Anemone? Coral? What is this?

[dbati]

I noticed this brown coral looking thing on one of my live rock the day after the dust settled when I first set up the tank. A couple of months have passed and it has not shrunk or grown.

Can anyone help identify what it may be?

Does it move?
Pics fuzzy but looks like cyphastrea or similar coral

It’s been in the same spot since I noticed it. So it’s probably a coral. Pretty resilient if that’s the case, no?

Yes and i too thought coral but has the appearance of a nudibranch at first glance

Where is the rock from? If it is from Florida, it looks like some form of encrusting Porites or brain coral, perhaps Porites astreoides or even Dendrogyra cylindrus.

Yup. I’m in Miami and I got my LR at an LFS

I don’t think it’s either of those corals. After looking them up the polyps don’t seem to match.

Maybe the Montastraea cavernosa

Some kind of montipora do you have any pics under blue lights?

I don’t have the proper lighting. Which is why I only have a couple soft corals in the tank right now.

Again, the polyps look a bit different. He’s a zoomed albeit blurry pic. You may be able to get a better sense for the polyps in this one.

 

[Anemone_Fanatic]

Yeah, looking at the polyps up close it doesn't appear to be either. I'm looking forward to seeing what it will grow into.

montisraea, rose/flower coral ??

 

[vetteguy53081]

May also be galaxia coral

Where’d the rock come from? Did it come from another tank? I went with monti because the polyps look like they are coming out of a skeletal structure.

Just out of a bin at the fish store I went to. I’m assuming they’re FL live rock since I’m in FL.

If they are from Florida, then it is probably not a cyphastrea. It is probably some atlantic stony coral. Looks to me like a porites, but I could be wrong,

Update: looks like the polyps are a bit more extended. And they seem to be enjoying the better lighting and increased flow. I’m leaning towards it being an SPS coral if someone type.
