I would mist him more than 3 times a day. I would get him a female or two once he's of age. He would definitely enjoy a nice warm shower, just NOT often. A fat Horn worm once in a while would do some good.
I've actually dipped a cricket in some squeezed orange juice straight from the orange. And fed a Dubia with some starwberry guts on it. I don't do that anymore though, but they seemed to be cool about it, and took more.
I'd change up the gut-loads, I mean change to something else everyday. Just make sure your weekly scheduel is well balanced, but give him a variety.
Give your dude ALOT of hiding places.
Does your little guy have a fan in the room he's caged in?
Make sure you don't have A/C or a heater right near his cage.
Never have a mirror in his own sight.
Don't handle him without "NEEDing" to do so.
Offer him his dripper early in the morning for a good 20 min. Than a few more times through out his day.
Make sure the water in his dripper, is NOT too warm, and definitely NOT too cool for his liking/tolerance.
Misting is great for him, especially if it's long enough for him to relax and "soak it up".
Don't leave the bottom of his cage wet, keep it spotless.
Him having the same spots for temperature change is great for him, he should have a consistent routine.
When you do the whole cage cleaning, try to put everything back in place where it was, what he's use to.
Ever tossed a moth fresh from the pupae in his cage?
If he's young you should try cup training him, but as well as free ranging a few. When they're healthy they're active as youngsters. When they're healthy, I'd say they're happy in their home that you provide for him.
But remember, he's NOT in the wild making his own decisions.
