Hey Jun, long time!
The blue ridge is still happy and growing. After a couple of vacation trips where the low water level exposed the tips, and the skeleton started growing algae, it has now almost completely covered those areas, maybe 1/4" left. And the "skin" has completely covered the rock it's growing on, down to where it would get no light. In the back it's made a truce with some clove polyps....neither advances, neither recedes. On the side it has completely grown around the stalks of some xenias....I've finally found a way to keep xenia from spreading!
