Just got some blue zoas from a local reefer yesterday. He told me there were about 8-10 heads but instead the frag was more than 30+ mini heads! I don't really understand what it means by zoa growth. Does the "growth" part mean the zoas itself growing in diameter and get bigger or as in just multiplying? These blue zoas are pretty small compared to my others and would like then to get bigger in size. Also how long does it take to see some growth in zoas?
