My Trigger is gone????

Both Nems are BTA's he was really too big for them to eat without some leftovers.
The tank is not that old so there are not that many worms right now.
No mantis or other crabs as all rock has been with me for some time, and i only have about 10 small blue legs so I don't really think they would have finished him off that fast. I still think he jumped that or my cat likes fishing.
