That's a good guy. I can't remember the name but I had one of them for years that came in as a hitch hiker. No worries.

Looks like a pencil urchin.Biggest problem with them is after they get bigger they will move your rocks and corals around.

Rock borer ?
That doesn't sound like a good name lol
Good or bad ?

It's not a pencil. rock borer is what it was called. It's fine. They don't actually chomp your rocks to pieces or anything as far as I have seen. They don't even make caves. Grazing across the reef is all I ever seen the 2 I had do.

They move pretty fast , far as soon as the lights go out

This is a pic of my rock borer.

Shortly after he was put in I did notice that the point of one of my rocks disappeared one night which I attribute to him but *shrug* it might have just crumbled. I haven't really noticed any damage to other rocks since.

Their scientific name is Echinometra if you wanted to look at them in a little more detail.
