Torches touching other torches

[kartrsu]

I have a Malaysian 24k torch that I absolutely love. The rest of my torches are Indonesian. Well, they played nice for a good while until a few months ago where the tips started sticking to each other and the Malaysian pulling back. Any ideas why this would happen all of a sudden? Can they revert back to being friendly neighbors? Could an addition of soft corals or act of stinging encroaching neighbors be causing some sort of aggressive response?
