Why is my Crested Gecko sleeping under Substrate?

It’s quite common for Crested geckos to sleep under their substrate sometimes.

They are semi-arboreal, meaning they like to climb, but they also feel secure in enclosed spaces.

Sometimes, if their tank is too warm or not humid enough, they might dig to cool off or find a more humid spot.

So, they do this mainly to control their body temperature and feel safe.

Should I Be Worried?

In most cases, sleeping under the substrate is normal behavior.

But, if you notice any of the following along with the burrowing, it might be a sign something’s wrong:

  • Loss of appetite
  • Weight loss
  • Lethargy
  • Difficulty shedding

If you are concerned about any of these issues, a visit to a reptile veterinarian is always recommended.

Hope this makes sense!
