The image depicts an aquatic environment, specifically an aquarium, containing two fish and various submerged elements. **Location:** The specific city of Varna, Bulgaria, cannot be determined from the visual information present in the image. The scene is an interior view of an aquarium. **Scene Description:** The primary subjects are two fish. On the upper left, a small fish with a reddish-orange tail and ventral fins, and a darker dorsal region, faces generally right and slightly upwards. Its eyes are visible. On the middle-right, a black fish with a distinct, elongated, and deeply forked tail fin, which is dark red or maroon, faces left. This black fish has prominent white or light-colored eyes. The environment is characterized by water containing numerous small air bubbles, particularly near the top surface and scattered throughout the water column. The background behind the water appears to be a muted greenish-blue. Reflections of external light sources and indistinct shapes are visible on the glass of the aquarium. The bottom of the aquarium features a substrate composed of various rocks or pebbles, predominantly in shades of brown and grey. Green, moss-like aquatic plant matter is present on the substrate, particularly on the left side, intermingled with darker, stringy algae or plant growth. Aquarium equipment is visible on the right side, consisting of clear plastic tubing, likely part of a filtration or aeration system, running vertically. This tubing is secured by small clear clips or suction cups near the top. A thin white line, possibly another tube or cable, is also present near the vertical tubing. No human figures are present in the frame.
