I went a bit different direction than tttaylor, but I'm not any more experienced. I've had mine for about 4 months, and he (can't tell yet ofc) is now around 5 months old. He's pretty small for his age as far as I can tell since he refuses insects (recently I've gotten him to eat 1 or 2 small crickets a month).
I started him in a critter keeper for a while with hand misting while I got an auto mister (set up for the crestie and my husband's giant day gecko) for a bioactive planted 18"×18"×24" exo terra. I moved him in after a month or so when I was sure he was eating and pooping normally and didnt have any issues.
Even as a baby I've seen no issue with him finding his food in such a large tank (although I always replace it late evening when he is active and it smells strongest and positioned his food by one of his most frequented vines to make sure he can get to it easily)
This is an old tank picture, since I don't have a recent one that has a full view. The plants have filled in a lot and we swapped his food to the right side. Don't mind the humidity, it had just misted and spiked up.
