i wouldn't worry about any id guide, the names are whatever name the vendor gives them. people will say things like that isn't a holy grail because of XY or Z but the reality is if the vendor calls it a holy grail it is, its just a name. people focus too much on the names in euphilia in my opinion, most of them don't keep track of the lineage are a just "IDing" wild corals. so the names don't mean much. If it was more based on the actual lineage i would be much more interested in the names.
