Puffers look really goofy, but they're nothing to laugh at when they've got a hold of your finger.

puffer fish. Those cute, cuddly, doe–eyed denizens of the deep tell it to this diver you are right they are bad boys pic from (http://floridakeystreasures.com/diving/puffer.shtml)

the meanest fish I ever had was a rainbow wolffish, the thing just killed everything, including cihlids easily twice its size. Grea fish for a one-fish tank, huge teeth and nasty look. they'll eat right out of your hands too (if you want to risk it)

Get a Fahaka Puffer...they are by far the craziest fish in the entire world... I use to feed my fahaka hermit crabs....he used to rip off there heads first...let them crawl around for about ten seconds and then they die and he eats the rest...hermit crabs are cool cuz they clib the plants and stuff to avoid the puffer...but the puffer is a helicopter there is no avoiding it
