Umm, I'd avoid actinodiscuss species mushrooms in any tank with acropora. Try to stick to ricordea or maybe rhodactus. Actinodiscuss breed too quickly and rapidly and float around the aquarium when they do. They can land next to an SPS colony and burn it to death really quickly. I'd also avoid Goniopora, as their captive survival rates (especially when smaller) are exceptionally pooor. Nobody knows why but they just wilt and die even in some of the best tanks with the best keepers...
