    Found this in my DT recently. Showed up out of nowhere. Any idea what it is?

    Are you asking about the pencil urchin?

    Ask and you may find out, don't ask and you will never know.

    Naw not a pencil, its what is usually called a rock boring urchin, genus Echinometra, much more reef safe than pencil urchins

    But they will eat right into live rock and can scratch acrylic.

    Nice, luckily I have a glass tank heh. Not too worried about the rock.

    Thanks everyone!

    Got a small piece of gulf cultured rock a few months ago. Guess there was an egg on it that finally hatched.
