Identify please

One last question. I had a couple of things growing on my euphyllia coral stems. Also some fishing line sized worm looking pests on my live rock that I took a polyp off of. Are these pests to be worried about? Thoughts? I really need some input, thanks!

Spirorbid worms- harmless filter feeders in the first.

Vermetid worms are those purple/white tubes- they can get to plague proportions so I would super glue the opening of their tube to starve them out.

Last pic seems to be a spaghetti worm, which is another harmless detrivore.
