ID Bad Thing that killed a frag!

[Whitebird1]

Second time i have seen this, seems to make a tunnel made out of membrane also using small pieces of deb re, up to the frag and the frag is dead now. Happened over night!
Last time I was able to take the frag out and scrape it away, it left a scar, like it actually ate the corals outer shell, never found the bug.The pics show the tunnel, splitting in two each ending at the frag head. i had to darken the pics to show it.

Think this is it!!
"Dude thats brown jelly. It f@#%^&g s@@ks and kills s@@t overnight. I just went though a big fight with it, lost 80% of the euphyllia in my tank from it."
And-
"i don't know of a worm that builds tube and eats through coral skeletons, but then again, we probably haven't yet discovered about 70% of marine life.
brown jelly disease is allegedly a bacterial infection caused by stress. as stated, it quickly consumes the coral, and should be vacuumed out asap. some say this can be reversed with an iodine dip. i don't know how true this is, because i have diped corals in the past, that contracted BJD shortly after."

if it's brown jelly on the coral, what is in the tube?

Brown Jelly- Could be it, but, the ?worm-tunnel-thing? Possible be a scavenger attracted to the dying correl? Or did it cause the damage first and the Brown Jelly infection was a secondary result?

Still trying for a ID!!!!
