Large(r) tube-building worm ID

[MrMreef]

Hey everyone - spotted this beauty at the base of an Alveopora; it’s around 3-5 cm (1-2”) long and the tube diameter is about 0.5 ish cm (1/8”).

The tube is quite ornate with visible segmentation. There’s no visible comb and has a trapdoor and retracts when exposed to light.

What could it be? It looks a bit big for a chaetopterid or Spirorbid worm…

It looks like a spirorbid worm to me.

Literally have one of these exact worms. Did you ever figure out what it was?

It’s definitely some sort of vermetid worm (the little spirorbids always have a feather or fan, these guys don’t) - the population spread a little and started to really annoy my Alveopora… So I superglued them shut

Here’s a new pic of one just under the left head of this frogspawn (end-on)
