ID invert eating my trumpet coral

[Dashylock]

I noticed that part of my trumpet coral is bleaching inexplicably and then I saw this invert that seems to have taken refuge in a dead polyp. You can see its two antennae. Any ideas what it is and how I get rid of it?

Does it look like a worm at all?

My other guess would be a harmless stomatella snail, but it's really hard to make out anything from that picture. (sorry)

Too difficult to tell anything from the photo.
