Rainbow Trout Pattern Illustration

A dense, full-frame pattern illustration of many rainbow trout arranged in rows, filling the entire canvas edge to edge with no empty background space and no cropped fish at the borders. Each fish is drawn in a detailed sketch style with fine lines showing scales, fins, and gills. Give each fish distinct, individual coloring — some with olive-green backs and bold pink-red lateral stripes, some more silvery-grey with muted pink tones, some with darker brown-olive backs and heavier dark speckling, some warmer golden-yellow tones — so no two fish look identical. Fine ink linework defines the anatomical details over the natural color palette. The fish are arranged in tight, evenly spaced rows against a plain tan/cream textured background. Every row alternates direction top to bottom — one row swimming left to right, the next right to left — packed closely with consistent spacing and no fish cut off at the edges. Traditional naturalist illustration style, vintage hand-drawn quality, attention to detail in snouts, eyes, and scales.
