Mantis Shrimp can punch as hard as a bullet, can break aquarium glass and can create a cavitation bubble hotter than the sun.

You usually have to special-order mantis shrimp. It's easy to accidentally get a pistol shrimp when you asked for a peppermint; they look similar.
Yep. Any fish you put in the tank would disappear soon after.
