Hello, I am a new owner of a chameleon. He seems to be about a week or so old, I'm not too positive. I have him in a 10 gallon tank but I plan on going to a bigger more ventilated space when he gets bigger. I have a dripper a heat and UVB source (they are both in the same light) I have various areas where he can climb. I mist 3 times a day, I also make sure the temp is between 72-80 and the humidity is 50-80. So why is my chameleon always dark? He's bright at night but during the day he's either brown or jet black. Is he too hot/cold? Is he just stressed? Plz help! I know he's green in the pic but he normally isn't.
