This came in some rock I picked up from a local tank shutdown. Anyone have any idea what it is?

That's a kind of Polychaete (Bristle Worm) known as a Scale Worm (taxonomic suborder Aphroditiformia), probably Hermenia acantholepis, but I haven't looked into the suborder's families enough to say for certain, and pictures of a lot of these species are hard to come by.

It's most likely predatory toward small inverts like pods, other bristleworms, micro brittle stars, bryozoans, foraminiferans, and possibly things like sponges, small shrimp or other small crustaceans, bivalves, etc. It'll probably also scavenge for food if given the chance.

So, not necessarily harmful in a tank, but not necessarily something you'd want to keep either.
