Yeah, mine don't throw out a mucus net.
I do have some spinoid worms as well. They have little sand encrusted tubes and have 2 thin tentacles that come out.
I originally thought the hydroids were the same thing as the spinoid worms with the little tubes. Except they only had the one tentacle. They are so thin, maybe just a tad thicker than a stand of hair. So I didn't even notice at first that they were different, other than they come out of holes in the rocks. So I looked at them up close and they look exactly like this: http://www.mikesreef.com/images/crit...tchhiker17.jpg
Ill try and get video and pics. Funny thing is, they haven't come out in two days which is unusual. So either the new cleaner shrimp is eating them, or the just arent hungry and are only coming out at night now. Ill keep you updated.
