good or bad

these little white tubes have two tiny long tenicals. i acully seen one tht had a baby shrimp wraped up. does any one have a clue what they are?

 

i alve a bunch of feather dusters growing on my glass at least i think there feather dusters i hope they are cause it would be cool to have them grow allover the walls. but will problly make scrappng coraline a pain in the butt. i will try to get a pic also.

 

might be a vermented snail. pic not very clear though.

 

they are the white tubes that are under the purple rock the look a lot like a feather duster tube but instead there is only two tenecals that come out.

 

Probably either a Spionid or Terrebellidae worm, harmless scavengers of left over food and other detritus.
