Large bristleworm bothering anemone?

[Quinn]

So as you may or may not know, I have an M. doreensis that has never eaten and recently has been moving a wee bit and not digging back into the sand. I was worried it wasn't happy because of flow, lighting or because I wasn't giving it exactly what it wanted to eat. The other day, however, I observed a very large bristleworm coming out from under the rock the anemone is in front of. Tonight I saw the worm again, this time basically under the anemone. I am wondering if the worm is bothering the anemone, hence why it keeps moving or making like it is going to move and refusing to dig in? I could easily relocate the anemone if that is a good plan or I could leave it - there is no way I will be able to get at that bristleworm though. Any thoughts?
