Green Xenia (Clavularia viridis)

This is my second piece of green xenia, the first progressively declined until none of the polyps opened. Anyway, I'm glad to say this new piece is doing much better. Although not brilliant, it has spread to some of the surrounding rocks, but not on the scale I have seen in other reef tanks. It gets good light and strong flow. Another piece of small brown xenia has done much better and in proportion spread further.
