In the video, we see a person's hand reaching into an aquarium. The aquarium is filled with water and various types of coral. There are two fish swimming around in the water, and the person's hand is seen petting one of the fish. The fish are orange and white in color, and they swim around the coral and rocks in the aquarium. The person's hand is visible in the foreground, and the fish are in the background. The aquarium is well-lit, and the water is clear, allowing us to see the details of the fish and the coral.
