Filter Feeder in a Acro?

[reefnut]

I got some new corals on Friday. Today I noticed some kind of filter feeder living inside a acro. The hole is oval shaped... any ideas?

If it is feather-like and darts in and out of the hole I would guess a barnacle. Tough to say without a pic though.

I posted on the other board and I think it is infact a barnacle. Here is a pic they posted...
I was told they are harmless but I'm very concerned because I do not want it to spread.
Any thoughts?

I have had several acros with barnacles within them. Most of the time the barnacle eventually dies and is overgrown by the coral.
I would be surprised to hear that if it is in fact a barnacle that it would either, not co-exist with the coral or would "spread" and cause a problem.
If it starts to keep you up at night you could always remove it and the area should grow over in no time.

Thanks for your help SiF. Just needed to hear it from someone else.
