Switch to nightcrawlers, don't give up. Coax him by rubbing the nightcrawlers on his bottom lip. I've noticed that when I changed all my frogs from locusts to nightcrawlers that they pooped alot better.
Thanks, I have the nightcrawlers and will try....but it will not be in his cage. No more substrate in the mouth.(:
