Bought my Zoas slightly more than a month ago, everything seems fine, with my zoas opening up everyday 100%. Only last week, i noticed a small section of it not opening completly and some not opening at all. Also notice a lot of these small creatures with spikes on their back resembling the color of my zoas crawling about. Anyone know what parasite it is and how to get rid of it. I can't remove the zoas from the aquarium because it had started spreading onto other rocks.
Please advice , anyone out there.
