The Bicher fish (often referred to as Bichir) is a type of ancient, freshwater fish native to Africa. It belongs to the family Polypteridae and is known for its distinctive appearance, with a long, cylindrical body, armored scales, and multiple dorsal finlets. Bichirs are considered “living fossils,” as they have existed for over 300 million years. They are typically nocturnal and have a unique respiratory system that allows them to breathe both through gills and lungs. Bichirs are carnivorous, feeding on small fish, invertebrates, and other aquatic animals. They are popular in aquarium settings due to their intriguing look and relatively easy care.
