It has a grayish-brown coloration with darker spots on its body and fins. Its mouth is open, as if it is about to take a bite out of something. The water is a deep blue-green color and there are a few small fish visible in the background. The aquarium is made of clear glass, allowing the viewer to see the fish inside.
