Found in strong-flowing rocky stretches of larger perennial rivers (Ref. 52193). It grazes algae and `aufwuchs' from rocks and firm surfaces including the backs of hippos, leaving characteristic tracks (Ref. 52193). Migrates upstream in swollen rivers to breed (Ref. 7248, 52193). Can occur as either sail-fin or normal varieties (Ref. 4967).
