Any Idea What This Might Be?

[EzraZamir]

Hi Everyone!
I've had these zoas for a couple years and they started melting after a small purple/red polyp started appearing a few months ago. I now have this big transparent purple/red polyp with what appears to be a mouth, plus 3 others growing behind it. Any idea what could have attached itself? I've been reefing for about 3 years and have never seen something like this yet, and have had no luck searching Google.

It looks like an algae has taken root there. Red valonia or maybe something else.

I thought that until I saw the mouth...that totally threw me! Maybe that white line isn’t a mouth?

That was my first guess until that white line started which looks like a mouth.

Pics unfortunately aren't quite clear enough for me to tell.

It does look like Red Bubble algae.
