The video shows a person's hand reaching into a tank of water and touching a fish. The fish is long and slender, with a smooth, shiny body that reflects the light. The person's hand is visible in the frame, and the fish swims around the tank, occasionally coming close to the glass. The water in the tank is clear, and the background is a solid blue color, which contrasts with the fish's silver color. There are no other objects or creatures visible in the tank.
