well i wish i could put a picture on here but its too small and the picture got too blurry. anyway i was looking at my tank today and noticed something attached to the live rock. it looks like its a little caccoon and has these tiny tenticles coming out of it..at first i just thought it was some kind of algae but whenever a fish swims by the tenticles retract and then come back out. any ideas? i know a pic would be helpful and as soon as i can take one where you can actually see what it is ill post it...thanks

Does it look like a straight or spiral tube? Describe the cocoon a little better.
Heck, draw a picture if you can.
