how long does it usually take until a chameleon is used to you. or not nervous around you. my veiled cham is 3 months now, and he is still a little nervous around me. i move slow, and he's in a very low traffic area of my house. he doesn't hiss or turn stressed colored or anything, it just seems like he doesn't like me. i've only had him a little over a week now. and i know that he still needs to get used to things. but i'm just curious to hear from others experience how long it usually takes. thanks.
