Ultra-realistic mounted micro-camera POV from a small reef fish weaving through narrow coral passages deep underwater, the camera physically strapped to the upper back facing forward with slight vibration from swimming motion, 5 to 10 percent of the fish visible at the bottom edge of frame, realistic reef density with swaying coral polyps, tiny shrimp movement, schools of fish crossing naturally, particles drifting through water, natural sunlight fading with depth, occasional body collisions causing subtle jolts, authentic marine research footage, no drone behavior, no floating camera, no cinematic color grading, no narration, no dialogue, only underwater current sounds, fin movement, reef crackling, and muffled water acoustics
