Anyone know what coral this is?

[Deux ex Machina]

I have a relatively new tank (4 months old). I found this patch of coral on a piece of live rock. At first I thought it was just a skeleton of a dead coral, but on close inspection you can see the tentacles moving on the polyps. The polyps are maybe 1 mm in diameter.

It looks like some Leptastrea.sp

Could you get a pic with the polyps retracted?

[Deux ex Machina]

I've never seen it with the polyps retracted. I suppose I could force it to retract it's polyps. What are you looking for?

[Myka]

I would like to see the skeleton, and how the corallites are formed.
