Thanks everybody! This guy reminds me of a fantasy I had years ago, as far as eating. He ate two crickets last night, obviously when I wasn't looking. The only reason I'm reluctant to move him into a paper towel setup right now is because I'm leaving the country in a week for a few months and my wife will be taking care of him. She has some horned frog experience but only with adults. I'm thinking that if he feeds on them in his setup at night she could keep it up easily while I'm gone.
Also I have changed out his water bowl for a much smaller one, in case anybody was wondering.
