Polypterus delhezi

Polypterus delhezi is a medium-sized bichir species admired for its bold vertical markings, armored body, and primitive appearance that strongly reflects the appeal of ancient fish. Its calm bottom-dwelling movements, small dorsal finlets, and solid ganoid scales give it a distinctive presence in the aquarium, making it especially attractive to aquarists who enjoy prehistoric-looking predatory fish. This species is generally hardy, but it may prey on small fish or shrimp that fit into its mouth, so tankmate selection and adequate bottom space are important for stable long-term care. Because Polypterus delhezi is an air-breathing fish that may explore openings around the water surface, maintaining clean water, providing hiding places, and securely covering the aquarium are essential points for keeping it safely and comfortably.
