Here's a description of the video: The video shows a large aquarium with a man dressed as a merman swimming inside. He has a bare torso and wears a blue tail. He swims horizontally across the tank, surrounded by various fish. A crowd of people stands in front of the aquarium, watching the performance. Many are holding up their phones to record the merman. The room is dimly lit, and the top of the aquarium's decorative border is visible.
