The video shows a large aquarium filled with goldfish of various colors, including orange, black, and white. The fish are swimming around the tank, some near the surface while others are deeper down. The aquarium is well-lit, and the water is clear, allowing for a good view of the fish. The fish are of different sizes and shapes, with some having long fins and others being more rounded. The background of the aquarium is not visible, but the focus is on the fish and their movements.
