Mike, unfortunately most pet stores employees have no clue about frogs and proper husbandry for each frog. You have been told at least some proper things, but we see so many threads here of people asking to help their dying or very sick frog, you look at their answers and that they say that's what let store told them, and getting extremely mad at pet store people for that. Funny part when they give you a care sheet and ask you to sign that you've read and going to follow. Last time i had to do that i wrote ive read, but not going to follow and asked to see their manager sometimes it works, most of the time it doesnt.

anyhow... Pet stores.... I can go forever on these lol

humidity - what is a problem? What is your humidity and temp now? What gauges are you using?
