Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I'd definitely say Vermetid Snails....I have them as well. They reproduce a lot if they have food...but they will die off as well. But the tubes will always stay.
I've been trying to find a solution to them as well. I have not yet found a predator of them. Short of snapping them off one by one, they really will never go away.
Try this for a ID. http://www.xtalworld.com/Aquarium/hitchfaq.htm
They are ether micro FEATHER DUSTERS, SPIONID WORMS or VERMITID SNAILS.
All are harmless and show that you have diversity in your tank, cutting yourself, bad, could lead to reef rash, trust me, wear gloves from now on!

yeah I will have to look at the id when I go home as my work blocks that site. Trust me a few times i got like a scratch puncture from them and they hurt like hell.
