- Do not close! Begin working tail fin directly.

Tail Fin (No Sew)
- Flatten opening; you now have 3 paired stitches (one on each side).
- Work through both layers to seam and build tail:
- In first pair of stitches, work [hdc, hdc] (2 hdc in that "side")
- Next pair: hdc
- Next pair: [hdc, hdc] (2 hdc)
(You should have 5 stitches across.)
- Ch 1, turn.
- Row 1: hdc in first st, inc in next, hdc in next, inc in next, hdc in last st (7 hdc)
- Ch 1, turn.
- Row 2: hdc in each st across (7 hdc)
Fasten off, leaving long tail. Weave or hide ends neatly.
Dorsal Fin/Belly "Fringe"
- Begin at the top of the head (right above eyes/stripe), attach yarn as desired (yellow).
- Slip stitch or sc along the dorsal (top), then ch 4, turn, work dc in first next st, 2 dc in each of next 3 sts, hdc in next, sl st in next-end or modify number based on fish's back length and desired "fringe" height.
- Weave end inside and trim.

Face
- Place safety eyes between Rounds 4-5, or embroider as desired.
- Eyes should be spaced approximately 2-3 sts apart and centered between fins.
- Optional: Embroider a small mouth with black or pink yarn underneath eyes.
Assembly & Finishing
- Ensure all yarn tails are woven into the body.
- If making a keychain, securely attach a keyring through the top middle of the body (just behind the dorsal fin).
- Ensure all fins/tail details are adjusted for symmetry.
- Fluff stuffing and shape the fish gently using your hands.
Final Words & Tips
- Stitch Markers: Marking the sides before placing the fins will help ensure symmetry.
- Color Transitions: Changing color on the last yarn-over of the previous stitch creates sharp color boundaries.
- Customization: Use variegated yarn or alternate stripe sequences for unique designs. Add beads, sequins, or embroidered details for extra flair.
- Washing/Care: Hand-wash your amigurumi gently; avoid excessive scrubbing.
Conclusion
Your seamless, double-striped, and beautifully proportioned fish is now ready! This quick and clever project requires no sewing of the fins, is perfect for gifts, decor, or personal charm, and can be endlessly customized. Enjoy crocheting your school of colorful, cheerful fish.
