ATLANTA (AP) - The world's largest fish tank has hit another
milestone.

The Georgia Aquarium welcomed its 10 millionth guest Thursday,
less than four years after the downtown Atlanta attraction opened
its doors. The lucky guest was Annette Kalber of Atlanta, who was
visiting with her mother, sister, niece and nephew.

She got a free dive in the 6 million gallon Oceans Voyager tank,
free airline tickets and other goodies.

The aquarium is home to more than 8 million gallons of tanks,
featuring the only whale sharks outside of Asia. The attraction is
the only aquarium in the world to let visitors dive with the four
whale sharks, the world's largest fish.

The attraction also plans to open a dolphin exhibit in 2010 that
will include shows and conservation research.
