Deep water Acroporas can be awesome specimens for the captive reef aquarium.  They have very delicate branching which gives these corals a unique and interesting appearance.  The coral pictured above came from the great barrier reef as a wild colony, but most of the original mass developed necrosis and perished in the first few months in captivity.  Several small growth tips were fragmented from the original colony and managed to acclimate to conditions. One of these grew into this colony we see today.  These deep water acroporas can be some of the most sensitive stony corals to keep and grow in captivity, as they prefer lower light conditions and high plankton density.   They can develop some beautiful structure and pigments if they survive long term, and once a specimen has acclimated to artificial conditions it fares very well and can be rather hardy.  This particular specimen is finally growing well and adding new mass quite quickly, but it took about 2 years for it to gain a good foot hold.  I believe this coral is a Acropora Cardus and can be found in deeper water, reef backs, and lagoons in the wild.  Most are cream or brown when collected, but once they have become fully acclimated to artificial light and conditions, develop some very nice pigments.
