Light your tank on fire and shoot a gun into the flames! Joking aside those things really creep me out! I've never heard of a predator for them unfortunately.
There probably are predators in the wild. Whether the predator would be an acceptable alternative to the worm is another issue.Why aren't they taking over the reefs in nature then, with their sheer size, appetite and lack of predation

Sorry...
Back to the question:
I think, and these are my thoughts, that their predator would be a fish that eats invertebrates, as in not reef safe. Bilk listed some possible candidates, I would add the large angels and wrasses that pick at the rocks for invertebrates as they should be able to grab a worm.
But who will be the one to put a non reef safe fish in their aquarium to see if they will eat the bobbit worm.
