A small number of freshwater fish cyprinids and catfish (which are bony fish and thus quite unrelated to sharks) are also commonly called "freshwater sharks", "sharkminnows" or simply "sharks", particularly in the aquarium fish trade: Balantiocheilos melanopterus – Bala shark, tricolor shark, silver shark; Epalzeorhynchos – typical ...
