I run to UTH's on my tank so I have two accurite gauges inside. Hot side by water bowl reads mid 40's humidity, cool side reads 56. Should I try to increase some or leave that as is?

My new girl has been fed live so want to stick with that at least for the first few meals. I've never done live feeding so my question is- if she doesn't eat what the heck do I do with it? (Rat pup/fuzzy)
