In the video, we see a close-up of a fish tank with several discus fish swimming around. The fish are mostly white with some red and yellow markings. The person filming is seen reaching into the tank and touching one of the fish, causing it to swim away. The fish are of different sizes and are swimming in different directions. The water in the tank is clear, and we can see the bottom of the tank. The lighting in the room is bright, and the fish are clearly visible.
