The video shows a large aquarium with a variety of fish swimming around. There are several types of fish visible, including a large shark and a smaller fish with yellow and black stripes. The aquarium is well-lit, and the water is clear, allowing for a good view of the fish. The fish are swimming around the tank, some near the surface and others deeper down. The shark is swimming slowly, while the smaller fish with yellow and black stripes is darting around quickly. The aquarium appears to be in a public space, possibly a museum or aquarium, as there are people visible in the foreground observing the fish.
