You have a cute little one there. He is also really skinny. When I first brought Buddy home he didn't really want to eat a lot either. Like Cooper said keep trying. Make sure the bugs you feed him fits between their eyes. I notice Buddy won't go for small things now. I put a small cricket in the vivi and he looked at it and then turned his head. I personally use a T5 bulb from Arcadia and it sits right on top of the cage along with a 100W heat bulb. While in the bath Buddy doesn't seem to want to drink he only wants to swim, poop, then get out of the tub.
