Coral/worm need some help here O.o!?

Ok I have a few bristle worms in my tank maybe 4 most not that big but there are(were) at least two that when I saw made me a little worried about my corals even though many people have said they are not a threat. Well one night when I was up late playing FFXI I saw one of the bigger worms sort of climbing the glass. I thought that’s kinda odd but went on playing my game. Next time I look over he/she/it is gone I totally freak out, what if it got out and is going to eat me in my sleep or crawl into my head and lay eggs(im paranoid like that) anyway I get up to check and it had just fallen but it had fallen into my bubble coral I had no idea what to do it looked like the coral was eating it. So I thought ok that’s prolly fine it must happen all the time in nature. Next day I wake up and my coral is looking dull and limp and kinda lop sided. So again I freak within the next few hours it almost looks like the coral is dieing or its throwing up I don’t know. Just need some help here will my coral be ok I really like it :sad: also if I see another one of these worms should I just get it out of my tank?? Please help :bowing:

Well it looked limp with some lose of color right when i woke up but i have had this coral the longest its my favorite and im used to its daily rutein. Thats why after 2hr when i looked back and saw it still was limp and its mouth was kind of lop sided (like it was vomiting) is when i wrote you guys for help.

Ok everything seems back to normal Thank you for the help
