We have Nuclear Green Zoanthids here
and we have them under T5 lighting. Not sure if you are talking about the same zoas but I thought I would bring it up just in case
Zoas in General can be kept under many different lighting all the way from PC to MH. I have noticed that depending on the color morphs, some does better under regular T5/PC then MH. At times, Zoas tend to shift in color, hence too much or little light .
flow,,,is the main thing,,,moderate indirect flow..and they will be happy. as said light is a factor in them too,,,to much and orange/red go brown,,,not enough,,,blues go pale...but as they spred,,,they will find their happy place.
