Some urchin, I'd say

 

[jeffmuse]

I am pretty sure that it is a feather duster/ fan worm.... if you are going to get a hitch hiker, then this is a pretty good one to get

Here is some general information on them... see if the pics on the site match what you are seeing in your tank:

Looks cool! I say urchin

 

[schwaggs]

Does it move or is it always in the same place? Are the spines solid or do they bend?

If it moves, urchin. If the spines are flexible or the animal never moves, feather duster.

Spines appear to random not shaped like a duster.

From the way that the spines look like they extend radially from a central point, I'm going to guess that it's an urchin of some kind too.

Edit: Unless there are clearer pictures I will have to agree with Robb.

Does not look like a duster at all. I have a few that pop out of holes and a few that grew the white tubes outside of the rock. they all look like 'cones' per say. With all of the appendages coming out of one central spot. One quick test you can do:
Grab a small straw and move it near this creature. A feather duster will suck itself back into the hole or tube as you get near it.

btw.. the safest way to test on things is with a straw or something else. If it was a urchin and you had your fingers in there, you could be in for a long night of pain.

Also known as a Double Spined Sea Urchin (Echinothrix calamaris)

Looks like they are capable of some very painful stings!

they're reef safe, but they'll eat every square millimeter of Coralline that's in your tank...

+1.. hehehe i'm sure you just made his day Always something bad with the good.

tbettis,
Img 006 - VERY nice tank you have. How old and big is it? Odd question... assuming your going to get the urchin out one day, how the heck are you going to get your arm in that tank?
At the very least he will get pretty big with all the rock/Coralline you have in the tank.

I spray painted my white PVC overflow black....... My urchin ate the black spray paint! Left white streaks all over it until it was white again.....
