Well, as much as you hate it, most corals will react if and when you touch them. You can't change the nature of the beast. If you hate the way the leather looks when you touch it, you'll hate it even more if you frag it. If you don't return it to the lfs, just leave the coral alone. It's still adjusting to your tank and the more you handle it, the longer it will take to settle in. Just leave the coral alone and prop it against your rock work if you're concerned about it leaning.
