i have a sps dominated tank. with a ricordea garden. and wonder what are any restrictions i could face adding zoa's to my tank. i run my radions at 70% 14 inches above my tank, no i don't have a par meter but i am not burning anything. i have heard placing them in the indirect light would be best? but i am looking to get some corals to fill in the void areas where growing sps becomes problematic. lower light and less color. if i can fill these areas my tank will feel more complete. thanks in advance for any information provided.
