How to Make an A for Aquarium Craft
Step 1: Draw and Cut Out the Fish Tails
Begin by making the fish tails.
Take a piece of colored paper and use a black marker to draw a simple triangle. It doesn’t need to be perfectly shaped since it will become the tail of the fish.

Carefully cut out the triangle with scissors. Repeat this step using different paper colors if you want several colorful fish in your aquarium.
Tip: Keep the triangles roughly the same size so the fish look balanced.
Step 2: Fold the Paper to Create the Fish Body
Now create the fish body using an accordion fold.

Cut a rectangle from colored paper. Starting at one short edge, fold a narrow strip forward. Flip the paper over and fold it back in the opposite direction. Continue alternating folds until you reach the other end of the paper.

Press each fold firmly to create neat creases. When finished, the paper should resemble a small fan. This folded piece becomes the body of the fish and gives the craft its three-dimensional appearance.
Repeat this step with different paper colors to make multiple fish.
Tips
- Keep the folds evenly sized.
- Press firmly on each crease.
- Younger children may need help with folding.
Step 3: Make the Aquarium
Next, create the aquarium background.
Draw a large circle on a sheet of white paper and carefully cut it out. The circle will represent the aquarium or fishbowl.

Use a blue marker to color around the edge of the circle to create the glass border. Then glue the circle onto a larger sheet of green paper, which becomes the background.
Leave plenty of space inside the circle for your fish and some room along the bottom for underwater plants.
Step 4: Assemble the Fish
Now it’s time to put the fish together.
Take one accordion-folded paper body and glue one paper triangle to the back to create the tail.
Next, add a small paper eye near the pointed end of the folded paper. You can use googly eyes or make simple eyes from white and black paper circles.
Repeat until you’ve made several colorful fish.

Before gluing them onto the aquarium, arrange the fish inside the circle to decide where each one should go. Point some fish in different directions to make the aquarium look more natural.
Once you’re happy with the layout, glue each fish in place.
Tips
- Use only a small amount of glue.
- Leave space between the fish.
- Mix different colors to create a lively aquarium.
Step 5: Add Seaweed and Finish the Aquarium
To complete the underwater scene, cut several long, wavy strips from green paper. These become the seaweed growing along the bottom of the aquarium.
Arrange the strips in different heights before gluing them down. Keeping the seaweed uneven creates a more natural look.

If you’d like, lightly draw underwater grass or bubbles using colored pencils or crayons for extra detail.
Once everything is glued securely, allow the craft to dry completely before displaying it.
Congratulations! Your A for Aquarium Craft is finished.
