A fierce-looking tropical fish drawn in pen-and-ink style: a deep, disc-shaped body, spiny dorsal and anal fins that trail away into fine points, and a distinctly unimpressed mouth. Every scale and fin ray is hatched by hand, so this is a page for people who enjoy slow, detailed work. The PDF is free, needs no registration, and prints at home.

Have you ever kept fish at home? What did you keep them in?
Do you remember visiting an aquarium, and which tank you stood in front of longest?
Which do you find more beautiful — the fish of rivers, or the bright fish of warm seas?
If you could give this fish any colors at all, which would you choose?
What kind of fish is this?
It is not a portrait of one documented species. The artist has gathered features found across warm-water reef and aquarium fish — a tall, flattened body, spines running along the back, long streaming fin tips — into a single scowling fish. That freedom is useful when you sit down to color it: nothing on this page has a correct color, so it can go anywhere from a natural blue and silver to something invented outright.
How do you color over all that hatching?
The drawing is built from fine ink strokes rather than flat outlines, so heavy color will bury it. Colored pencil works best: keep the pressure light and build two or three thin layers, letting the ink show through as the shading. Leave the most densely hatched areas — the shadowed belly, the gill cover — almost untouched and they will read as depth on their own. Markers and watercolor both flood the strokes, so save those for a plain background if you want one.
Why are tropical fish so brightly colored?
The usual explanations are that strong patterns help fish recognise their own kind on a crowded reef, warn rivals off a patch of territory, or break up the body outline against coral and shifting light. Which of these matters most differs from species to species, and researchers still argue over particular cases. The practical point for coloring is that almost any bold combination you choose has a real counterpart somewhere in a warm sea.
