I found it's very hard to make all zoas happy in my tank. I used to have some very healthy tubs blues, armor of god, fire and ice in my old Biocube 29 with LED lights. After I moved them to my new tank which has 6 39W T5 lights, they are not doing well. Now all my tubs blue closed and armor of god won't fully open. fire and ice dead. But all other zoas (more than 10 different ones) are doing better than before. I also bought some nice light blue color zoas with yellow and green skirts from Aquarium depot but they also closed. water parameters are good. Tried different locations, water flows and lights, seems only make them worse. Any suggestions?
