Tough Id

I Know this is hard to do.. Trust me I've tried for a while. I have an Acro that I've had wars with, from stn, to bleached tips. It's doing great now and is growing really fast. Bottom line, I'd like to find out the species that this thing is. Sometimes I think tort and other times I think the one branch looks a lot like a milli, but the polyps are way too short and are a completely different shape... Here it is.

Btw, the one pic has a blasto merletti, that's not the one I'm looking for.

 

It's hard to tell from the angel. It's not a tortuosa and not a millepora. My best guess for now is Acropora chesterfieldensis.

 

I'm thinking I'm going to need to wait about a half a year for some more growth, it will probably be easier then. The link you posted was pretty accurate though, mines a little less rounded, but that might just be the way it is in my tank.
