An Aquarium Tunnel is the most effective way to allow people to be underwater without actually getting wet. The view of fish and other aquatic wildlife from underneath is the most unique and unnatural view available. There is something very ominous about a shark swimming overhead less than three feet away.
The Aquarium Tunnel can be used both in freshwater and saltwater exhibits. Even open water tunnels have been constructed. Such a tunnel consists of acrylic panels, which are arched in large ovens, in order to form these magnificent overhead tanks. Aquarium tunnels can be of 180 degree angle, rectangular or of different shape.
