I think my husband and I have been to almost every major aquarium along the east coast and a few out west, so it's pretty hard to impress me with an aquariem. That said, I have to say that the Chattanooga Aquarium was very impressive. It's actually 2 aquariums - a fresh water and salt water. I loved the fresh water one because it was very different and nice how they tied in the local eco-system. We had a great time, and it is definitely worth the cost of admission!
