Question about pests

[mlsund]

I have a 2 sets of acropora frags and i am trying to figure out if one of them is infected with something.

Where the polyp normally extends on my brown acropora there appears to be two microfine antennae or thread like feelers extending on some of the polyps.

is this part of the coral or is it a worm of some type?

Its a worm that lives in many corals. They are pretty harmless.

Thanks sjfishguy I was wondering if i should panic or not.
All of my frags are growing well with no discoloration so i guess everything is normal.
