While the Georgia Aquarium is impressive, it has nothing on the world’s largest fish tank. The AquaDom, located in the lobby of the 5 star Radisson SAS Hotel in Berlin, holds 2.500 tropical fish enclosed in an 82 foot high Plexiglass cylinder. The fish tank can be viewed from every room on every floor of the swanky hotel. This fish tank gives new meaning to the term “sleep with the fishes.”
