I agree, they likely get a bad reputation because they eat stressed/dying corals and not the actual healthy living coral. They are in my tank and 0% coral eating has been witnessed.I'm too lazy to research it, but I wonder if there is scientific evidence that the "1%" eat coral? I have a bunch in my tank and they seem harmless. One thing that I did witness though is after injecting majano with boiling water to kill them, one of these starfish was right on top of it for some time. So maybe the 1% don't even eat coral, maybe they just feed off the dead? (and yes, I know anemone are not coral. but maybe the same occurs)
