BICHIR

The bichir, also known as Polypterus, is a unique and ancient freshwater fish species prized for its primitive appearance and fascinating behavior. Belonging to the family Polypteridae, bichirs are often considered living fossils, as their lineage dates back over 100 million years. These elongated, eel-like fish are native to the freshwater rivers and lakes of Africa.

Bichirs have a distinctive prehistoric look, with long, cylindrical bodies covered in tough, rhomboid-shaped ganoid scales, providing armor-like protection. They possess a series of dorsal finlets that run along their back, giving them a spiny, segmented appearance. Their coloration typically ranges from olive green to brownish-gray, with darker markings, allowing them to blend seamlessly into their environments.

One of the most striking features of bichirs is their ability to breathe both through gills and via a specialized swim bladder that functions like a lung, enabling them to survive in low-oxygen waters or even spend short periods outside of water. This dual respiratory system gives them a high degree of adaptability.

Polypterus species are carnivorous, feeding primarily on smaller fish, crustaceans, and insects. They have a slow, deliberate swimming style and are often seen resting at the bottom of aquariums or rivers. Despite their somewhat intimidating, dragon-like appearance, bichirs are generally peaceful fish, though they can exhibit predatory behavior toward smaller tank mates.

Their ancient lineage, striking features, and hardy nature make bichirs popular in the aquarium hobby, especially among enthusiasts of unusual or exotic fish species.
