So I have had this zoa in my tank for about 2 or so weeks. Got it as a test coral to see where my tank is at and see if I would be ready for more. However the zoa went square and has stayed this way for a little over a week. Am I doing something wrong? Feed it every other day lights were blue all the time for a while now I have them at 70-80% white and the rest blue. Lights are x2 nicrew 100W (not the sexiest lights but they worked for 2 expensive carpet nems for the previous owner, with other corals too.).
