The video shows a group of fish swimming in an aquarium. The fish are white and appear to be of the same species. They are swimming around in the water, occasionally coming close to the camera. The aquarium is well-lit, and the water is clear, allowing for a good view of the fish. There are no visible plants or decorations in the aquarium, and the background is dark, which makes the white fish stand out. The fish are moving smoothly and seem to be healthy and active.
