What is this?

[Brisk]

I saw this inside a small hole in the rock. It's smaller than a dime. I can't tell if it is alive or not. What is this? Is it an urchin?

Looks like a pencil urchin to me.

Pencil urchin. Generally a good guy but can sometimes mow over things and just chew away while it's doing it. Neat find!

I accidentally broke one of it's spine taking it out. Will this cause any harm to it?

If you see it drop it's other spines, it's done for, but otherwise it'll keep on truckin'.

Thank you!

Those things can be crazy... Hopefully it's the Rock Boring type (since it was in a hole in a rock). Mine are half of my Galaxea coral (it was NOT the rock boring type).

Not as bad as my Pincushion... He ate my skimmer cord.

That doesn't sound good. Maybe I should of put it in the sump. I can't find it anymore in the tank. It's smaller than a dime.

Mine was great until it ate the Galaxea. In his defense, he started on the already dead portion and I can't be certain he ate any of the actual live Galaxea heads.

They're cool critters and I'd happily kept mine in my sump after that.
