How would you like it if another species put you on display in a box that allowed just enough space for you to turn at a completely foreign event where you had no idea what was going on, where the energy and noises were chaotic and these other creatures continuously check you out all day - taping on the box, making strange sounds, staring, pointing and so on?!
The Mandalay Bay Shark Reef brought a shark in a tiny aquarium to a VERY LOUD (as in huge truck horns constantly honking) children's event. A completely unacceptable environment for a shark.
Bad move, Mandalay Bay. Please leave these majestic creatures in the wild or at your facility that at least somewhat resembles their natural environment.
