The base area and shaded areas of this coral develops a forest green fluorescent pigment. Polyps also tend to have this green. While in upper areas and areas that receive brighter light, a bright fluorescent orange pigment occurs that can even be seen in polyps. So basically you have a two faced or two color acro. Low light green and bright light orange. In addition to this the branch ends develop pink or purplish pigments that can occur on the branch stems and are very bright on corallite walls and edges. Polyps in these pink areas are mostly orange colored, but some can also retain the green pigment. It should also be noted that some polyp tentacles possess a dark colored tip. Joe has developed these qualities under strong lighting and strong water current.
