Bad Urchin?

[Reefer420]

Found another new HH in my tank- a small urchin with a body about the size of a pencil eraser. The spines are light green, are not really all that tightly packed, and are much longer than the body is wide. Sound like a bad guy to have around? He doesn't move much- and has pretty much stayed within a few inches of where I noticed it the other week.

Will try to get pics- right now it is hidden behind some anthelia...

OK- got a decent pic of him..what should I do?

On the same note- what should I do if I see this guy again? (I forget what those flatish snails are called...)

They're bulldozers I tell you!!!! Make sure all rocks are tightly fastened to eachother and no corals are unmounted.

well it hasn't caused any problems since i got the rock (8 months) - its pretty small- less than an inch in diameter if you include the spikes...
