Frog People!

I come to you again in hopes of a solution! I posted a week or so ago about my new RETF not eating. So, I decided to let it go. Viv is good, stats are good (as far as temp/humidity), and he seems to like the setup of the tank--he explores every night after the lights go out.

Now, how do I get him to eat!? The past few nights I have noticed him perched up on a vine that sits right next to the bowl that holds the crickets--usually 4-5 each night. However, each morning, once again, they are all there and he is back asleep under a giant leaf that he seems to love.

Upon further speculation, the reptile shop that I got him from doesn't seem to take care of their animals very well and it got me thinking that the probability of him being wild-caught was pretty high. That being said, do you think this is why the bowl seems to intimidate him? Should I remove the sphagnum moss and only leave the eco-earth until I see he is eating? (I'm afraid of the crickets hiding and dying in his viv).

Please help!
