Leather Worm ID
I have a bunch (3-4) of these tubes growing around the base of my Finger leather. I'm assuming they harmless since the coral shows no Ill effects and just keeps growing. What type of creatures are these?

Spionids or chaetopterids is my guess as well. In any event, my guess is that you don't have anything to worry about.

The largest one is about 3" long and they are about 1/8th to 1/4" in diameter maybe

Then those are not spionids or chaetopterids. These are small/tiny worms, so it is either a serpulid or sabellid tube worm. It may be they have not stuck their head out all the way. Looking at that tube now, with dimensions in play, it looks like a sabellid.

I'll have to try to watch them closer the tube in the 2nd pic I've never seen anything emerge the other one in the 1st pic looks like the spinoid worm but where it's positioned in the tank it's really hard to get a good pic

It's a chaetopterid tube. You can tell by the structure - if it looks like a translucent drinking straw and especially if it has transverse rings it's a chaetopterid. That plus the 2 feeding appendages confirms it. Some chaetopterids get quite large so size isn't an issue here.

No 
They are not chaetopterids either. Although some get large, not these with this kind of tube. It is te '"U" tube type that get large, where the worm is in the buried in the sand.
You can not go by Kelly's image. That could be the head of a feather duster, that has lost the top sticking out or just part of the duster top. You also can not tell the difference really between a chaetopterid and a Spionid unless it is sittng in from of your face on a lab bench, under a scope. I think Leslie is looking at my pic and not the one at the top of this post. And my pic is a properly ID Spionid and not a Chaetopterid. However, chaetopterid tubes of this type, can get up to about two inches maybe and she is at three inches. Her pic is about a 3 " tube and to big in dia.
Finally, these worms grow in the sand and mud and hers is attached to a coral. They do not live that way. I should have said that right off. Got excited I guess
