The Tranquil Depths

a small, colorful tropical fish resting peacefully among vibrant coral formations on a coral reef. The little fish has bright scales in shades of orange, yellow, and blue, with delicate fins gently swaying. It is nestled between branching coral structures in pink, purple, and turquoise hues. Soft rays of sunlight filter down through the crystal-clear water from above, creating dappled light patterns and a dreamy, ethereal glow. Small particles and bubbles float in the water. The reef is teeming with life - sea anemones, colorful coral polyps, and small sea plants. The background fades into a soft, deep blue ocean. Peaceful, tranquil atmosphere, vibrant colors, soft lighting, volumetric lighting.
