Need to ID a couple critters

[beyer]

This is in between two branching frogspawn heads. Dark purple/brownish in color. Also looks like a similar things on the right of the pic.


This is the bottom part of the branching frogspawn and in the center of the pic (excuse the poor photo) is a worm or something similar that pokes its head out every now and then and when I get close to it in the tank it quickly hides back in the branch. Can anyone ID these critters?

Also have what I think is a few feather dusters (bottom of pic #2) in the tank towards the bottom of some of my frags but I've heard they are harmless in the reef tank.

Any help IDing these would be great!

Vermetid Snail.

Yes looks like a feather duster.

Both the first and second pic are both vermetid snails? So add glue to kill them off?

Honestly I'm not sure what you are referring to in the second picture. Granted tossing some super glue gel over the opening would kill it, just like the vermetid.
