I took a serious look at several different species of geckos. From what I recall:
1. Most of them are
crepuscular (depends when you want to observe them active)
2. Most species "bark"—at night (can be annoying to some)
3. They tend to drop their tails—often with little/no reason
None of those facts should dissuade you; they might make a difference, or might not.
Just stuff that stuck in my mind from researching lots of 'em.
I don't recall the specifics of gargoyle geckos, though they were high on my list. It was over a year ago, but I still have cards & impressions from quite a few breeders (Northeastern US).
Ooo good intel on them being at the dollar store! This looks better, no? I dumped out nearly all of the small rocks before adding these in.
I think they look better, but it's your enclosure!
I started using the pebbles for my beardie enclosure. I wanted to use live plants, but didn't want them raising the humidity, and I didn't want Ol' Stinkeye digging them up (as beardies are wont to do...

) The pebbles work—they keep too much moisture from evaporating, and so far (fingers crossed) he hasn't dug any up in a year, though he's eaten and/or destroyed
many.
