I have this piece of Zoa for a month or so. Initially polyps opened fully forming a ball but I see that it's slowly getting smaller. So I dosed aquavitro fuel and can see the mat started to pop out new polyps which I think is a good thing, but all the polyps which used to be big became smaller. I can hardly keep zoas except palys. Hence, hold off buying nice zoas for now. Sent from Singapore Reef Club mobile app
