It is swimming near the bottom of the water, which is covered in some aquatic plants. The water is clear, and the fish is the only visible creature in the frame. The fish moves slowly and gracefully through the water, occasionally changing direction. The video is shot from above the water, giving a clear view of the fish and its surroundings.
