Atlanta, Georgia is now home to the world’s largest aquarium, the Georgia Aquarium, holding upwards of 8.5 million gallons of water and 120,000 animals covering more than 500 species from 60 different habitats.

This AquaDom was built in one of Berlin hotels in 2003. It’s the biggest cylindrical acrylic glass aquarium in the world filled with 900,000 liters of seawater and 2,600 fish of 56 species. Two divers work full-time to clean this huge 25 meter tall aquarium! No wonder that AquaDom that has costed over 12 million euros is the main attraction in Berlin. I wouldn’t mind taking the build-in transparent elevator and exploring the sea world myself!
