1 month isn't enough time for him to adjust. If you that him well and interact with him a lot in the year it should be 100% used to you, if not sooner. Of course this all depends on its personal temperament, may always be scared, probably not though. On the bright side, if he's a bit timid he won't eat your tank mates lol. My old black aro couldn't stand it if you looked at him head on, he would only ever look at me sideways. He was real used to me and when I tried he would tilt his head one way, so I followed him that way and he would keep shaking his head around everytime I did that but never actually got scared or nervous or anything like that. Was funny to mess with him. You'll be fine bro, but upgrade soon plz.
