Also read a scientific research article that the worm itself, its action going in and out also causes tissue damage to coral around its tube.

Thanks! Yea read those links and video. ID as Morgan's coral hermit crab. mentioning filter feeder and meaty food nearby. But however no mention if coral safe. Anyway already in tank and shall see how it goes. You know how to lure and catch the crab?

Looks exactly like below. https://reefguide.org/pagurittasp1.html

Hi there, Recently bought a christmas worm rock and found hitchhikers - coral hermit crabs. Several of them in empty cavities. Are these hermit crabs reef safe? I could not find much info on these. Other name found is Paguritta sp. Can anyone advise? Thanks.
