What is this? (not an ID question, seriously)

[desx2501]

I bought my first Zoa about 3 weeks back and I notices something "slimy" underneath the piece. I figured it's something related to it's digestive system, but I really have no clues what it is. I took a shot last night of a "tube" that comes out form under the coral. I think the tube is connected to the slimy thing. Is this normal on a Zoa, or is it something completely unrelated? (There is more than one such tube btw)

It is an ID question - that's a sea squirt.

Oh, ok thanks. I though it was a part of the Zoa, hence why I said it wasn't about IDing the Zoa.

I'll read about "sea squirt" then.

Thanks again!

Is that like a money shot?
