I dont think that is a coral. There are 3 different shades of corals from 3 different companies. At one time Les Jones had a pic of the 3 and from which company. Contrary to Galen and others, I think this is a CAC. The base is clear though with green filiaments inside making it appear green.
in this pic second vertcal row, second one down is an example that I think Kevin has.
