A week later I came home and the dog had a 6 month old calf by the neck trying to take it down. The dog didnt do it because he was hungry and I dont even think he did it from instinct. I think he was bored and it was something to "play" with. The calf was fine, the dog didnt fare so well.

Im wondering if your puffer didnt get bored and started poking or bumping the nem? And as it goo'd the more fun it became?

Exactly what I was getting at. I came home one day years ago to my dogface ripping EVERY soft coral in my tank apart just for the heck of it! Not eating them, just destroying the reef. And he had lived a long, long time with all the corals and never so much as nipped them until then...LOL...puffers are sooooo weird.
