I was gone this afternoon and when I came back. well, he was gone. There is a lot of fin pointing going on right now between the triggers & the puffer. But, I think it was the puffer. Even though I have several large hermits in there. Puff daddy had a thing for the monster. He would lay right down on him. and never let him get to far away. I guess he just couldn't take it anymore and ate him. I've found several parts lying around the tank. Like a big pincher.
