The Green Hydnophora is an LPS coral (Large polyp stony) which looks surprising similar to an SPS coral at first glance.  

Therefore they are a great addition for anyone trying to get that branching SPS look without the same car requirements.  

This coral needs appropriate 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 sea water.

Additional feeding isn't required to maintain its health however it will feed on micro-plankton and very fine coral foods.
