Got a piece of LR with zoanthids the other day and there is something sticking out of it. It is a tube, about 1/2 inch long, about the width of angel hair pasta, the color of the LR. It has two whiskers sticking out of it that are about 1 centimeter long, that look kind of like clear fishing line. They move around, but the tube stays in the same place. Just wondering what it is and if its harmful.
