In the video, a man is seen walking down a row of fish tanks. He is wearing a blue shirt and glasses and appears to be observing the fish in the tanks. The tanks are lined up in a row and are filled with water and fish. The man seems to be inspecting the fish and the tanks as he walks past them. The lighting in the room is dim, and the tanks are illuminated from above. The man continues to walk down the row of tanks, stopping occasionally to look at the fish more closely.
