What is this acro?

It's all purple like the right side of it, it just looks like its brown for some reason.

 

A. valida?

 

Yup, looks like one to be as well. Cream color body with blue/purple tips. Some times the polyps are greenish in color.

 

Ok thanks now I have another one for you guys. I know the picture is crappy but it is the best I can do right now. But the stony part is like a bone color and the polyps are brown. It is not dying or in healthy that is just the color of it.

 

No one?

 

Gonna need the last one to grow some before we can tell. Might be a prostrata or millepora but too difficult to tell for any certainty.

 

Need a different angle and as John posted some growth, really hard to tell on some frags.
