Hard to tell from pic. Christmas tree worm??

 

[infimurf]

Hard to get a clear pic. It's at the back of the refugium. It lives in a round shell like structure with a point on the front of it. There is also a larger shell 1" with the same point but no inhabitant

Spirobranchus giganteus, harmless. Feeds on suspended particles in the water column.

 

[infimurf]

reading on Spirobranchus giganteus it says it has twin spirals. This has three and is more bottle brush shaped.

 

[Tahoe61]

Probably just a close cousin.

Look around
