Don't know what this is - need ID

Hi,

I am getting these white things along the back part of my tank. They look like mini tube worms without the feathers,.. each one are curled up in a circle with mini-hairs protruding out of there sides. The are about 1/8 or 1/16th in size. Any ideas what this might be? is it help for my tank?

 

i think i know what you are talkin about i just started getting them in my tank as well i think they are some sort of tube worm just like a feather duster. but that is just a guess

Im pretty sure i know what you are talking about. They sound like little tube worms, nothing to worry about, just means that tank is doing good

 

probably vermitid snail or Spirorbidae.

 

they are Spirorbid worms and are related to the bristle worm! They are filter feeders and are harmless in a reef tank though they do consume calcium, thus possibly decreasing your calcium level in your water!

 

Thank guys I'll try and get a pic for you, to verify.

This should give you a good illustration of the spirorbid worms!!!!
Are these what you have?

 

CR I think you hit this one on the head of the nail!! Those little things kinda freaked me out when I first got them. I bet every saltwater tank has them!!
