Since sandfish skinks are native to some of the driest areas in the world, they don’t need much in the way of humidity. This is one of the reasons why they’re some of the easiest reptiles to keep! That being said, like every other living thing on Earth, they do need water. In the wild, sandfish will seek out areas of higher humidity such as near small bodies of water, under rocks, or pockets of moist sand as needed.
Recreate this in your sandfish’s enclosure by drilling a notch into a thin PVC pipe, and then inserting it vertically until the notch is touching the bottom of the enclosure. Regularly trickle water through this pipe (about once a week or every other week, depending on how fast it dries out) to create a damp layer of sand at the bottom of the enclosure.
Alternatively, you can use a sheet of PVC or stone tile to partition off about 1/4 of the sand, and then keep this area moistened via misting with distilled water. I find using a pressure sprayer like the Exo Terra Mister very helpful for this.
You must also provide a shallow bowl of water for your sandfish, just large enough for it to be able to lay in the dish if it wants (although this is rare). It should be no deeper than 1”. Use tap water or purified drinking water, as distilled or R/O water is not safe to drink. However, distilled and R/O water is ideal for misting.
