Weighing in at 40 tons and ~40,000 liters, or 13,000 gallons, Kamo Aquarium has built what is likely the largest jellyfish tank in the world. Kamo Aquarium recently opened their new building featuring the largest jellyfish collection in the world with 30-40 species always on display. They also hold the Guinness World Record for most jellyfish species displayed.
Other aquariums have recently claimed the title of ‘largest kreisel tank’ such as Ripley’s Aquarium of Canada in Toronto (16,500 liters) and Georgia Aquarium’s 25,000 liter tank but Kamo Aquarium stepped in and almost doubled the volume with their new flagship tank! The tank holds approximately 10,000 moon jellies! The window/viewing area is a whopping 5 meters by 5 meters, very impressive. The tank itself is much bigger, about 2 meters wide:
The renovated Kamo Aquarium opened June 1st to the public so go visit! Or follow their progress at their Facebook page.
