 Step-by-Step Crochet Instructions

 Step 1: Crochet the Fish Body

1. Rnd 1: With your main color (e.g., blue), make a Magic Ring and work 6 sc inside. (6)

2. Rnd 2: Inc in each st. (12)

3. Rnd 3: (1 sc, inc) repeat 6 times. (18)

4. Rnd 4: (2 sc, inc) repeat 6 times. (24)

5. Rnd 5–8: 1 sc in each st around. (24)

6. Rnd 9: (2 sc, dec) repeat 6 times. (18)

7. Rnd 10: (1 sc, dec) repeat 6 times. (12)

8. Stuff the body firmly with fiberfill.

9. Rnd 11: Dec around to close. (6)

10. Fasten off and close the hole with a yarn needle.

Tip: Keep your stitches tight so the stuffing doesn’t peek through.

 Step 2: Crochet the Tail Fin

1. With a contrasting color (like yellow), ch 6.

2. Row 1: Starting from the 2nd ch from hook, work 1 sc, 1 hdc, 2 dc, 1 tr (treble crochet).

3. Turn and work on the opposite side of the chain: 1 tr, 2 dc, 1 hdc, 1 sc.

4. Slip stitch to join and fasten off.

5. Leave a long tail for sewing.

Sew the tail firmly to the back of the fish’s body. The tail should fan out slightly giving your fish that classic wavy look! 

 Step 3: Crochet the Side Fins (Make 2)

1. Using a different color (for contrast), ch 4.

2. Row 1: Work 1 sc, 1 hdc, 1 dc into the chain.

3. Turn and work 1 sl st back to the beginning.

4. Fasten off and leave a small tail for sewing.

Attach each fin to the sides of the fish’s body — one on each side, just behind where the eyes will go.

 Step 4: Crochet the Top Fin

1. With another bright color, ch 6.

2. Row 1: Starting in 2nd ch from hook, 1 sc, 1 hdc, 2 dc, 1 tr.

3. Turn, ch 1, and slip stitch along the edge to create a curved finish.

4. Fasten off.

Sew the fin to the top of the fish’s body, slightly off-center for a playful look.

 Step 5: Crochet the Bottom Fin (Optional)

If you want extra detail, you can add a small fin underneath.

1. Ch 4, work 1 sc, 1 hdc, 1 dc.

2. Fasten off and sew to the bottom of the fish.

This gives your amigurumi a full, 3D effect — perfect for display!

 Step 6: Add the Eyes and Embroidery

• Place safety eyes between rounds 5 and 6, leaving about 6 stitches between them.

• If you prefer embroidered eyes, use black thread and make small round stitches.

• You can also add a tiny smile or blush cheeks using a bit of pink yarn.

Pro Tip: Use pastel yarn for a cute, baby-fish vibe — or go bold with neon for tropical energy!

 Step 7: Final Assembly

1. Check the placement of all fins — adjust before sewing permanently.

2. Secure each fin with tight stitches so they stay in place.

3. Hide all yarn ends inside the fish’s body.

4. Shape it gently by pressing and rolling it in your hands.

Your adorable Colorful Little Fish Amigurumi is now complete! 

 Turning It Into a Keychain or Toy

Want to make it extra functional? Here’s how!

• For a Keychain: Attach a jump ring or small yarn loop on top of the head. Add a keyring or lobster clasp.

• For a Baby Mobile: Make 4–5 fish in different colors and hang them with transparent thread from a circular frame.

• For Kids’ Toys: Skip safety eyes and embroider them instead for safety.

 Pro Tips for Beginners

• Keep your stitches tight so stuffing doesn’t show.

• Use stitch markers to track rounds.

• Don’t overstuff — the fish should remain soft and slightly flexible.

• Try gradient yarn for a natural, oceanic look.

• Add glitter thread or shiny yarn for a “sparkling scale” effect.

 Creative Variations

• Rainbow Fish: Use leftover yarn scraps — change color every few rows.

• Pastel Baby Fish: Perfect for nurseries or baby gifts.

• Ocean Set: Make a whale, starfish, and seahorse to match your little fish.

• Keychain Bundle: Create a mini ocean family — perfect for Etsy or craft fairs.
