Never seen this worm before. Have you? ID please.

It's got a spiral home and seems to be excreting some sort of stringy goo that attaches to the nearby yumas and hammer. Friend or foe?

Sponiod worm.

 

[stovenut]

Never mind. It's called a vermetid snail.

 

[Bongo Shrimp]

Yep, vermetid. Might want to remove/kill it as they can irritate corals with their slime string. A little dab of super glue or epoxy over the top would do it.

Sorry thats what I meant. sponiods are much smaller.
