I have Zoanthus Colony Polyps that I purchased just over a week ago. I can't figure out what they are doing. My light is an AquaMedic 2x250 1x150 10,000k MH. I acclimated them, placed them at the bottom of the tank (135 gallon) for a day and then moved them up to the top of my reef. Some are open, some are short and chubby, some are long and stretched out but haven't opened.
Levels are good. Is this normal or should I move them? (please see picture...)
