Worm?

[meera]

pardon my nosy clownfish (who just happens to love cameras).....
can anyone enlighten me on what this tube-like structure protruding from my sandbed is?
ive seen it before but i think my emerald crab mows it down when it gets too high. but this one is untouched and keeps growing. ive never seen anything come out of it.
thanks

Its a feather duster worm. the start of one.

Could also be a spagetti worm...does anything come out of it yet?

I would look into chaetopterid and spionid worms. That tube is pretty consistent with their usual description.

thanks for the suggestions

i haven't seen anything come out of it.
i thought it might be a spaghetti worm, but i'm not sure what to look for.

either way, should I hold a concern for this worm as to whether it is harmful or good to my tank?
