Need ID on this

[Goodgreef]

My best guess is it's some kind of cup coral. Help appreciated. It is a cadmium/mint color.

 

[Oscaror]

goniopora

 

[Tab28]

It is a bit small. Does it have any type of polyps that come out or does it remain looking more like that.

 

[Goodgreef]

It pretty much looks like that. The round heads extend out a tiny bit more on occassion. The heads dont have tentacles/frills on them like a goniopora does.

 

[Tab28]

Could it be a cyphastrea

 

[Goodgreef]

Possibly. That's a good idea. Maybe the polyps will extend more and it will become clearer what it is. I've only had it for 3 days.

 

[Goodgreef]

Here it is now. Polyps are extended more. Any thoughts?

 

[Tab28]

Now it looks like it could be goniopora as Oscaror suggested. It may in a day or so the tentacles may appear. It is an encrusting type, which are more hardy
