Is Walnut shell a Safe Substrate for Crested Geckos?
Sharp edges can lacerate the digestive tract and cause severe impaction if ingested. Avoid entirely.
See the full substrates guide, or browse all 440 info pages.
Yes. Coconut fibre (eco earth) + sphagnum moss topper is a safe substrate for crested geckos. The standard for a humid bioactive crested gecko setup.
Yes. Paper towel is a safe substrate for crested geckos. Best for hatchlings, sick geckos, or quarantine.
Yes. Sphagnum moss (as primary layer) is a safe substrate for crested geckos. Excellent moisture retention for humidity-dependent species.
Use caution — Reptile carpet is rated "caution" as a crested gecko substrate. Retains less humidity than coco fibre and can harbour bacteria if not washed frequently.
Use caution — Loose substrate for hatchlings feeding on crickets is rated "caution" as a crested gecko substrate. A hatchling hunting live crickets on loose substrate can accidentally ingest particles along with prey.
No — Sand is rated "avoid" as a crested gecko substrate. Not suited to this species at all — wrong humidity profile for a substrate that needs to stay damp, and carries an impaction risk if ingested with prey.
