Pompom crab tank mates?

[Ubans13]

So I have a few fish that have been known to eat inverts by species. In my tank so far have not seen anyone actually swimming with claws or evidence of a killer. So my question is could I add a pompom crab to a tank with a niger trigger, and a Harlequin Tusk. Like I said hermits and all have been ok and snails. I tend to feed pretty heavy.

Not with these fish, the crabs days would be numbered if they didn't eat it immediately.
