worm id good or bad

[swnoob]

Found these in some live rock i was given. The rock also has some aiptasia. Was thinking of adding some berghia nudibranch for the aiptasia but worried the worms may get to them first.

The biggest worm is about 4" in length.

Sorry, that's a nemertean AKA ribbon worm. It's a predator but on things like smaller worms and crustaceans.
