The aquarium is filled with various types of fish, including a large fish that swims up to the glass and faces the cat. The cat seems to be intrigued by the fish and continues to watch them. The aquarium is decorated with rocks and plants, creating a natural environment for the fish. The lighting in the room is dim, highlighting the glow of the aquarium lights.
