help with worm / disease identifcation

Hi all, first of all i would like to wish everyone has a Happy New Year.
Upon inspecting my tanks and rocks today, i noticed 1 stem of my Candycane
coral is not opening and when i checked behind it, i noticed something was
growning behind it.

the body looks like a white snail body ( with a red flower that opens up at
the end ), it's tiny, about 3 mm in size. I am sure it's one of the common
disease or worm but don't know whether it's harmful, how to treat it or
don't even know what it's called so i don't know what to research on the
internet.

if one of you out there can identify and tell me what it is, i will be very
much appreciated.
i took a picture with my digital camera but doesn't focus well and i am not
sure whether i can post pic in this newsgroup. so if you want to look at
the pic, i can send it to you.

thx in advance for any help.
