Aquarium Fish Coloring Pages (Free PDF Printables)

Home›Free Printable Coloring Pages

By: Papaya Ink Team · Last updated: October 19, 2026

A home aquarium is a slice of river brought indoors, and the fish that live in one are among the most carefully bred and closely watched animals on the planet. These aquarium fish coloring pages are drawn from real species, the ones people actually keep: schooling tetras, livebearers such as guppies, mollies and platies, tall cichlids, long-finned bettas and fancy goldfish. Each fish swims among plants, driftwood or gravel with its common name lettered underneath, so the sheet works as a coloring page and a small field guide to the tank at the same time.

Click any picture and the full-size PDF opens in a new tab, ready to print. The sheets are sized for US Letter paper and print just as cleanly on A4. The line art is crisp black on pure white, so even a basic home printer gives sharp edges for colored pencils, markers or watercolor.

Aquarium fish are a fun coloring challenge because much of their color is made of light rather than pigment. On a shimmering stripe, lay down turquoise first, deepen the edges with darker blue and leave a thin line of bare paper through the middle. Silver bodies look best in cool grays with an untouched highlight along the back. Fins are nearly transparent, so color them with a light hand and let the ray lines stay visible. A photo of the real species propped next to the sheet is the best color guide there is.

Fun Things to Make with These Coloring Pages

  1. Shoebox aquarium – paint the inside of a shoebox blue, glue sand and pebbles along the bottom, then cut out the colored fish and hang them from the lid on clear thread so they drift at different depths.
  2. Cereal box tank – cut a window in the front of a cereal box, cover it with clear plastic wrap and tape the fish inside with strips of green paper for plants. Tap the box and the fish wobble.
  3. Fin-glow suncatchers – color with markers, brush a thin coat of baby oil over the back of the paper and let it soak in on paper towels. Cut the fish out and tape them to a sunny window; the fins glow like the real thing.
  4. Tank ID cards – for a home or classroom aquarium, color the species that actually live in it, trim them to card size and tape them near the glass so visitors can match every fish to its name.
  5. Magnet fishing game – cut out the fish, slide a paper clip onto each nose and catch them with a magnet tied to a string on a stick. Write a point value on the back for older players.
  6. Hanging mobile – glue each colored fish back to back with a second copy, punch a hole near the dorsal fin and hang the pairs at different heights from an embroidery hoop or a bare branch.
  7. Slim fish bookmarks – cut a long strip around one of the slender tetras, cover it front and back with clear packing tape and punch a hole at the tail for a ribbon.
  8. Memory versus photo – color the same fish twice, once from memory and once from a picture of the real species, and put them side by side. It is a quick lesson in how much detail the eye skips.
