### Full prompt
```text
A highly detailed vertical marine illustration of a crowded school of fish on a clean, solid white background. Edge-to-edge portrait composition in 2:3 aspect ratio with small white negative-space gaps between fish and no outer frame.

Subject & Composition:
Exactly 55 fish total: 5 large feature fish and 50 smaller baitfish. The 5 large fish comprise: 1 huge blue tuna-like fish across the top with a tall dorsal fin and large golden eye, partially cropped at the right edge; 1 long silver-and-blue barracuda-like predator across the middle-left with a pointed snout and visible teeth; 1 [pink, coral red, and warm gold] snapper-like fish on the right-center with golden eye and rosy fins; 1 large deep-blue tuna-like fish across the lower middle with a round black eye and pale belly; 1 long silver-blue barracuda-like predator along the lower section with sharp jaw and teeth. The 50 smaller fish are slim sardine or mackerel shapes swimming horizontally left-to-right and right-to-left, densely distributed around the larger fish.

Visual Style:
Intricate watercolor illustration combined with delicate pen-and-ink linework, bright reflective scales rendered as hundreds of tiny circular sequin-like dots, subtle metallic sparkle, crisp anatomical outlines, translucent fins, and layered blue shadows. Palette dominated by [cobalt blue, ultramarine, icy white, silver, and pale cyan], contrasted by the single warm accent fish.

Text:
In the bottom-right corner, a tiny printed date "[July 11, 2026]" and a delicate handwritten signature "[Oyagi]".

Constraints:
No humans, no background scenery, no water surface, no air bubbles, no frame border, no additional text. Keep every fish crisply defined against the white negative space.
