Is this is a common bristleworm

So i tried very hard ro keep these outa my tank. But i guess they got in anyway. Noticed a long like 6 inch one at night the otherday but it ran when i tried to grab it with tweazers it was strong too.

I just dipped one of my favia colonies in api general cure which has metronidazole and prazi pro in it and some doxycycline antibiotics in an effort to try to stop whatever is killing my favias. Suspecting baterial not sure.

And this big worm cane outa the rock. Looks like a common bristleworm. It died in 5min in my dip.

Yes looks like a common bristleworm. Not really bad as they eat detritus and their numbers self populate based on food supply.
I suck them out from under my baskets and frag tiles where detritus collects when they get too big or too many.

Not certain, but I believe its just a bristle worm. Trying to find a resource for you now.
