WHOA! Just spotted a huge freaky looking worm in my reef!!!

That son of a ***** was fast and strong too!!!!!! I'm freakin out a little bit. Gave me the hibie-jebies big time!
So my RBTA's have their tentacles all elongated trying to grab food particles, so I figure, I'll feed them each a silverside so they don't bother the corals around them. In the frag tank, there is a couple, and I come back 30 minutes later, and there is a yellow looking worm about 4mm in diameter and I'm guessing 15cm long! Maybe longer! I whip out a pair of tweezers and grab him, put a hell of a pinch on him and he slides powerfully and easily out of my grip and zips halfway across the tank ~16" into a large rock. I get a second grip on him, but it's too late, most of his body is in the rock, I pull and try to wrap his body around the tweezers for extra leverage, and zip....he's gone. I have no idea what this thing is! Freaky as hell!
I'll keep ya updated!

 

no...I don't think it was the peanut worm. It was yellow though. Looked more like this one:

I can find this picture in google images but I can't find any dialog about them. Is this just some type of bristle worm?
Jim you didn't take a picture of that thing!? Sounds crazy. Yeah I think we all get a little uncomfortable in our skin with these things!

 

There's no way a six line can eat this thing. I have a 5 yo sixline that is 3" and he's dwarfed by the size of this worm! lol

 

That hitchhikers guide is really sweet! Now I just really want to catch the damn thing so I can ID it!

 

GOT HIM!!!!!! or maybe just one of them. This one doesn't look as big, maybe 5-6" max, or maybe my imagination was just running away with it. Maybe there are more in there ughhhhhhhhh!!! Here ya go:


Damn I love this lens! Let's take a crack and figuring out what the hell he is huh guys?

 

I just realized that the bastard stung me or something. I grabbed him with my fingers and the tips of my fingers are literally black and blue. I can actually see segment pattern in the bruise. You have no idea how hard it is to take a picture of your own index finger and thumb; The bruising looks much worse than shown;
