I have these reddish brown hard poky things on my live rock, they are tubular in shape and appear to have a opening on the end. I have never seen them move, retract or anything come out of them. I would like to know if they are ok in the tank or if I need to try to get rid of them some how. They are stuck to the rocks pretty good. I am pretty new to all this but from pics I have seen I am leaning towards identifying them as Vermetids
Any input much appreciated.
