A stunning, hyper-realistic, macro photography close-up of a single, vibrant Betta fish (*Betta splendens*) in a classic, thick-walled glass fishbowl. The fish is captured mid-swim, its flowing, iridescent fins—in hues of deep sapphire blue and fiery crimson—trailing gracefully through the crystal-clear water. Every individual scale reflects the soft, diffused light from a nearby window, showing microscopic texture and color variation. The glass of the bowl is slightly distorted, creating subtle, organic lens flares and a beautiful bokeh of a sunlit room interior blurred in the background. Droplets of condensation bead on the outside of the glass. Shot with a 100mm macro lens at f/2.8, capturing incredible detail and a shallow depth of field that makes the fish's eye—sharp, intelligent, and wet—the absolute focal point. Photorealistic, 8K resolution, studio lighting quality.
