Both fresh and saltwater, predator, bigger than 3 ft, needs more than 150 gallons.
No, wait, I take it back... its Rosie O'Donnell!
It's a fish though.
I'm inclined to go with bderick and say bull shark. That was that whole fiasco in 1916 on the Jersey Coast with one getting up a creek and eating a few people. (There is a great book about that. I read it a few years ago so the title escapes me, but it's definitely a worthwhile read.)
