Zoo Med Mixed Fancy Crab Shells 24 Counter Display
A shell shop your hermit crabs can browse themselves. The Zoo Med Mixed Fancy Shells 24-piece display (model HC-40) is an assortment of natural, unpainted hermit crab shells in mixed shapes and sizes. Land hermit crabs change shells as they grow, and having a genuine choice on hand — rather than one uniform size — is what lets them find a proper fit.
Suits multi-crab enclosures and any setup where crabs are due to grow into a new shell.
Key features
- 24 shells per display — a genuine range of shapes and sizes rather than one uniform shell.
- Natural, unpainted shells — no dye or coating to flake off or affect water or substrate chemistry.
- Lets crabs self-select — hermit crabs test-fit shells themselves, and offering several options reduces shell fights in a shared enclosure.
- Counter display format — 24 individual shells packaged together.

What's included, and what you'll still need
Included: 24 individual natural hermit crab shells in assorted shapes and sizes. Zoo Med doesn't publish an exact size breakdown for the mix, so expect a genuine range rather than a guaranteed count of small, medium and large shells.
Suitable for, and not suitable for
Suitable for land hermit crab enclosures housing more than one crab, or any setup where crabs are due to grow into a new shell. Not intended for aquatic hermit crabs. A crab that can't find a shell that fits in this mix may need a properly sized replacement bought separately.
Care and maintenance
Rinse shells before adding them to the enclosure. Offer several sizes at once rather than one at a time — crabs are more likely to test-fit and settle without conflict when there's a genuine choice available.
Warranty and delivery
A natural product; Zoo Med doesn't publish a warranty term for shells. Standard shipping applies.
Common questions
How do I know what size shell my hermit crab needs?
A good fit sits close to the crab's body with room to fully retreat and close the opening with its claw. Offer a few sizes from the mix and let the crab choose.
Are these painted or dyed?
No — this is a natural, unpainted mix. Zoo Med also sells separate neon and glow-in-the-dark shell ranges if you want a coloured option.
Can I use these alongside other hermit crab decor?
Yes — shells are a standard addition alongside substrate, humidity hides and climbing decor in a land hermit crab setup.
Why offer more than one shell at a time?
Hermit crabs test-fit shells and can fight over a single desirable one. A genuine choice of sizes reduces that competition.
