i put other because you didn't include SA and CA as a choice. when no dought a lot of south and central american fish get 12"+ now those are the true monsters
monster fish should be anything over 16"'s and prehistoric looking , the keepers should be those crazy people with 5 or more tanks and trying to get bigger to house those massive fish. one more note a mfk'er is one who definitly takes care of their fish and loves too see the wow factor come over peoples faces when they see your tanks for the first time.
Try telling that to the bloke that got taken off the beach just down the road from where i'm staying in Perth a few weeks back from a Great White. All they found of him were a few scraps.
IMO, Great Whites can kick a whale sharks arse any day.
