Tiny red fans?

[Be102]

Any clue what these things are? There are two of them on my Duncan coral. Any ideas? Should I dip it?

Tube worm. Nothing to worry about.

They look like vermitid snails to me that are the actual coral Do they send out a web? They can be irritating to the coral and you can snap them off and cover the hole with super glue. They are feather dusters (tube worms) on the plug.

The red ones are feather dusters.
