Better Pic of Unknown ID

[jumpfrog]

I posted a pic last week of this clear tube that continues to grow.
The picture last week wasn't too clear so I'm trying again.
Anyone have any idea what this thing is?

Any thoughts or guesses would be helpful.
TIA

Still looks like a hard shell feather worm tube to me. If you can not find anything coming out of it, it is just a feather worm tube that the worm has left after dying. I have a couple just like it.

Wash your hands, rinse them off thoroughly. Put your hand in there and touch it. Is it hard, or is it soft to the touch?
Hi Sammy!

Eww, I touched it!
Just kidden' thanks for taking the interest steamboat.
ok, the pink area around it is soft, kind of spongy feeling. The
clear tube itself is soft almost like jelly. It didn't retract and it's not calcerous like the tube of a worm.
In a way it's almost like a tunicate but I notice that the tube is getting longer.
I've never seen anything come out of it.
Any thoughts

I agree with the sponge ID.

A Tunicate...

Positive its a SEA SQUIRT!

I agree I think it is also a sea squirt

its a tunicate it is a sign of high quality rock,but their is a chance of sea squirt.

I love this place!
Thanks everyone for your input.
I guess it's either a sea squirt or a tunicate.
Will this get bigger, anything special I should do?
The more I learn about this hobby the easier the fish and corals seem to be. It's all the other stuff that's difficult to understand/ID.

I have some of those on my LR. For me it looks like sponges. But as i know you cannot expose the sponge to air. I was pulling out my LR couple of month ago, but now this "thing" is growing again.
