Thanks for the reply!

Just seeing this now so I'll attempt to remove the stuck shed tonight. Other than the wheezing, he's not showing any other signs of an RI. No mucus, open mouth breathing, stargazing etc. He's showing normal behavior i.e. hiding/asleep during the day and active at night. Not sure if that matters with regard to the RI.

I bought a bag of cypress the other day which I'm planning to mix in with the coconut fiber when I do a full clean down (most likely this weekend). If that doesn't work, I'll try some damp sphagnum moss.

As for CHE/UTH and temps, my UTH is hooked up to an On/Off type thermostat so the temp does vary slightly from 89-92º. I know ambient temperature is preferential regarding a gradient or constant throughout the enclosure. My issue is that without the CHE temps get down to around 77º throughout the enclosure. If I get a dimmer what temperatures do you suggest I keep my ambient temperature on the warm side at?

Thanks again for the help!
