Polypterus polli
A small grey to dark brown bichir from the middle and lower Congo. FishBase records a maximum of 32cm SL. Described by Gosse in 1988, it was long treated as a subspecies of P. palmas.
Polypterus polli is a small polypterid from the middle and lower Congo basin. FishBase records a maximum of 32.1cm SL, 5-7 dorsal finlets and an upper jaw slightly longer than the lower. The body is cylindrical and grey to dark brown with faint mottling. Described by Gosse in 1988, it was long treated as the subspecies P. palmas polli, so museum specimens and older literature still carry the subspecific name. It stays small for the genus and does not need a huge tank, but FishBase publishes no temperature or pH figures for it and Seriously Fish has no profile, so those numbers are omitted here. 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 and it is not listed by CITES.

Meaty live and frozen foods such as prawns, earthworms, mussel and lancefish
Small for the genus at about 32cm SL when adult. Favour floor space, arrange driftwood and smooth rocks over sand for cover, and fit a gap-free lid, as it escapes readily.
FishBase publishes no temperature, pH or hardness figures for this species and Seriously Fish has no profile. Beyond its being a tropical freshwater demersal fish nothing can be verified, so no numbers are given here.
It swallows anything small enough but is otherwise fairly peaceful. Other Polypterus, Synodontis and medium to large characins suit it. Being small itself, it should not share a tank with big predators.
Carnivorous and often refuses dried food. Offer prawns, earthworms, mussel and small fish, live or frozen. As a nocturnal species it feeds most reliably after lights-out.
No captive spawning could be verified. In congeners the male cups the eggs in his anal fin, fertilises them and scatters them among vegetation.
It breathes air and will drown if it cannot surface. Published husbandry is thin, so follow general bichir practice and watch the fish closely. 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 average lifespan of Polli Bichir is 8-12 years. With proper care and nutrition, they can live a long and healthy life.
Polli Bichir typically reaches Up to 32cm SL as an adult. Size may vary depending on care conditions and individual genetics.
Polli Bichir feeds on: Meaty live and frozen foods such as prawns, earthworms, mussel and lancefish. Aim for a balanced diet with appropriate feeding frequency.
