My crested gecko Lex's home is a planted vivarium, and I somewhat regularly switch out the plants depending on what thrives, what she likes to interact with, what is available for a good price, and so on.  Quite a few months ago, I put a small Dracaena (I think perhaps Dracaena compacta but I'm not 100% certain) in her tank.  Lex is always suspicious of new tank additions, so while I know she acclimated enough to tolerate being around it some time ago, she's now finally decided it's actually trustworthy and quite comfy to boot; here's a few shots of her latest sleeping position.  Crested geckos are nocturnal so she mostly sleeps during the daytime; they also don't have eyelids so while she looks to be awake in these photos, she is really either fully asleep or drowsily wondering what I'm doing poking a camera lens in her face.
