I just bought a sand sifting starfish and the minute a put it in the tank my peppermint shrimp came and picked him from the sand. I scared him away from the starfish and it is fine.
Maybe he was checking out the new addition. Unfortunately, sand sifting stars need a rather large and very mature tank. They tend to exhaust their food supply rather quickly and end up starving.

I've got two or three peps in my tank and I couldn't see them taking on anything as big as as sand-sifting starfish. Some of the little asterinas on the glass....maybe, but they can't be bothered.
My tank is 65 gal. has only been running for 2 months. Perhaps I have thrown the starfish in there prematurely. I will make sure that some supplemental food hits the sand for him to eat. How big do you think it will get in the tank I have?
