Use the uploaded seahorse family image as the exact locked identity, count, size hierarchy, side-facing orientation, formation, colour and material reference. Create one uninterrupted five-second reversible anatomical micro-motion on the existing pure black #000000 matte with a completely fixed camera. All three seahorses remain in exactly the same clear side profile and face the same direction as the uploaded image for every frame. Keep every complete snout, crown, belly, dorsal fin and curled tail fully visible inside the central 70 percent of frame with at least 15 percent empty space on every edge. The family remains centered with no travel. Animate only rapid restrained dorsal-fin flutter, tiny pectoral-fin corrections, subtle gill breathing and three slightly offset vertical bobs no larger than two percent of frame height. Keep the torso axis, side silhouette and curled-tail shape stable. The motion must remain smooth and physically plausible when played backward after the final frame. Preserve exactly three individuals and the exact bronze-cyan premium painted 2.5D texture. NEGATIVE PROMPT: No yaw, no turn toward camera, no edge-on body, no front view, no roll, no spin, no direction change, no head turn, no torso twist, no new background, seagrass, coral, particles, bubbles, camera movement, zoom, cut, full-group travel, static-card slide, fourth or missing seahorse, size or position swap, collision, merged or straightened tails, detached fins, horse legs, cartoon face, opacity fade, morphing, blur, crossfade, ghost family, freeze, text, logo, UI or reels.
