So I do know what gaping is and I know I don't see my chameleon 24/7 in the 4 months I have owned him have only ever seen him gape once. I come home from work see picasso on his baskking branch mouth slightly opened been a few hours ssince his last mist so do that to maybe cool him down. Before I did so my temp gun read 83.5F. Mention it to my mom said he has done it a few times today. Now an hour later seen him doing it again. Bottom of the cage at the time was 69.5 (therm probe) mid was 75.5 (probe) basking 85.5 (temp gun). Temp gun on him read 89. His mouth never stayed open for extended period of time. Been a a little while since his last she'd as well. If you think it's beneficial for a how to ask for help form I will. Took a pic of the mouth opened and zoomed in, in case that may help. He's 6 months old.
