I have zoas and acros. My acros are high up and zoas low. Wouldn't expect them to every be placed side-by-side. Good acro parameters tend to be counter productive to zoas. My zoas melt and grow back frequently due to low nutrients.
My zoas do great in my sps grow out system. Only issue I encountered is too much flow for some of them. Bottom of the tank tends to be a good solution for zoas in a mixed reef
They have always been fine for me. One thing that happens is the spas can shade where the acro encrusts and it dies back and the zoas slowly advance that way but it’s not too bad.
