Fish Coloring Pages

Make free printable fish coloring pages from 13 fish pictures we drew ourselves: a clownfish in a sea anemone, an angelfish with long fins, a goldfish in a bowl, a pufferfish puffed up with its spines out, a betta fish with flowing fins, a butterflyfish by the coral, a koi in a lily pond seen from above, a trout jumping from a stream, a swordfish, a lionfish with spiny fins, a school of little fish, a catfish with whiskers and a big simple fish for little ones. Every fish is our own drawing of a real kind of fish, with one small eye and no smiles or cartoon eyes, and no film, book, game, toy or cartoon fish or characters, so the pages suit homes, classrooms and libraries. Print one big fish on a page, a grid of four or six small ones, a coral reef scene with an anemone, rocks and rising bubbles, a fold-in-half card, or a fish mandala with small fish round the edge and a new pattern at the press of a button. Blank fish to decorate prints 1, 2, 4 or 6 plain fish outlines with no eye, stripes or fin lines, so children can invent their own patterns; one fills a 186 mm square on US Letter. Type a child’s name for a name page, or paste a class list to get the same fish for everyone with each name at the top. Choose simple, medium or detailed lines, never thinner than 0.5 mm. Download one multi-page PDF for US Letter or A4, a 300 DPI PNG of every page, or an SVG. No sign-up, no watermark.

Blank fish to decorate

Fish per page	Each fits (US Letter)	Each fits (A4)
1	186 mm square	181 mm square
2	120 mm square	129 mm square
4	89 mm square	86 mm square
6	77 mm square	83 mm square

Sizes are for the page with No title chosen; a title at the top makes them a little smaller. Each blank outline is a plain fish (body, forked tail, dorsal fin, belly fin and side fin) with no eye, gill, stripes or fin lines (5 shapes), so the design is up to you.

Simple to detailed lines

Fish facts to read while you color

• Fish breathe oxygen, not air: fine blood vessels in their gills take the oxygen from the water.
• Most fish swim by tightening bands of muscle on one side of the body and then the other, which sweeps the tail from side to side.
• A fish scale grows rings, wider apart in summer and closer together in winter, so the rings can show a fish’s age.
• Clownfish make their homes among the stinging tentacles of sea anemones, protected by a coat of slime.
• Count the fins on the trout: a fish uses its tail to push and its other fins to steer and stay steady.

Coloring ideas

• Clownfish: orange with pale bands edged in black.
• Goldfish and koi: orange, gold, white and black patches, every fish different.
• Blank fish: invent your own stripes, spots and fin colors.

Printing tips

• Every page keeps a 12.7 mm (half inch) margin from the paper edge, on US Letter and A4.
• Plain paper is fine for crayons and pencils; use thicker paper or card for markers or paint.
• Print one page first and check it before printing a whole pack or class set.
• Choose Detailed lines only with fine pens or sharp pencils, and Simple lines with chunky crayons.

Frequently asked questions

Are these fish coloring pages free?

Are there cartoon fish from films?

No. There are no film, book, game, toy or cartoon fish or characters. The clownfish is drawn as the real fish, with its three pale bands and a small eye, in its sea anemone. Children can color it any way they like.

How are these different from the ocean, shark and jellyfish coloring pages and the fish template?

They are new drawings, all of fish. None repeats a picture from our ocean, shark, jellyfish, sea star, seahorse, whale or octopus pages, and the fish template prints plain outlines to cut out, not pictures to color. No outline is copied from those pages.

How do fish breathe?

Through their gills. NOAA Fisheries explains that fish breathe oxygen, not air: fine blood vessels in the gills take up the oxygen in the water.

Can children design their own fish?

Yes. Choose Blank fish to decorate and pick 1, 2, 4 or 6 per page. Each is a plain fish (body, tail, dorsal fin, belly fin and side fin) with no eye, stripes or fin lines. With no title, one fills a 186 mm square on US Letter; six fill 77 mm squares.

Which fish pages suit toddlers and preschoolers?

Choose Simple lines: big shapes with thick outlines. The big simple fish and the swordfish have the fewest shapes, as the table shows.

Can I make a page for every child in my class?

Yes. Choose Class set, pick a picture and paste the names, one per line, up to 40. Each child gets the same picture with their own name in hollow letters at the top, all in one PDF.

Are there fish coloring pages for adults?

Yes. Choose Fish mandala with Detailed lines: each pattern number gives a different symmetric design. Choose 16 repeats for the most intricate pattern.

Can I sell what I make with these pages?

Yes. The pictures are our own drawings, and the note under the tool sets out how you may use them, including for things you sell.

How do I print the coloring pages?

Download the PDF and print it on plain paper. Choose 100% or Actual size to keep the margins and sizes as drawn; Fit to page also works if your printer cuts off the edges.

Is anything uploaded?
