Palythoa on gsp?

[TCseh]

I noticed this growing on a piece of my gsp. The gsp hasn't seemed to extend its polyps for a while so I'm wondering if this is the case. Any idea what it is?

Almost looms like hair algea with a little bubble algea?

I have a few small pieces of bubble algae. Unless it's just my angle the thing I sent a picture of seems flat at the end.

Leaning towards bubble algae based off of first picture. Be cautious getting rid of them if it is infact palys!

Update. I flagged it off. It is some kind of plant or something. It has a stem that goes up to a leaf looking thing.
