The image displays a male Betta splendens (Siamese fighting fish) inside an aquarium. The fish exhibits a dark blue body that transitions into vibrant blue and teal fins, with reddish-orange coloration evident on its ventral and anal fins. Its large caudal fin is flared in a distinct fan shape. The fish is positioned in the water column, oriented towards the left. The aquarium environment includes a substrate composed of small, irregular white and light beige pebbles. A cluster of thin, bright green aquatic grass-like plants occupies the foreground. To the right, a broader-leafed green aquatic plant is situated within a textured, greyish-brown pot or rock structure. Visible aquarium equipment includes a spherical clear object, likely an air stone or aerator, near the water surface, and black cylindrical components, possibly part of a filter or heater, visible behind the right-side plant and as reflections. The background, visible through the tank and as reflections on the water and glass, consists of blurred indoor elements, including a prominent orange-red object situated behind the fish. The water inside the tank is clear. The specified location in the city of Bistritsa, Bulgaria, cannot be independently verified from the visual content of the image.
