The video shows a large fish swimming in a blue aquarium. The fish has a white body with black spots and a long tail. It is swimming slowly and gracefully, with its fins moving gently. The aquarium is well-lit, and the water is clear, allowing for a good view of the fish and its surroundings. There are no other fish visible in the video, and the background is a plain blue color, which contrasts with the fish's white and black coloration.
