Too much anthelia?

[DanG]

My story starts out like most people who have anthelia or zenia. You get a small frag of a couple of stalks from someone, and next thing you know, it's everywhere.
As it stands, it's not covering any of my coral, not blocking anything, just growing, longer, thicker and over more rocks. I don't have any aversion to it. Is there a problem that I'm not seeing with it? Or is it a personal preference on how much to keep?
