Hi Im new here and I just have a question to ask all of you i bought a yemen chameleon at least a month ago and since ive had him he has been very friendly and happy, but over the past few days he has becom very unsociable towards me, he is either aggressive or scared, he opens his mouth and puffs himself up when i go near him and he will change into a dark brown/ green colour with black speckles and other times he makes himself flat and brown and doesnt move at all. Im just wandering if this is normal for chameleon behavior as this is my first one or he/she is just maturing into an adult or if its simply to with stress and i should leave him/her alone for a while or maby because of deeper problems. He/she just shed and i thought that could also possibly cause the problem. If any one has any comments im all ears and they would be much appreciated thank you.
