The image is a close-up of a small fish swimming in an aquarium. The fish appears to be a type of jellyfish, with a round body and a long, slender body. It has a light blue-green color with darker spots on its head and neck. The body of the fish is covered in small bumps and ridges, and its eyes are large and round. The background of the image is dark, with small white dots scattered throughout, creating a starry night sky. There is also a small yellow dot in the top right corner, which could be a star or a nebula. The image is taken from a low angle, looking up at the fish.
