Thanks everyone!!
Like most Rhacodactylus geckos (cresteds and gargoyles are both Rhacodactylus species), these guys are fruit eaters. They will subsist almost exclusively on overripe and rotting fruit in the wild along with a few choice soft-bodied insects and grubs.
In our homes, these guys can eat Rapashy's Crested Gecko Diet exclusively which is one BIG reason I was looking into these guys (Yeah! No bugs!). And I can give him the occasional piece of banana or peach or whatever as a treat.
He is already eating out of my hand.....![]()
