The image is a close-up of a piranha fish swimming in an aquarium. The fish is facing towards the right side of the image, with its head slightly tilted upwards. Its body is a dark grey color with a hint of orange on its belly. Its eyes are large and round, and its mouth is slightly open, as if it is looking directly at the camera. In the background, there are other piranhas swimming in the same direction. The water is clear and there are small rocks and algae visible.
