Jellyfish city in an aquarium

Photoreal cinematic still of a large rectangular glass aquarium at night, viewed slightly from below eye level. Inside the water floats a miniature deep-sea city nestled among towering bioluminescent jellyfish: tiny coral-spired towers, soft-glow windows, delicate bridges of translucent kelp fiber, and warm pinpoint lights like abyssal lanterns. Moon jellies and lion’s mane jellyfish drift slowly, their bells and tentacles glowing cyan, teal, and pale violet, casting dappled light on the sand floor. Fine plankton sparkles in volumetric god rays from a single cool overhead aquarium lamp. Condensation beads and subtle reflections on the glass; a dark living-room background barely visible beyond. Ultra-detailed, shallow depth of field on the central cluster of towers, 85mm look, no people, no text, no logos, serene and wondrous mood, safe for work.
