I have several Acros that I have no clue about. Can anyone tell what these are? I know the pictures are terrible. This one is about 3-4 tall and is green with some blue at the tips near the polyps. This one is about 4" and the color is mostly bluish-purple. This one is about 1 1/2". It is medium green with deep red almost brown polyps. Not sure of the growth pattern of this one.
