Easy Crochet Fish Keychain Amigurumi Pattern for Beginners (Cute Mini Sea Creature DIY Guide)

Skill Level

Beginner-friendly.
You only need to know how to:

• Crochet in the round
• Increase and decrease
• Sew a few small parts

The YouTube video linked in the reference URL is a helpful visual guide for assembly and placement, especially if you’re new to attaching fins and adding a keychain loop.

Materials

Choose smooth yarn for crisp stitches, or plush/chenille for a softer “squishy” fish.

• Worsted or DK yarn in 2–3 colors (body + fins + accents)
• Small amount of black yarn/embroidery thread for eyes (if not using safety eyes)
• Small amount of white yarn for eye highlights (optional)

Color ideas that look great in photos: coral + white, teal + yellow, rainbow ombré, or classic orange “goldfish.”

Hook Sizes

• 2.5 mm to 3.5 mm hook for DK/worsted yarn (pick a smaller hook than the label suggests for tighter amigurumi fabric)
• If using plush yarn, try 4.0 mm to 5.5 mm, and focus on tight, even stitches

Other Supplies

• Keyring or lobster clasp
• Stitch marker (or a scrap yarn marker)
• Stuffing (polyfill)
• Yarn needle (tapestry needle)
• Scissors
• Optional: safety eyes (6–10 mm depending on fish size)
• Optional: jump ring (makes the keychain attachment sturdier)

Key Abbreviations (US Crochet Terminology)

• MR = Magic ring
• ch = Chain
• sc = Single crochet
• inc = Increase (2 sc in same stitch)
• dec = Decrease (sc2tog; invisible decrease recommended)

• FLO/BLO = Front loop only / Back loop only

Special Notes

• This crochet fish keychain amigurumi pattern is designed to be fast and easy to customize.
• Work in continuous rounds unless stated otherwise.
• Use a stitch marker to track the first stitch of each round.
• For a cleaner look, use invisible decreases and stuff firmly so the fish keeps its shape.
• Since your scrape didn’t return transcript details, the stitch counts below are a beginner-safe original pattern inspired by the “small, colorful fish keychain” concept shown in the video and image context—no content is copied from the source.

Step-by-Step Instructions

Body (Head to Tail Base)

Start with your main body color.

Rnd 1: MR, 6 sc (6)
Rnd 2: inc around (12)
Rnd 3: (sc, inc) x6 (18)
Rnd 4: (2 sc, inc) x6 (24)
Rnd 5: (3 sc, inc) x6 (30)
Rnd 6–8: sc around (30) for 3 rounds

Shape Toward the Tail

Rnd 9: (3 sc, dec) x6 (24)
Rnd 10: sc around (24)
Rnd 11: (2 sc, dec) x6 (18)
Rnd 12: sc around (18)

Add safety eyes now if using them (place them around mid-height of the head area, about 5–7 stitches apart depending on your preferred face).

Start stuffing the body firmly.

Rnd 13: (sc, dec) x6 (12)
Rnd 14: sc around (12)

At this point you have a cute “mini fish capsule” with a small opening that will become the tail base. Add a bit more stuffing, but leave room to flatten the tail end slightly.

Tail Fin (Simple, Cute, and Flat)

Switch to a fin color (or keep the same color).

Flatten the final opening so it sits like a little “mouth” of stitches. You’ll crochet through both layers to close, creating the tail fin.

Tail Row 1: sc across 6 stitches through both layers (6), ch 1, turn
Tail Row 2: inc, sc 4, inc (8), ch 1, turn
Tail Row 3: inc, sc 6, inc (10), ch 1, turn
Tail Row 4: sc across (10)

Shape the forked tail:

• sl st into the next stitch, ch 2, sl st into the same stitch (creates a small point)
• sc 3, then repeat (sl st, ch 2, sl st in same stitch) for the second point
• sc to the end, fasten off and weave in

If you prefer an even simpler tail, skip the “points” and just crochet a small fan shape.

Top Fin (Make 1)

Use fin color.

Rnd 1: MR, 4 sc (4)
Rnd 2: (sc, inc) x2 (6)
Rnd 3: sc around (6)
Fasten off, leave a tail for sewing.

Sew it on the top/back of the fish, centered, about 1–2 rounds behind the eyes.

Side Fins (Make 2)

Use fin color.

Rnd 1: MR, 3 sc (3)
Rnd 2: inc around (6)
Fasten off, leave tails for sewing.

Sew one fin on each side, slightly below eye level.

Keychain Hanging Loop

Attach yarn at the top of the fish (slightly behind the top fin looks best).

• ch 12–18 (adjust for your keyring size)
• sl st back into the same area to form a loop
• Weave in ends securely

For extra strength, run the yarn tail through the loop base a few times.

Tips for Beginners

• Tight stitches matter for keychains. If you see stuffing, go down a hook size.
• Use a stitch marker—amigurumi rounds are easy to lose.
• Don’t overstuff the tail end. A slightly flatter tail base helps the fin sit neatly.
• If sewing feels tricky, pin fins in place first with scrap yarn and check symmetry.
• When in doubt about placement, open the YouTube video and use it like a “pose reference” for where the fins and loop look most balanced.

Creative Variations

• Clownfish style: orange body with white stripes embroidered or surface crochet lines.
• Koi fish: white base with orange and black spots random patches look realistic.
• Jellybean fish: pastel body, bright contrasting fins, and embroidered rosy cheeks.
• Striped tropical fish: change colors every 2 rounds to keep stripes easy.
• Glow effect: use neon yarn for fins, or add a tiny sparkle thread strand.

You can also scale the fish by using thicker yarn and a bigger hook—perfect for a bag charm instead of a keychain.

Conclusion

This crochet fish keychain amigurumi pattern is a sweet, speedy project that turns small yarn leftovers into a practical accessory. The shape stays beginner-simple, while the fins and tail make it instantly recognizable and fun. Make one for your keys, a backpack, or party favors—and use the YouTube video as a visual helper for finishing details and assembly.
