Retropinnis bichir

The Retropinnis bichir, often characterized by its olive-green to brown coloration with a pattern of dark spots, is a distinctive species of Polypteridae from the freshwater systems of Central and West Africa. It features the elongated body and series of dorsal finlets typical of bichirs, contributing to its prehistoric appearance. This species can grow to a moderate size, making it a notable but not overly large specimen for aquarium enthusiasts. While it has a dedicated following, the Retropinnis bichir is not as widely known in the hobby as some of its relatives, partly due to its specific care requirements and relative rarity.
