Parasite after 76 days fallow

[Williamson’s Reef]

After seeing Ich... All Fish where treated in QT 30 days copper, Fed GC mixed with focus for two weeks, tanks treated with GC after copper. No signs of Ich again and all poop was normal. Fish went back in DT after 76 days Dec19th. Last night my Naso had a small worm like thing hanging off him. It was brown. I couldn’t find anything on here that looked like. I netted him out and fresh water dipped. It came off but I couldn’t find it in the water. He did splash a lot. Hes back in Qt and I started Prazi. Not sure how he got it... ? I have a purple tang in Qt that has been through the same QT process. He has a worm or something by his scalpel. Fresh water dip didn’t help. He’s never left QT. Any ideas? I also just found these on my sump glass. Are these parasites? I’m really struggling with it all.

It doesn't look like a "fish worm" to me. @Bob Loblaw might be able to ID it.

Are you sure it's not something just stuck to the scalpel? The ones in the sump look like a large species of Spirorbis.

Ok thx guys. I just removed it with tweezers. Doesn’t move. I was a little nervous to do it. But he’s back in the water and seems fine. I’ll look those up.
