Help!!!!!! What is this attached to my zoas???

[muhnandr]

Zoas were bummed for the last couple days so I took a look tonight. Found 3 of these attached to various zoas. They were easy to see as they had a tentacle streaming above them in the flow. What are they and how do I get rid of them? Please help!!! Thanks

I would say a form of flatworm but I can be wrong on this. Please post this as well on the invertebrate forums hopefully LeslieH or other can ID it.

They look like some type of flatworm to me also but I am not sure.

Actually, I think they are ctenophores. Very interesting. Looks like they are not harmful and should not sustain in the tank for long. Thanks
