The Dark Green Millepora is an SPS coral (small polyp stony) and coral needs good lighting and moderate flow to maintain optimum health.

In addition to this, it will also require the correct levels of Calcium, Alkalinity, and Magnesium along with various other trace elements found in natural seawater.

Additional feeding isn't required to maintain its health, as they get the majority of their food from photosynthesis. However, they will feed on micro-plankton and very fine coral foods.

Be sure to keep an eye on your nutrient levels though, as excessive nutrients can cause it to lose colouration.
