More than 100 first responders and rescue dogs reportedly swarmed the area, and amazingly there were no fatalities. A few people got minor cuts from pieces of glass, and 350 hotel guests were evacuated.
As for what caused the disaster -- that's still under investigation. Officials don't see a clear cause yet. As one hotel guest put it, "The whole aquarium burst and what’s left is total devastation. Lots of dead fish, debris."
