TINY YELLOW & BLACK WORMS ?

[SEA ROCK]

IT HAS BEEN A WHILE SINCE I HAVE POSTED ANYTHING BUT HERE GOES SOMETHING..
I HAVE NOTICED YELLOW WORMS WITH BLACK STRIPES AND ABOUT THE WITH OF A LARGE HAIR. THERE ARE CLUSTERS OF THEM THAT I HAD MISTAKENED FOR SOME STRINGY "SEA GARBAGE".
UPON CLOSER INSPECTION I NOTICED THAT THEY DO IN FACT MOVE...NOT ACROSS THE TANK BUT THE SAME LOCALE AND SEEM TO SWAY WITH THE CURRENT.
DOES ANYBODY KNOW WHAT THEASE CREATURES MIGHT BE AND IF THERE ANY GOOD OR IF THEY ARE NOT ??? ANY INFO WILL BE GREATLY APPRECIATED.....THANKS !!

It is real hard to tell in the picture. They are just to slim....about a hairs with maybe 2,3,or 4 inches long & yellow with black stripes.
Anybody else???
