Cá vàng dưới nước

A hyper-realistic, ultra-detailed close-up of a vibrant orange goldfish swimming underwater, cinematic composition. The goldfish has large flowing fins and a rounded body with highly detailed, glossy, reflective scales shimmering in shades of bright orange, gold, and subtle white gradients. The fish's eyes are large, expressive, and glossy with realistic reflections.

Surrounding the main goldfish are multiple smaller goldfish in the background, softly blurred with depth of field (bokeh effect), creating a sense of depth and motion. The underwater environment is filled with floating air bubbles of varying sizes, sharply detailed in the foreground and gradually fading into soft focus in the background.

Lighting is soft, diffused underwater light rays coming from above, creating a magical glow and illuminating the fish’s scales with high contrast and reflections. The background is a gradient of deep blue to turquoise water tones, slightly blurred for emphasis on the subject.

Highly realistic water refraction, caustics, and light scattering effects. Ultra HD, 8K resolution, sharp focus on main subject, shallow depth of field, macro photography style, vibrant colors, photorealistic rendering, cinematic lighting, professional underwater photography.
