The fish, which appear to be of the same species, have a distinctive shape with a large head and a small mouth. They move gracefully through the water, their fins and tails gently propelling them forward. The background is a clear, vibrant blue, indicating the depth and clarity of the ocean. Small particles or plankton can be seen floating around, adding to the natural ambiance of the underwater environment. The overall mood of the video is calm and peaceful, showcasing the beauty of marine life.
