I finally found a research journal article w/ a little care info.....get this...80-99 during the day....59-68 F at night....mean body temp of 91.4 F...that was from Eastern Fence Lizards in NJ. I am providing a thermal gradient from about 100 to 76 so I should be ok.....fence lizards must be very forgiving animals....they live everywhere. I will let you guys know how the attempted feeding goes tomorrow. also, the researcher successfully fed dusted crix to the animals in the study....so this guy should be a keeper
