My Brother had to get rid of His chameleon and ive had Him for 2 days now, he set it up the way it was at his house and has had it for a year now without any problems, I put an extra branch in so he could climb and moved a vine so he could use that for climbing as well, He was active and seemed happy and is just getting over his shedding, he then come and sat on the vine right in front of the cage that is at middle height and hasn't moved since, His color hasn't change apart from the Tip of the Casque that has gone a gray color last night the temp dropped to 70 and is now back to 90 but he still wont move and looks like he just wants to sleep. im getting worried a little as last night he was rubbing his head in the mesh at the top where the light is and now its gone another color and just dosnt look right, any help please would be great, many thanks.
