The video shows a close-up of an aquarium with a blue background. There are several fish swimming around, including a yellow and orange fish and a red fish. The yellow and orange fish has a long, thin tail and a white underbelly, while the red fish has a shorter tail and a more vibrant color. The aquarium is filled with multicolored gravel, and there is a black tube-like object in the background. The fish are seen swimming in different directions, sometimes coming close to the camera and other times swimming away.
