The video shows a white fish with red fins swimming in a dark aquarium. The fish is seen swimming around a piece of driftwood and occasionally coming up to the surface of the water. The fish appears to be healthy and active, with its fins and tail moving smoothly as it swims. The aquarium is dimly lit, with the only source of light coming from above, casting a spotlight on the fish. There are no other fish or objects visible in the aquarium, and the background is dark and indistinct.
