My apologies if this is posted in the wrong section.

I got my frog about 5 days ago and he has not eaten since. He is being kept in a "critter keeper" that's a decent size while I wait for his nice terrarium to arrive in the mail. The problem is the pet store only had large crickets that were way too big so I have been trying to tong-feed him mealworms as he hasn't moved since I got him and I don't want them to borrow. He doesn't run from it he just starts beating his throat really fast (don't know what that's called but I assume that a fear response). He'll have a proper home in about 3 days but I'm afraid that he still might not eat due to the small enclosure. I'm heading out now to see if that have small crickets. How long can they go without eating? Me being a tarantula guy, i'm used to weekly or sometimes even monthly feeding for my spiders, but have no general idea about frogs.

Also can someone recommend a very good care sheet or just post the general heat/humidity requirements? I'm reading a few which contradict each other.
