It contains 1,500 exotic fish. The largest aquarium in the world crashes in Berlin

A huge Berlin aquarium housing some 1,500 oddly shaped fish collapsed on Friday, spilling a million liters of water and littering a huge road in the busy Mitte district, German emergency services said.

About 100 emergency services personnel rushed to the site, a luxury complex that is home to the Radisson Hotel, museum, shops and restaurants as well as what the Dome Aquarium says is the world's largest free-standing cylindrical aquarium at 14 metres.

For its part, Berlin police said on Twitter that "in addition to the unbelievable marine damage... two were hit by shards of glass."

"Emergency personnel could not enter the ground floor of the building because of the debris," a spokesman for the Berlin Fire Service said, adding that search and rescue dogs had been dispatched to the scene.

The spokesman said the cause of the fish tank explosion is not clear, while neither the fire service nor the police have commented on the fate of the fish.
