I have had these green buttons for so long I actually cant remember when I got them. I believe it was in 1998 shortly after the heater mishap. These too were nearly decimated by the Aiptasia infestation. At one point in time there was only about 5 or 6 polyps left. This picture once again does not do justice, for they are a metallic green color,Actinics REALLY show them off.
