There's something fishy about this hotel prank A man has entered the Radisson Blu hotel in UK and climbed into the tank for a swim. A man has jumped into a hotel's fish tank. FOOTAGE showing a man climbing into a giant hotel lobby fish tank and going for a swim is making a splash on YouTube. The joker, called Matt, jumped fully-clothed into the tank at the Radisson Hotel in Jersey, US. His giggling friends filmed the stunt and encouraged him to swim around. They can be heard saying: "swim, go down there, down there" in between fits of laughter, as Matt lifts his body up and smiles through the glass. However it wasn't long before a furious hotel staff member approached and told him: "What are you f***ing doing? What are you doing that for, get out. The man eventually obliged, climbing out of the tank dripping wet before running away. We feel sorry for the fish. Follow our Travel Editor and Travel Reporter on Twitter.
