The Georgia Aquarium in Atlanta, Georgia in the United States should and is on every aquarists bucket list to visit. You will often hear some people say that it has the largest aquarium in the world. However, this information is outdated.

They have an impressive 10 million gallons of water but their biggest aquarium only holds closer to 6 million gallons of water. Impressive, but it pales in comparison to Ocean Kingdom in China.

It has to be said that when it opened in 2005 it was the biggest single aquarium in the world right up until 2012.

The aquarium was mainly funded by the Home Depot owner Bernard Marcus. He is said to have donated $250 Million Dollars to build and stock this impressive aquarium which is open to the public.

The aquariums main attraction is a Whale Shark and this is the only aquarium outside Asia to house one. They also have an impressive collection of 700 species of fish and other sea creatures.

This has to be on everyone’s list to visit and will be in the TOP 10 PUBLIC AQUARIUMS for a very long time.

Visitors to the Moscow Aquarium will find it on Chistye Purdy. Situated in the city center, it is easily found and handy for public transport.

The best part of Oceanarium is a huge tunnel aquarium. This tunnel gives you an amazing view of the aquarium from all sides. You can often see divers cleaning the acrylic tunnel and also hand-feeding the fish.

The tunnel is made from super strong acrylic glass. It is 12 centimeters thick and there are two of these, each with 500 thousand liters of ocean water. 

Again, this is nowhere near the size of some other aquariums. However, it definitely has one of the best underwater tunnels.

The cost to visit is very reasonable when you compare it to some of the others and is on average around 100-300 rubles and the aquarium is also open 7 days a week.

This is one for children and adults alike. It is part of the Walt Disney Resort located in the Epcot Centre. This impressive facility has several exhibits dedicated to Ocean Marine Life.

This aquarium underwent a massive overhaul in 2003 when it was then called ‘ The Living Seas’. As a result of the popularity of ‘Finding Nemo’ Walt Disney resort invested millions of dollars in a total refurbishment of the park.

Not the biggest aquarium by any measure but in my opinion one of the best.
