caption: The image shows a small fish swimming in the ocean near some rocks. It is a photo of mosquitofish, a species of fish native to the Mediterranean Sea. The fish is swimming gracefully through the water, its scales glistening in the light. Its fins are spread out, and its eyes are wide open, giving it a curious expression. The rocks in the background provide a stark contrast to the vibrant colors of the fish, making it stand out even more.
