Hi guys. I have a newly adopted 4 year old beardie, Chomper, who I have had 5 days now. He is doing well and seems to be settling in overall but I am still trying to learn his specific behaviors and make sure I have my lighting and temperatures set right. He is in a 40 gallon breeder. He has a basking rock cave that sits on. The platform is about 9.5 inches from his basking light. I have been using an Nubee infrared temp gun to measure temps. His rock at various spots is 93-98. I have a 75 watt halogen bulb in his basking light and also run at Reptisun 10.O T5 in a nano tech reflector fixture which sits on top of his screen lid. A concern I have is he is still having periods of gaping while sitting on his rock. Do I need to change out bulb to a 60 watt and lower his basking temp? I am struggling to figure out how to keep his temps stable where he is getting all the heat he needs but not too warm. He will shift positions on his rock for lighting needs. Another concern is he rarely goes to the cool side of the tank. My cool side reads about 81. Tank has plenty of ventilation. I really appreciate the input. Have done a lot of research prior to bringing him home and trying very hard to make environment one he will enjoy and thrive in.
