When serious hobbyists use the term "aggressive tank" they are referring to fish that are not community fish in the accepted sense. Such fish have normal behaviours that preclude them from being in a normal community tank, although they may suit larger tanks of carefully-selected fish species as well as single species setups. Provided the tank is large enough to accomodate their individual traits, there will not be any tearing or shredding of other fish, though sometimes this is natural within a species regardless.
Rift lake cichlids generally are considered "aggressive," in fact almost all cichlids are. Other species include Serpae Tetra, Tiger Barb (and some other barbs), Red Tailed Shark, some of the Botia loaches, Red Bellied Pirahna, Bucktooth Tetra, Leaffish, and others.
