A single dark red betta fish swims near the surface of a fish tank. Its reflection is clearly visible on the water's surface, mirroring its movements. The fish has large, flowing fins that are a deep, rich red color. The tank's background or bottom appears to be a light-colored, textured surface, possibly sand or small pebbles. The water in the tank is clear. The fish moves slowly and gracefully, occasionally fanning its fins. There are no other visible subjects or objects in the frame besides the fish and its immediate environment within the tank.
