These are tanks like we can only dream of. So take in these videos of the world's three largest aquariums (they do have sound) and dream away. They are spread out over three continents. If you ever get a chance to visit just one of them, take it. These videos are nothing compared to the real thing.
# 3 "Kuroshiro Sea" Okinawa Churaumi Aquarium (1.98 million gallons)
# 2 Dubai Mall Aquarium (2.64 million gallons)
#1 Georgia Aquarium (6.3 million gallons)
I do not own any of these videos. Credits are in the individual videos.
