Hi, I am new to the forum but not to keeping a panther chameleon. In fact, this is my second panther after my first past away on November 1, 2011 at 5 years of age. My first panther is very docile when I first got him when he 3 month olds, but this panther keep on hissing at me. Does he calm down as time passed? He is 6 inches long from head to tail. He just arrived today from chameleon company. I think something is wrong with his tongue because he cant stretch it out to catch his prey and have to be very close to his prey and keep on missing. Help would be appreciated.
