So back in March I got some zoas from a guy I sold my copperband butterfly to. They were not doing good in his tank, asked if I just wanted them, so I took them. Figured I might be able to get them back in good health and if not, they were free. Its been two months. They open up a little but they do not extend off the rock. Every other coral in my tank is thriving and has noticeably new growth in them except these zoas. I did just switch two weeks ago to leds from t5 so I am still getting them acclimated to the new light. That has been the only change. Any thoughts or anyone want to take them off my hands?
