Possible feather dusters on my zoas?

[Snailfood73]

Could anyone give me an id on these worms growing on my zoas? Up until now, these zoas were by far my most hardy. Rarely have I ever seen them closed. Now these little tiny tube like worms have started to take over the plug and I think the zoas are starting to get irritated. The tubes don’t move at all and I can’t see anything coming out of the tubes but they’re definitely multiplying over the zoas. What do y’all think these are and if they are harmful in any way, how can I get rid of them? (unfortunately the zoa plug is superglued to the rock work so I don’t think I will be able to dip them in coralRx) Thanks!

I see both poriferan sponge and tube worms which emit fans for feeding
Easiest way to rid of them is to direct water flow towards them- not at them and they will soon starve
