A glass aquarium, located in Kawungluwuk, Indonesia, contains a dense cluster of at least eight Oscar fish (Astronotus ocellatus). The fish exhibit dark bodies with prominent orange and black marbled patterns. The water level is visible, with numerous small air bubbles present on the surface. A white and silver floating thermometer is positioned near the water's surface, reflecting ambient light. The scene is illuminated by an intense light source, likely overhead or from behind the camera's perspective, causing significant glare on the upper portion of the aquarium glass and reflections of an indistinct background. No human subjects are visible within the frame. The immediate environment appears to be an indoor or sheltered setting, given the presence of the aquarium setup.
