10 Largest Aquariums in the World

The most common size for a home aquarium tank is probably 29 or 30 gallon, though some aquarists have constructed aquariums of many thousands of gallons. Public aquariums can be dramatically larger than any home aquarium. But only a few are big enough to make it to our list of largest aquariums in the world. The kind of aquarium that can hold whale sharks and manta rays. It takes a very large tank to hold these kind of aquatic creatures.

In order to compare these large aquariums we have looked at the size of their biggest tank (in gallons). Most aquariums have several tanks and the combined volume of water can be much larger but it is only the largest aquarium tank that is counted. So here’s a list of the largest aquariums in the world.

10Aquarium of Western Australia (0,8 million gallons)

  1. António Castanheira says

    Nº 5 in this list should be the Lisbon Aquarium – 1.35 million gallons of water.

  2. Stu says

    The Osaka Kaiyukan Aquarium has a total capacity of 10.9Mil… How come it didn’t make the list?? The main tank is amazing!

  3. says

    Thanks Stu. The largest tank of the Osaka Kaiyukan Aquarium is about 1,43 million gallons, so big enough to make it to this list.

  4. Melanie says

    I went to the Georgia Aquarium not knowing it was the bigest in the world. The place is amazing and very inspiring. I now am rethinking my major in school. If you are ever near Atlanta, you must visit this aquarium. You’ll love it and the price of admission is very low.

  5. The Truth says

    Someone already mentioned Lisbon Aquarium, 5,5 million liters main tank, and there’s also the North Sea oceanarium in Denmark, at 4,5 million liters (1,2 million gallons) main tank, it’s bigger than some of the ones the list. I’m also not sure if the 7 million liters of the L’Oceanogràfic in Valencia can be considered a single tank?

  6. Barbaros says

    List needs to be updated again as Turkey opened the biggest aquarium in the world yesterday in Florya (Istanbul).

  7. Adrian Tolliday says

    Well there are so many tanks missed from this list. How about the Atlantis Ambassador Tank in Dubai, which has 3m gallons seawater – i know cause I was the first in it when we filled it!

  8. Patrick says

    What about the one in Atlantis the palm? ambassador lagoon? its advertised to have 11.5 million litres and it looks like it could be to, I have also been to Dubai mall and Atlantis is definitely bigger. I agree with Aidrian Tolliday.

  9. Danielle Wilson says

    Shedd Aquarium in Chicago should have been # 2 with 5mil gallons….It was #1 until the Atlanta one came along

  10. elaine johnson says

    these places are a disgrace. marine creatures belong in the sea, not to be gawped at . so sad

  11. Nate Berkes says

    @elaine johnson
    Aqauriums are used for EDUCATIONAL PURPOSES. There 1st goalis to make money the 2nd EDUCATIONAL PURPOSES!!!!

  12. thegidget says

    @elaine johnson and @Nate Berkes
    Many Aquariums are non profit and barely meet the gigantic financial needs to care and house the animals. At our local aquarium many of the animals are rescues, deemed “non-releasable” meaning they were rehabilited from injuries but deemed not to be able to survive in the wild. These animals are ambassadors of their species, and usually treated and fed very well. Of course animals are usually happier in the wild, but in their case they would be dead without the aquarium’s care. Of course not all aquariums are run in such an ethical manner, so it is important to find out before giving them your financial support.

  13. Koen says

    The Burgers’ Ocean is an aqaurium in Arnhem, the Netherlands that holds >8 milion litres, wich is 2113376.42 Gallons if im not mistaken and should be included.

  14. Sharkbait says

    Singapore’s S.E.A. Aquarium on the island resort of Sentosa is the largest in the world. I read that it holds almost 12 million gallons and 100,000 animals

  15. M.L. says

    I’ve been to a few of these and will say that the Georgia Aquarium is great, though it was greater before they foolishly got rid of their 3 beautiful, big hammerheads. The Monterey Bay Aquarium is located in a real nice area and is well landscaped on a beautiful beach, but the exhibits are underwhelming. Event their main attraction, the big shark tank, is kinda lame. Their claim to fame is that they have on occasion had a juvenile great white on display. No telling when they will do that again but when they have great white it is obviously a very special place. Unfortunately, they rarely do.

  16. dan says

    Shedd Aquarium in Chicago has 5 million gallons in the oceonarium alone. It is much bigger than all of these with the exception of Georgia. (Georgia was modeled after Shedd.)

  17. Paul says

    I was involved in the manufacturing and installation of the acrylic windows for most of the above including the aquariums listed in some comments, the list has missed a few major aquariums but if based on water capacity per exhibit its probably correct, the large windows are laminated acrylic glass, the larger windows were lowered into the tanks in separate pieces , we would then bond each section ( anything from 2 – 20ton per section ) together inside the tank. Once completed the joints are smoothed and polished and the entire bonded window its pushed into place and sealed. The secret was to keep the joint ( also a clear acrylic ) to a minimum, usually between 3-5mm and the finished product looks to be almost seamless.

  18. Kris says

    I believe the Georgia Aquarium put the hammerheads back in the wild due to the fact that they had attacked one of the other animals and killed it.

  19. rick says

    Atlantis is a marine habitat that constantly communicates with the atlantic ocean but with filtering blockades to prevent escape. Not a TRUE AQUARIUM BY DEFINITION…

  20. Beth says

    Just visited Georgia Aquarium and I have to say I was not that impressed. I’ve visited a number of aquariums in the U.S. and would probably rate this one the lowest. Admission is now $37 and my family is still scratching our heads and wondering how it is rated as the largest aquarium in the world – it just did not seem that big. We used to go to Mystic aquarium in Connecticutt and we loved that but I thought Atlanta paled in comparisob.

  21. says

    About the Marine Life Park in Singapore: For this list we compared the size of the biggest tanks. The Open Ocean tank of the Marine Life Park is 4,800,000 gallon. So it is not the largest on this list.

  22. says

    @Max, 1 sizes are listed here in gallons not in liters. 2 for this list we compared the volume of the biggest tank of an aquarium, not of the entire aquarium The volume of the largest tank at Ripley’s Aquarium is 750,000 gallons. That’s not enough to make it to the top 10.

  23. Asad says

    @touropia thanks for sharing information about aquariums. I want to know how big is Ocean Kingdom’s tank?

  24. jimi says

    A few people have mentioned Disney’s Epcot. With 5.7 million gallons, that makes it second for saltwater tanks.

  25. Levi says

    Disappointed not to find my own workplace on this list. The Atlantic Sea Park in Norway has a tank housing Harbour Seals and various flounders with about 4 million US gallons of salt water. We also have The Atlantic Ocean Tank where we keep specimens of all the big coldwater fish of the Northern Atlantic Ocean, with just over 1.1 million US gallons of unfiltered sea water.
