A medium shot from a slightly high-angle perspective looking down into a crystal-clear, turquoise ocean. A vibrant school of small, beautifully colored tropical fish, shimmering in iridescent shades of neon yellow, electric blue, and vivid orange, swim in a swirling formation through the water. Below them, a pristine white sandy seabed is scattered with intricate coral reefs in deep purples and bright pinks, with gentle ripples of light dancing across the ocean floor. The atmosphere is serene and ethereal, characterized by brilliant, luminous lighting filtering through the water's surface in sharp rays of sunlight. The color palette is a vivid array of oceanic blues and corals, featuring high-clarity water effects, tiny suspended bubbles, and a sense of weightless tranquility in a high-quality anime illustration style.
