Brittle worms

[Salt4Us]

My Pipe Organ Coral has a small brittle worm living in it, I just saw it this morning when I was feeding the coral, I've noticed that in one spot the polyps are droopy, usually when I see this it tells me they are hungry and I feed them and they perc up. There is only one section that won't perc up and I've noticed grooves in the coral that hadn't been there before. My question, can anyone suggest how I can get rid of the brittle worm, we also have a rather large one but it mainly stays low (that I know of) I'm sure there are other worms just haven't seen them. I don't want this coral to die.

Thanks

I've also seen my peppermint shrimp all over it, anyone know if peppermints eat or can damage pipe organs? Thanks again
