I wanted to know if there is anyway possible to tell how old a crested gecko is?? As in if the younger cresties are more active?? or if the older ones eat alot less?. My crestie i can barely tell that anything is gone out of his dish. But i do as alot of people do i am modering him and i make sure he has fresh food everyday if not every other day. I am misting in his tank nightly.. I have a fishtank temperature gauge in there and it seems to be doing the trick. It is staying in the green witch is the right temperature. I have a humidi gauge and it stays between 45-60 degrees. He has not shed since i have gotten him and that was almost 1 month ago. He is very calm when i hold him but does tend to try and fly when he clearly cannot (i do catch him all the time). Can someone help me figure out as to why he is not eating much CRESTED GECKO DIET?? Or not shedding, or not drinking much??
