The video shows two arapaima fish in a freshwater tank, likely at an aquarium. The arapaima are large, greyish-silver fish with scale patterns visible. They have a long, cylindrical body shape and broad, flattened heads. One fish is positioned slightly behind the other, closer to the camera. Both fish are relatively still, possibly resting near some driftwood on the tank floor which consists of small rocks. The water is clear. There are sounds of people talking, including children, in the background.
