Diet
According to Wikipedia, Polypterus delhezi is entirely carnivorous and hunts small fish, insects, worms, shrimp, prawns and mussels, locating food by smell rather than sight.
Compatibility
The species is semi-aggressive and bottom-dwelling. It can share a tank with robust companions such as larger Synodontis and mid-sized cichlids, but small fish may be eaten.
