The video shows a close-up of an aquarium with several fish swimming around. The fish are of different sizes and colors, including white, yellow, and black. They are swimming in and out of the frame, around a large piece of driftwood that is in the center of the tank. The driftwood has a rough texture and is covered in algae. The aquarium is filled with clear water, and there are small rocks and pebbles on the bottom. The fish are moving quickly, and their fins and tails are visible as they swim.
