SPS ID

[Roc]

I think this is some type of Acro, but I have never seen one that looked like this. It started as a 1/2" about 4-5 months ago and was about .5 " around, it was a single branch.

Now it is about 3" tall and almost 2" at it's widest point (the base) it has completely encrusted the frag plug it came on.

Any ideas about a common name or actual name other then "some type of Acro"

(this pic is under my T5's)

It's a bit small for IDing....Get the polyps to retract and take another so we can see the base

The polyps never seem to retract....................

All polyps will retract if you slightly brush your finger over them

Ok Gresh I will try that but this thing never seems to retract....................

touch it with your finger or blow some water on it, that should get the polyps to retract

Ok I blew on this thing for 5 mins and finally it closed up.

I'm going to go with the "it's too small to tell" answer. While you can see the coralite structure as nice round little balls, figuring out how those branches with grow is also useful in identification.

IMO what you got there is Acropora sp. until I can see how that frag grows out

If you want something more than that I'd say Acropora loripes with about a 5% certainty
