Polypterus retropinnis
A small bichir speckled over a dark brown body, from the Ogowe and Congo basins. FishBase records a maximum of 34cm SL. The specific name refers to the rearward position of its dorsal finlets.
Polypterus retropinnis is a small polypterid of the Ogowe and Congo basins in Central Africa. FishBase records a maximum of 34cm SL and 7-9 dorsal finlets, and places it close to P. mokelembembe, P. polli and P. palmas. Fine speckling covers a dark brown body, and Seriously Fish notes the alternative name Speckled Bichir. That site gives 25-28C, pH 6.0-8.0, 5-25 dGH and a 120 x 45cm base of about 205 litres. Populations once reported from West Africa belong to the former subspecies P. retropinnis lowei, now regarded as a synonym of P. palmas. Nocturnal and guided by smell, it eats any fish that fits in its mouth, and because the swim bladder works as a lung it must be able to reach the surface. The IUCN rates it Least Concern.

Seriously Fish suggests a 120 x 45cm base of about 205 litres. Build cover from driftwood and smooth rocks over sand while leaving open floor, and fit a lid, as it slips out of any gap.
Seriously Fish gives 25-28C, pH 6.0-8.0 and 5-25 dGH. It tolerates a wide range, but a meaty diet fouls water, so keep filtration and water changes generous.
It swallows anything small enough but is otherwise fairly peaceful. Other Polypterus, Synodontis, Datnioides, knifefish and medium to large characins suit it; avoid big predators, since it stays small.
Carnivorous and often refuses dried food. Offer prawns, earthworms, mussel and small fish, live or frozen. Its sight is poor and it hunts by smell, so deliver sinking food to the bottom.
Captive breeding has not been recorded and is presumed to follow congeners. It spawns in the rainy season in the wild, the male cupping the eggs in his anal fin, fertilising them and scattering them among plants; hatching takes three to four days.
It breathes air and will drown if it cannot surface. Close congeners look similar and are often mislabelled, so check the number and position of the dorsal finlets when buying. The IUCN rates it Least Concern and it is not listed by CITES.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for West African Bichir is 25〜28℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of West African Bichir is 8-15 years. With proper care and nutrition, they can live a long and healthy life.
West African Bichir typically reaches Up to 34cm SL as an adult. Size may vary depending on care conditions and individual genetics.
West African Bichir feeds on: Meaty live and frozen foods such as prawns, earthworms, mussel and lancefish. Aim for a balanced diet with appropriate feeding frequency.
