If you’ve personally seen a 300-gallon fish tank up close you know how tiny it makes you feel.

However, the dimensions of commercially available fish tanks are nothing compared to the largest public aquariums found around the world.

Tank size does matter in these facilities, as some of them accommodate whale sharks, gigantic fish that may easily reach up to 30 feet in length (9 meters).

Each entry in the top 15 of the biggest aquariums in the world holds no less than 2,000,000+ gallons or of water, which is 7.5 million liters. Some of them are home to thousands of animal species.

What is the LARGEST Aquarium in the World?

Each of the aquariums listed below is made to keep an enormous number of animal species. For this reason, the water capacity of most of their tanks is in the millions of gallons.

Take a look at the largest aquariums in the world ranked by their gallon capacity:

You can even dive into the main tank along with an instructor and see some of the aquarium’s residents up close.

The creatively named “The Seas with Nemo & Friends” is a public aquarium that was previously known as The Living Seas, a world record holder until 2005.

This facility used to hold the record for the world’s largest public saltwater aquarium, right until the Georgia Aquarium opened doors and seized that title.

The Seas with Nemo & Friends has a total tank volume of 5,700,000 US Gallons of seawater, which equals 22,000 cubic meters.

The aquarium itself is part of a Ride event at the Epcot, an amusement theme park under the operation of Walt Disney World Resort located in Florida.

With its tank size of 5.7 gallons, it holds the 6th place in the rankings of the world’s biggest aquariums.

The gigantic Moscow Oceanarium is, evidently, located in Moscow, Russia.

It holds no less than 6.6 million gallons of total aquarium water, which makes it the 5th largest public aquarium worldwide.

It is relatively unpopular, given its total tank size and dimensions, but judging from the photos it is definitely worth visiting.

4. The Oceanographic Oceanarium – 11 Million Gallons

The Oceanographic also known as L’Oceanogràfic is the biggest large-scale aquarium in Europe. It is located in Valencia, Spain and the total water volume of its tanks is 11,000,000 US gallons or 42 million liters.

This European oceanarium has a separate tank of 1,800,000 US gallons that’s specially designed to harbor large marine animals such as rays and sharks.

There’s also another larger dolphinarium tank with a huge water volume of 6.9 million gallons.

Nevertheless, the Oceanographic is home to no less than 45,000 animals.

The facility also has impressive architecture, unique to water parks, as to be expected of the 3rd largest aquarium worldwide.

The giant Georgia Aquarium is situated in Atlanta, Georgia U.S. and holds no less than 11 million gallons of both fresh and sea water, which equals nearly 41,640,000 liters. The Georgia Aquarium is, therefore, the largest aquarium in the United States. The facility also held the title of the biggest public aquarium in the word for 7 years, until in 2012 it got surpassed by a bigger Asian aquarium.

Georgia’s public aquarium proudly welcomes more than 2.5 million visitors per year.

In October 2020, the facility expanded with a separate exhibit for sharks that added another 1 million gallons of water to its previous total tank capacity of 10 million gallons.

Up until then GA was the 4th largest in the world, but the new shark facility officially pushed them to number 3!

Anyway, this enormous public aquarium is not foolproof, as in 2007 two whale sharks died within its borders.

Author’s note: The sharks were imported from Taiwan, and were to be eaten if not purchased by the Georgia Aquarium.

With the two additions, the facility became home to 4 healthy whale sharks named Yushan, Alice, Taroko, and Trixie.

2. South East Asia (S.E.A.) Aquarium – 12 Million Gallons
