Can Anyone Identify This Hitch Hiker

[CDone]

Noticed this creature on my rock, unfortunately its in an awkward spot to get a good photo of. It has shiny glassy hairs (spikes) radiating out from a center, I've also noticed tentacles sweeping out from it once in a while.

Here's a really poor photo, but you can see the hairs, spikes reflecting light.

Thanks
Colin

Maybe an apitasia or a feather duster.

Closest I can find is the Strawberry Worm (Eupolymnia Nebulosa)

But my rock is from Jakarta/Indonesia and these worms originate in the North Sea. Do other bristle worms have the long spines and tentacles seen here?

Thanks guys, looks like I'm gonna pull that piece of rock anyways as a small forest of Red Hydroids has sprung up in the last 2 days, I'll try to reposition the rock so I can get a clearer view of whats in it.

I have a number of those in my tank. one under a brain, and a few here and there. the rainbow colored hairs are very cool(if hard to see) but in the two or three years they've been there, there has been no ill side effects i can attribute to them. sorry i cant tell the name because i have yet to find a good ID for them myself.

Do barnacles have tentacles? Honestly I've seen plenty of barnacles along the west coast of Vancouver Island, and this doesn't look like one, it seems to have a hole in the rock with these glassy hairs radiating out from it and then a couple tentacles that sweep out every so often. Once in a while it pokes its head out and it seems to be red in color.

I've turned the piece of rock to get a better view so I will try to post a couple more pics tonight.

Thanks
Colin

Heres a couple clearer shots, note the tentacles.

please disregard the Hydroid forest, they will soon be removed.

Mine backs in and out from its hole in the rock, leaving a nice circular opening, wish I could get a really good photo of it.

Definitely a barnacle.

Definitely not. It's a polychaete in the family Flabelligeridae. What you're seeing is the cephalic cage, a group of bristles near the head. Colin - those 2 "tentacles" you saw are the palps, feeding structures that string a web of mucus over the bristles & later remove the particles that get caught on the web. Some good pictures have been posted on RC. Do a search for flabelligerid, Pherusa or Piromis and you should be able to find them.

To barnacle or not to barnacle? That is the question.
