I own mostly Zoas, and I’ve never seen this before which is why I am asking about it. So one of my zoas I have had for roughly 7 months, and it was always been doing amazing. Just in the last couple of days, some of the polyps are stretching much more than usual, and they are shrinking up at the ends. Only change I have made recently is adding a new bag of chemi pure elite, but do to how this zoa reacted I have since taken it out. Any ideas as to what could be causing this?
