Polypterus senegalus

Polypterus senegalus is a unique freshwater fish known for its prehistoric appearance and lung-like structures that allow them to breathe atmospheric oxygen. They are robust, nocturnal, and prefer a tank with plenty of hiding spots such as caves and plants. They are carnivorous and should be fed a diet rich in protein with live or frozen foods like bloodworms, prawns, and small fish. They possess a primitive pair of lungs that enable them to survive in low-oxygen waters, leading to their resilience in captivity.
