In the video, a man is seen walking through a large room filled with rows of fish tanks. The man is wearing a black shirt and has short hair. He is walking slowly and looking at the fish tanks as he passes by them. The fish tanks are filled with water and have several fish swimming in them. The room is well-lit and has a high ceiling with metal beams. The man continues to walk through the room, occasionally stopping to look at the fish tanks more closely.
