So I recently found a garter who hitchhiked on my fishing stuff one day. Did research and decided to keep her. Had her in a 2.5 gallon plastic terrarium at first and while she seemed okay in there I wasn't able to get great temp gradient and I've read that they generally stay more active in a bigger terrarium which means less stress and better health. Problem is I'm still have problems I think getting it all right. I tried a couple of thing and now am trying a 40w blue bulb with a cheap light focuser (the kind you use for car work). My ambient temps are about 78 on cool side and 88 on warm side with this setup which seems fine. But using my iphone flir camera (one of the perks of being an energy inspector) I'm getting readings about 100-101 in the center of the basking light which is focused on the hot side hide. Is this too much? I'd imagine there are plenty of rocks in his natural habitat here in central Texas that easily hit those temps on hot days but then I don't know if they really like basking on something that hot or not. Am I just about right on my setup finally or do I need to move the tank someplace where I can elevate the basking light a bit?
