In the video, a man is seen walking down an aisle of fish tanks. He stops at one of the tanks and begins to clean it. The man is wearing a black t-shirt and a baseball cap, and he is using a white cloth to wipe the glass of the tank. The fish tanks are lined up in rows, and each tank has a different type of fish swimming in it. The man seems to be taking his time and being careful not to disturb the fish too much. The lighting in the room is bright, and the tanks are well-maintained.
