Is Loose substrate for hatchlings kept on live insects a Safe Substrate for Mourning Geckos?
A hatchling hunting fruit flies on loose substrate can occasionally ingest particles along with prey. Use paper towel for very young geckos until established, switching to bioactive substrate afterward.

Yes. Coconut fibre (eco earth) + sphagnum moss topper is a safe substrate for mourning geckos. The standard for a humid bioactive mourning gecko setup.
Yes. Paper towel is a safe substrate for mourning geckos. Best for hatchlings, quarantine, or a simple non-bioactive setup.
Yes. Sphagnum moss (as primary layer) is a safe substrate for mourning geckos. Excellent moisture retention for a humidity-dependent tropical species.
Use caution — Reptile carpet is rated "caution" as a mourning gecko substrate. Retains less humidity than coco fibre and can harbour bacteria if not washed frequently.
No — Sand is rated "avoid" as a mourning 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 mourning gecko substrate. Sharp edges can lacerate the digestive tract and cause severe impaction if ingested, and are far too large-grained for an animal this size regardless.
