The image shows an aquarium with a large tank filled with water and various types of fish. The tank is located in a dimly lit room with a wooden floor and a railing on the right side. The water is a deep blue color and there are several small fish swimming around the tank. On the left side of the tank, there are rocks and plants visible. In the background, there is a large rock formation and a few smaller fish swimming in the water. The image appears to be taken from a low angle, looking up at the tank and the fish.
