These are 2 head rock mounted pieces of TR Metallic Green and Purple Tip Branching Hammer LPS Coral. Each head expands approx 2 inches
Being an LPS it's preferred area is on the sand bed or up as high as 1/3 up into the tank.
Lower water flow will help it expand into it's full beauty.
Direct feeding is not necessary.
Picture here is under full day light lighting. More actinic blue will pop the colors.
