Whiskers on Hammer Coral Branch

[Krilla]

Can someone help me identify what these whiskers are? I've seen them before in a pair but never this many. What is this Hammer's branch infested with and do I need to take action before it spreads?

I’m guessing vermitid snails— we’ll see what others think

prob spionid worms.
