URGENT! Please ID this invert in Reef tank

[allboutthe305]

Decided to put my iPhone flashlight to my reef tank just to check a coral and found something I've never seen before. This thing has MASSIVE tentacles reaching half way across a 55g tank.

Any idea what this creature is? The good and bad?
Had semi-clear tentacles with very few white spots.
Will it hurts my corals? Zoa's, Paly's, LPS and SPS

Possible Spionid Worm.

This thing has at least 5 tentacles. And I found a second one about 8 inches away from that one with at least 3 tentacles.

Actually I think your right. Looking at several pictures that might be it.

Will they harm my Zoa's I've read yes and no. But this thing is on my main base rock that has several little frag rocks glued to it. How can I remove it if it is harmful?

You could start with a dollop of super glue gel to cover the opening of it's tube. This may force it to create an opening elsewhere. It's been my experience that they are harmless.

Great read on worms and feeding habits.

That's the problem, it's on my main rock on the backside against the glass. So I can't actually see the base only the tentacles at night.

Then I wouldn't worry about it at all. They feed by filtering food from the water. Just leave it be [emoji2]

I'm taking your advice. Let's see what happens.
