A single fish, appearing to be a *Channa* species, approximately 15-20 cm in length, is observed swimming horizontally, facing right, within a glass aquarium. The fish exhibits a mottled dark brown and tan patterned coloration along its body. The aquarium contains clear, greenish-tinted water with a dark, granular substrate at the bottom. An artificial background depicting an underwater scene in various shades of green and teal is visible behind the fish. A bright, circular light reflection dominates the left side of the aquarium glass, partially obscuring the view and reflecting a grid-like structure and several small, elongated reddish objects. A light-colored frame borders the right edge of the aquarium. The scene is located in Ciherang, Indonesia. No human subjects or direct interactions are visible.
