Pest Worm

[Sticker shock]

This is the second of these worms that I have found in my tank. Both came in on a zoa frag and survuved multiple dips in Bayer and Peroxide. I know this pic is crappy, but can anyone identify this? The worm is on the top frag plug and slightly below the center. Its kind of white/off white and is spikey like a bristleworm but much less bristels. I wish I had a macro lense to get a better shot of this.

It pretty much casts itself out in the current, but I can see it moving in and out. It must be in some sort of tube as it is always in the same place.
The first one I just covered with super glue and planned to do the same here, but wanted to see if anyone knew what I was looking at. It certainly has been giving these zoas a hard time.

Hard to tell from the pic.

I know it is. Whatever it was, is now cover in super glue gel...never to be heard from again. It was about the size of a vermetid, but without the hard shell. On top of that it sort of looked like a polycheate worm...however it never hid or went to a different location. It would just extend and get blown around in the current. Both zoa colonies were certainly effected by them.

What you are describing sounds like a digitate hydroid. A polychaete isn't just gonna sit there and let you glue it unless it's drunk or something

Absolutely what it was. Good call.
