    1. is where is started. I thought it was one of my fish nibbling at the growth tips. Did some late night inspections for some sort of crab action. Nothing.

    2. this seems like some sort of tunnel. It's almost like a 'worm' is 'eating' the skeleton and leaving this hollowed out tunnel.

    Has any one seen or experienced this before?
    I had to cut this piece off and I'm hoping that it doesn't spread.

    Keep an eye on it after lights out to spot the culprit

    I had the exactly the same thing, first started eating my acro, then when that died it started on my monti, it literally eats away at the skeleton, not just the polyps, my acro had pieces missing.

    It looks just like a flat bristle worm! only comes out at night.

    It would hide deep in the rock and only come out to feed. I tried every thing to kill it, I even putting Loguls and kalkwasser down the holes in the rock, nothing killed it, I had to remove the rock and place in RO water for 24hrs before it died.

    I've just engaged in the unpleasant task of pulling the piece of liverock out (naturally it would be the piece right at the bottom of the stack), removed corals and placed in RO water. There's already a couple of worms lying on the bottom of the container.
    I really hope this will get this coral eating fiend. I just hope it didn't multiply and spread through the whole tank.
