no green .. pale brown, beige looking .. they're very short & look like a closed polyp .. google images for tube worms didnt turn up anything similar, but i dont doubt you guys.
they dont move though, do tubeworms? and are they negative at all?
i tried ripping them out and it was almost impossible (but they're small & i have fat fingers so it wasnt ideal) and a toothbrush did nothing.
its a great piece of building rock, but i think i might just boot it .. or break it and use where they arent
THANKS FOR THE HELP!!!!! i really appreciate it
