Is Sphagnum moss (as primary layer) a Safe Substrate for Crested Geckos?
Excellent moisture retention for humidity-dependent species. Keep damp, not soaking, and replace if it starts to smell or grow mould.

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.
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.
No — Walnut shell is rated "avoid" as a crested gecko substrate. Sharp edges can lacerate the digestive tract and cause severe impaction if ingested.
