Friend or Foe?

This little guy surprised me when I was doing a routine rock cleaning. About 15 mm in length. Any idea what it would be grazing on, such as my corals? I don't want to kill it, but ... please help.

Probably a scutus. They're harmless.

Friend or Foe?

Thanks for the reply. It was the "pinchers" that got my attention.

He's a friend, as Adrienne says. But he's a black Stomatella. Here's his shell (pardon the art work):

Thanks! I'll get him back into the primary tank.
