help me with my pink palythoa
I have a rock with 30 polyps,pink palythoa, for 6 months. For the last 2 weeks, 2/3 of the polyps have been closed. Tank parameters and all other corals in the tank are fine. I think that some pest is bothering them. I was considering giving them a fresh water/iodine dip. Is this right to do or do I need to do something else to figure our what's bothering them?
