Too much anthelia?
 

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?

I would say it's preference.

Until it starts to smother other corals or take up too much space, you can leave it and trim to your liking. Some people like to make it grow on the tank wall.

that looks pretty cool, a living wall. I've heard of the same thing with GSP's.

I don't think you can ever have too much...
