It tolerates slightly elevated nutrient levels but prefers nitrates <20 ppm. Calcium and magnesium should be kept within marine norms. It can be fed liquid phytoplankton. Beware of its rapid growth: it can overgrow other corals. Trim regularly to contain it. It propagates by fragmentation or by detaching fragments.
