RTC mine killed without remorse any fish in his aqaurium, smaller, or larger. Also they can smash straight through the side of your tank. A big one could more than likely kill you with his pectoral spines if they are not blunted. Not to mention that a large specimen has a skull that's over 3/4 inch thick solid bone. Not saying that it would last against all of the other fish mentioned, just saying it is an extremly powerful fish.
