What a waste... He could have kept such cooler predators than groupers.... Dont get me wrong there are some cool groupers, but a 20,000 gallon tank for groupers is just stupid!
Just think of the Sharks he could have had. He could have had anything from a very small school of hammer heads to thresher sharks. Hell!!! he could have had dolphins for the price it would cost to feed a bunch of groupers. Hahahaha, But they are mammals and not as cool as sharks.
