A hyper-detailed fantasy underwater scene featuring a glowing blue koi fish swimming gracefully in clear, deep ocean water. The fish has large, expressive glossy eyes, smooth rounded facial features, and delicate whiskers. Its body is covered in highly detailed shimmering scales in shades of sapphire blue, turquoise, and hints of gold, reflecting light like gemstones. The fins are large, translucent, and flowing like silk, glowing softly with iridescent highlights, with a magical aura.

Surrounding the fish are floating crystal-like stones, glowing particles, and tiny golden light orbs scattered throughout the scene, creating a dreamy, magical atmosphere.
