Trying to confirm these are Spaghetti worms.

[Loring]

I have these little sand tubes popping up in the my substrate with some sort of worm that sends out one maybe two long white tentacles. The second pic you can see the white line it's sending out laying on the substrate. Seems to be some debate on other threads if these are spaghetti worms or not so trying to narrow it down. Only issue I really have is a couple of them are irritating my zoa's and keep causing them to close up. This in an Evo 13.5 so I'm wondering if besides manual removal if possibly a pigmy wrasse might try to calm the little outbreak I'm seeing? Of course if this something different please let me know. Thanks for the help

Spionid worms, good thing to have and most likely not the root cause of your issue

Ok good to know it's nothing to really worry about and I would agree with you except I physically watched them squirm their little tentacles on my daisy cutters last night which just irritated them I think and caused them to close up briefly. I knocked down the tube that was right under them but I was thinking of a pygmy wrasse because I have a pretty awesome copepod population on accident (not mad) and was wondering if it would go after these guys too possibly.

I don't think a wemorella would go after these guys and I probably wouldn't recommend getting one for that small of a tank. If you had a 25g - 30g mature tank with plenty of live rock, then maybe that would work? Wetmorella's will eat prepared foods, but they mostly eat live foods/prey items. The worms shouldn't bother the zoas too much, but you can always remove them with a pair of tweezers, just pinch behind the opening and you should be able to grab the tube.
