🎨 How to color it

Color the butterflyfish lemon yellow with charcoal-black bands, give the branching corals tangerine and lavender tones, and make the anemones soft seafoam green. Use sharp colored pencils for the fish’s narrow stripes, fin rays, coral dots, and tiny background fish, then switch to light side-strokes for the open water lines. Try a pale turquoise wash behind the bubbles so the bold black eye spot on the tail fin stands out.

The story behind this coloring page

The Eye That Guarded Sleep — Before moonrise, Marlo tucked crumbs of sponge into the smallest coral cracks, where the night-singers lived. Read the full story →

Before moonrise, Marlo tucked crumbs of sponge into the smallest coral cracks, where the night-singers lived. They were tiny fish with glassy fins, and they only ate after the reef grew quiet. Marlo wanted every crack to have supper before the silver current arrived, but the reef wrasse kept snapping up anything left in the open. The water smelled of salt and crushed shells as Marlo searched for one last place to hide a meal.

He poked his long snout under a folded shell, inside a tube sponge, even between the soft arms of an anemone. Nothing stayed safe. Then a bubble popped against his tail—pip!—and Marlo felt a hollow notch behind his back fin, a place nobody thought to look because it seemed like plain shadow. He packed the crumbs there and whispered, “For after dark.”

When the wrasse swooped by, it froze at the dark round mark beside Marlo’s tail, mistaking it for a wide-open eye. The crumbs stayed hidden until the night-singers came out, nibbling in little silver sparks. Ever since, butterflyfish have carried that watchful tail-eye, guarding secret suppers nobody saw them give; next time you spot Marlo among the coral, see if that quiet eye is still keeping moonrise watch.
