The Georgia Aquarium received a certificate from the Guinness World Record naming it the largest aquarium in the world.
The Georgia Aquarium is officially the world's largest fish tank.
Alistair Richards with Guinness World Record in London, visited the downtown Atlanta attraction Sunday and presented aquarium President David Kimmel with a certificate naming it the world's largest aquarium. The attraction, which opened in 2005, holds more than 8 million gallons of water in its exhibits.
That includes the stunning 6-million-gallon Ocean Voyager tank. A new dolphin exhibit slated to open in the fall adds another 2 million gallons, cementing the title.
Aquarium spokeswoman Meghann Gibbons said the attraction has held the world record since opening in 2005, but this is the first visit from a Guinness official.
