Ahhh I see you believe in research first buy later....just kidding but it is always good to research the wants and needs of additions prior to getting them. This is a cat's paw or stylophora and a very nice one I may add. Congrats.
"It is a moderately difficult coral to maintain in the reef aquarium and should only be incorporated into a mature reef aquarium. To bring out its brightest colors, the Stylophora Coral needs strong lighting provided by preferably metal halides"
i dont have metal halides but i have it way up on top by the light and its doing great in my tank right now. kay bee the green variety is really awsome looking cant wait to get my hands on that color...
