I got to the Atlanta Aquarium and it was amazing. I snapped a couple pics with my iPhone. This is a must see if you get in this area.
This is from the main tank that contain 6 million gallons of water, the window is 20 x 60 feet and 2 feet thick.
The big spotted fish is a Whale Shark and at 25' they are about 1/2 what they can reach in the wild
The Manta Rays are my favorite, they must be at least 10 ft across. From what I understand these are the only captive Mantas in the world
