I can verify that Les posted that picture with those IDs but it was a long time ago. Not long before this, collectors called all corals CA for many years. Les changed the entire hobby with this picture and ID in an Ebay auction. At least that's when it changed for me.
Les went on to get heavily involved in the CA digs after this. I could be wrong but I think he changed his mind about the whole coral situation. The current feeling, far as I know, is that all corals were Champion.
It doesn't seem right to me somehow, to just group the clear green base killer corals with all the rest though. All the corals are attractive, but I really love the clear green ones.
