Polypterus mokelembembe
A bichir from the middle Congo basin, described in 2006, with the dorsal fin set far back. Fish imported as 'retropinnis' reportedly included this species, so identification needs care.
Polypterus mokelembembe was described in 2006. FishBase gives its range as the middle Congo basin in the Republic of the Congo and the Democratic Republic of the Congo, with a maximum of 26.7 cm SL and 142 g. It is named after Mokele-mbembe, a legendary creature of the Congo basin. Slender, with the dorsal finlets starting far back on the body, it closely resembles P. retropinnis, which also lives in the Congo basin. Before its description, fish imported as retropinnis reportedly included this species, and the names can still be confused; check the scientific name, origin and markings when buying. Like other bichirs it breathes air using part of its swim bladder. A nocturnal carnivore, it eats animal foods. Information on its care and breeding is still limited. It is only occasionally offered by Japanese specialist shops.
