Not many people have this, and it's so much more fun than Acropora turaki. As easy to grow as hawkins and the "dragon" type smooth skins, but with the arborescent habit of the finicky echinatas. The perfectly upright main branches make adult colonies look like a grove of spruce trees, hence the name. Frags are quite large, between 1.5 and 2in with multiple branches, which should allow them to avoid that annoying slow stage that small frags of smooth skin acros go through.
