People Editorial Guidelines Published on December 16, 2022 08:32AM EST A massive aquarium inside the lobby of the Radisson Blu hotel burst on Friday, forcing thousands of gallons of water, tropical fish and debris into the frigid streets of Berlin, Germany. When the 50-foot-tall, 38-foot-wide AquaDom aquarium, described by its makers as the world's largest freestanding aquarium, exploded before 6 a.m. local time, it roused hotel guests from their sleep and later forced their evacuation, according to multiple outlets including The New York Times.

About 300 guests were evacuated from the hotel, according to the Associated Press. Adam Berry/Getty Images "It's a picture of devastation with lots of dead fish and broken shards," Sandra Weeser, a member of the federal parliament who was staying at the hotel, said in an interview with a local TV station, adding about the fish: "The ones that might have been saved were frozen to death." About 1,500 tropical fish spanning 100 species were enclosed in the cylindrical aquarium, which wrapped around the hotel's glass elevator and afforded an inside-out view of the sea life, per the Times.

"Our Plan A is to reactivate the electricity. Plan B would be to bring them to a safe location, and we have some offers from places that say they are ready to take them." Officials do not yet know the reason for the incident, but they were investigating any structural issues that may have affected the hotel as a result of the explosion.
