2 ID's please w/ photos, Bristle worm?

Both of these hitchhikers are on the same rock! Along with some apashia. The rock is very easy to remove from the tank if these things need to be taken out.. The 1st is the zig-zag looking think under the mushroom. I think it may be a feather duster? It hides when something comes near it...
The 2nd is the worm thing. I checked out a website that was reccomended on here to identify another type of worm and I think it may be a bristle worm OR (probably this one) Lumbrinerids.. It has the mouth like thing that goes after food. It stays in this rock and ONLY comes out when food is around. Is this a bad worm? Thanks for your help!

You're safe. It's just a bristleworm and a feather duster like you thought.

i would keep the bristle worms because they aet leftover food and rotting meat, wich keeps nitrates down.

Not sure this even matters, but those tweezers your using look like they are rusting. Doesn't rust hurt things in a tank since its metal?

Yup they are rusty but I dont Keep them in the tank so they dont bother things. they rust cuz the salt water.. cant stop it
