Is this thing bad?

[alvin]

So I noticed this red "coral" type thing on a few of my live rocks. I did some searches and I think it is called a "Homotrema rubra"?? I tried searching, but no luck. I did find a pic on line, but no real information. So should i try to take these bad boys out or what.

Thanks in advanced for your help.

I've always heard that they are harmless filter feeders.
