My pet Whites tree frog?

Sounds like you are doing everything the way I did... Mine ate a little more, but I would put a few in at a time. Do you have a humidity gauge too? Mine also seemed pretty lazy at times.. we also used moss and it was suggested we use coconut bark which worked out well. i cleaned his tank a lot cuz he use to have slime all over which i would sometimes have to scrape off with a razor blade. just give him what he needs food, heat, humidity.. ours lived for 11 years...
