I hate to be a bearer of semi-bad news, but that is a Tarentola annularis (White-Spotted Gecko). Definitely not a Rhacodactylus.
Not from New Caledonia. It's from Sub-Saharan northern Africa. It needs a drier setup than you have there. Strictly insectivorous.
I think your setup will work just fine, if those are mainly artificial plants. Just lower the humidity, and raise the heat a lot, if you were keeping it like a Rhac. (More heat is the most crucial thing).

I would be curious to know if you had it eating CGD or fruit, and if it actually ate any, lol.
