That don't look like a zoa...

[Kehy]

Just noticed it today, guessing a coral of some type, but honestly I don't have a clue. I just noticed it today, but I've been watching the tank pretty frequently and didn't see it before. The frag was added... 2 weeks ago?

I have no idea what 'thing' it is you are asking about? It might help if you added a arrow pointing at it or draw a circle around it.

Look at the first pic to the right of the middle zoa, maybe its that green thing he's asking about?

 

[New&no clue]

Does it open up?

 

[Kehy]

Yup, it's the green thing. Wasn't able to see if it opens up more, that's as open as I saw it yesterday

 

[New&no clue]

in the last picture if you zoom in it looks like little clear tentacles are coming out, almost like feeder tentacles.

 

[Kehy]

When it retracts, it just looks like a flat green splotch

If you look right next to that button, you can see the remnants of a stony. I wonder if it's from that?

I saw the same thing but when I zoomed in, it looks like the tentacles are coming out of the rock.

candy cane coral

I think you may be right. It looks like it's growing on an old candy cane coral skeleton.

Not candy cane, that's a branching coral. Most likely a Micro Lord, I have owned some with the same coloration (which is not at all like that of a candy cane). Either way, awesome find my friend! Whatever it is, keep it fed and it should have new growth!
Good luck, stay safe and God bless you!
