I have extreme zoanthid growth and killed every acro in my tank. Now only keep LpS and softies. Having great growth.Trying to balance too much light for LPS with just enough light for SPS in my mixed reef means that my acros are slow growers but they’re growing happy, brightly colored, and healthy. The only one I’ve lost so far (fingers crossed) fell into a hammer coral and never fully recovered. As long as you’re on some kind of dosing and testing schedule that keeps your alkalinity stable, and you keep nutrients in check, they’re not too hard to keep. I’ve had a harder time with zoas than acros to be honest.
