Recently I noticed some white/soft stuff on the back(dark) side of a
bottom rock, I originally thought it is some sort of sponge. But it start
to become bigger and develop some sort of long head, and there are
some similar white stuff on one of the LPS. I am getting worried, here
are some pictures, anybody have idea what it is and should I be
concern about it?
