This is one of the fastest growing and hardiest of all corals. It’s also undoubtedly the brightest fluorescent green of any coral. Some love it for its bright color and motion as it sways in the current. Some hate it because it grows fast, and can take over a tank if not controlled.
This variety grows first by encrusting then by branching. This coral will thrive in a wide variety of conditions, but does best with moderate to high light and flow, and plenty of nutrients.
The frag you purchase will come from the same lineage as the image shown, and will have a similar number of polyps, but because of natural variation among frags yours may not look identical to this image.
