In the video, a man is seen standing in a room with a blue bucket. He is wearing a black shirt and a cap. The man is using a long metal hook to clean the inside of a glass tank. He dips the hook into the bucket and then uses it to scrape the inside of the tank. The man is focused on his task and appears to be thorough in his cleaning. The room has a green wall and a white door in the background. The blue bucket is placed on the floor next to the man. The man's movements are deliberate and careful as he cleans the tank.
