<div style="background:#0E2530;color:#CFE0DE;padding:14px 16px;font-family:monospace;font-size:13px;white-space:pre-wrap;border-radius:4px">Photorealistic top-down photograph looking straight down into an open-top low rectangular aquarium, 60 x 30 cm as seen from above, water surface filling the frame. Pale inert light-tan sand visible through clear water, with a gentle diagonal gradient from thinner sand at front-left to slightly deeper at rear-right — NO dark active substrate. A cluster of grey stones and two driftwood branches cross diagonally from lower-left to upper-right, both draped in dark green java moss. A round marimo moss ball sits alone on open sand in the lower-right area. Cryptocoryne plants form a dense green band along the top edge of the frame only. Floating salvinia with trailing roots covers roughly the left half of the surface, casting dappled shadow on the sand beneath; the right half of the surface is completely open water with clear visibility to the bottom. A pale green cylindrical sponge filter is visible in the upper-right, a thin stream of small bubbles breaking the surface beside it. Roughly twelve deep cobalt-blue dwarf shrimp are visible on the sand and moss, seen from above, some mid-graze. The lower-right third of the frame is bare open sand with nothing in it, clearly readable as empty. Soft even overhead lighting, gentle water-surface reflections, natural colour, no artificial saturation. Absolutely NO carpeting foreground plants, NO CO2 Ver más
