The image shows a small fish swimming in an aquarium. The fish is grey in color and has a long, slender body with a pointed snout. It is swimming towards the right side of the image, where there is a small white fish lying on the sand. The sand is dark and there are a few small rocks and debris scattered around the fish. In the background, there are two other fish, one yellow and one green, swimming near the surface of the water. The image appears to be taken from a low angle, looking up at the fish and the sand below.
