What on earth happened to it?

Oh heck no. Griff has eaten many a things but has no interest what so ever in the nem. The maroon clownfish that was hosting it would launch such a vicious attack on whatever swam anywhere near the nem, nobody dared to go over there. The damage on the nem was below the rock line it was nestled in. No fish could get below the tenticles if it wanted to do so.

The best I can describe these injuries to the nem is the outside looked like an exit wound from a bullet. I was able to put my finger inside of it, but did not really go in to check it out. I'm not the type of person to be sticking my finger in strange holes. Perhaps I should have done so to see if something might have been inside. There was no change in water quality at all and I checked before bed and after wake up. This was a very sudden thing to happen.

Were they eating it? I have yet to be able to keep a nem with puffers. They have eaten them every time
