What is this????

I found this weird thing in my tank, it opens and closes like a scallop or clam and has what looks like two worms in it. It’s hard to get a picture of the “worms” but they look like they have black and white rings.

Following… i have no clue, but there’s some scary looking critters that come in on live rock and corals that ends up growing pretty big in our tanks.

It’s definitely weird and blends in perfectly with the rock.

Looks like some sort of Bivalve clam, generally fairly reef safe.
