Mine have their food dishes at ground level. The dishes are placed on something to raise them off the floor a wee bit, keeps the substrate from getting mixed in. I've used small chunks of marble, slate, tile, or the like. For hatchlings, I put the dish (a lid) inside a coconut shell. There's enough room to cling to the inside of the shell while eating.
Even wild ones will eat down there. Bugs don't always climb up trees and shrubs. They eat overripe fruit, which, in all likelihood, has fallen to the ground.
As for the tank being too big, it's pretty much impossible, considering how well the manage in the wild, which is a much bigger area than we give them. Check this thread for more info: "

If hatchlings can manage to find food in a 55 or 65 gallon enclosure, I'm sure an adult won't have any problems managing in a 30 gallon enclosure.
