Spathulata after having it for 6 months seems really undemanding, I have 2 one in a lower section of the tank 20 " down lower flow. The other with really big current, and high light. I would say the one in the high light does better. Neither have ever browned out and look about the same as the day I got it. It is slower growing than a millepora, some call it aussie milli. In 6 months they have only grown 1/2 inch. May just be waiting for to establish then take off. It is a nice coral. The gold/pink one I have glows more than the red/purple.
