.

  2. 2Needs Access to the Surface

    This species has a lung-like organ and regularly rises to gulp air at the surface. Leave enough space between the water line and the lid so it can breathe comfortably.

  3. 3Be Careful Mixing Tankmates

    Fish small enough to fit in its mouth may be eaten, so choose tankmates of a similar size or larger. Since it is nocturnal and tends to hide, providing shelter will help it feel secure.

  4. 4Nocturnal by Nature

    It tends to stay still in hiding spots during the day and becomes active after dark. Provide driftwood or ceramic shelters so it has places to retreat and feel secure.

  5. 5Feeding Takes Patience

    Individuals may take time to accept prepared foods at first. Start with frozen bloodworms or similar meaty foods, then gradually mix in pellets as it becomes accustomed to feeding.

  6. 6Plan for Its Adult Size

    This species can reach up to 34cm in standard length, so a tank sized for a juvenile will quickly become too small. Plan ahead for its adult size when choosing an aquarium.

  7. 7Can Grow Comfortable With You

    While often shy at first, individuals may grow accustomed to their surroundings and approach the front of the tank at feeding time. This species rewards patient, hands-off keeping.
