Porcelain Crab Annoying BTA?

[TDDredge]

Since my clown 100% ignores my BTA, I picked up a porcelain crab. Had the nem for a month before getting the crab, and it stayed in the spot I put it in for all that time. Not long after I got the crab, with the crab settling right into the nem, the nem moved, and the crab was left behind. After glumly hanging out in a rock crevice for about a week, the crab found the nem again. Cue the nem moving again. And now the crab is with it again. Has anyone else had issues of BTAs moving as a result of porcelain crabs? I'd rather not get rid of the crab, but I'm much more concerned about the BTA going into the overflow or worse a powerhead, or getting on top of some corals if it keeps moving. Considering I have some torches coming next week, I'm rather concerned about the nem moving. Should I be considering removing the crab?

Seriously my nem is burrowing under a rock to escape the crab.

Give the crab something like a piece of shrimp to feed on and divert its attention. If it becomes habitual, place it in sump a few days
