Adults prefer large rivers but is also found in large lakes and dams (Ref. 52193). They graze on algae and `aufwuchs' from rocks (Ref. 7248, 52193). From October to December in Lake Moëro, the adults gather and migrate to the spawning grounds; they go up the Luapula River up to the foot of Johnston Falls where they undergo one massive spawning between January and March. This massive spawning of short duration is known as kapata in the Luapula-Moëro system and in the tributaries of the Luapula. This species is intensely fished and caviar is produce from eggs collected during migration from Lake Moëro to Luapula River (Ref. 26190).
