Currently 77F on the cool side and ambient 72F. I currently only have a hide on the warm side, but no nothing has changed at all. I changed the aspen last week, but I didn't think that'd be a big thing.
you also need a second hide, and try to raise his ambient temps up to at least the 80's IMO, i know anything 75 and lower can be dangerous
until you can get another hide, i'd put his right in the middle, so hes neither hot or cold, that might help
