The aquariums come in varied volumes, ranging from as small as a glass bowl to a large public aquarium that holds an entire ecosystem. Here are some of the biggest aquariums in the world.

The Chimelong Ocean Kingdom

The Chimelong Ocean Kingdom boasts of a water volume of 12.9 million gallons. It is not only the largest aquarium in Asia but also in the world.
