In the video, a person is seen holding a fish in an aquarium. The fish is dark in color and has a large mouth. The person then releases the fish, and it swims away. In the background, there is another fish that is red and black in color. The aquarium appears to be well-lit, and the water is clear. The person's hand is visible as they hold the fish, and they seem to be wearing a ring on their finger. The fish swims away gracefully after being released.
