I did see that coral display, it was very nice, actually used real live rock in it (I think).... I think that they probably have more gallons of saltwater there than freshwater though... once you get downstairs, a majority of the tanks are saltwater, like the tropical fish tank that is enormous when you first get into the saltwater section, and the shark tank, the lion fish tank, jawfish tank, giant crab tank, octopus tank, the 'ray tank, horseshoe crab tank........etc!
