Worm on lurking Goniopora

[Aqua Splendor]

I'm not a worm nerds, I'm having difficulty to ID it, if anyone know let me know!
It's a "common one" but just looking for its real name.
It's a worm that is insanely fast once its touched.
The goniopora have no apparent hole, I think they go through the tentacle/skin maybe.

Some type of worm.....

I am having issues identifying this little worm in my tank.... I have been doing research and looking all over because it is IMPOSSIBLE to get a picture of theses dang things... I found some pics online that look very similar and just wanted to shoot them out to see if anyone has any ideas...

In this case, those both look like Syllid worms to me:

Based primarily on the long, hair-like chaetae (bristles) sticking off the sides, I’d guess a Syllid worm (taxonomic family Syllidae) of some kind. If it is a Syllid worm, then there’s a good chance it’s safe (and good CUC). However, some Syllids are known to eat sponges, tunicates, and - reportedly from some hobbyists - soft corals. The eating of soft corals is firmly disputed though, as many people (primarily from several years back, when Syllid worms were apparently more common hitchhikers) also report having them without issues even if the worms crawl over their soft corals regularly.

So, it’s probably safe/beneficial, but you can always sump it to be cautious, you could isolate it and offer it a cheap soft coral or two in addition to some fish food to see if it’s coral safe.

Some context for their diet (the paper linked below is “The diversity in diets of Syllidae (Annelida: Polychaeta)” by the università di lecce (the University of Salento).
