While it doesn't seem like it, but the majority of Sea Life Aquarium is really one big tank which includes this hallway walk.
My favorite was the sea turtle. He was a rescue after an accident with a boat down in Florida.
He has to have a weight on his back so he can swim up and down with control.
They also offer a behind-the-scenes tour and you can see the top of the tank which I think they said it was over 40 or 50 feet tall.
