The term tricolor was coined by SDC and generally refers to an Acropora that has bright green polyps (color 1), purple tips or purple branches (color 2) and a brown base and or brown lower branch area (color 3). There have been quite a few tricolor species imported from Fiji over the past few years. These generally are thicker branched Acropora that have tended to be very difficult to maintain coloration in captivity. Photo and text courtesy of Reeffarmers.
