So far so good, that could change but I'm confident. I look at these fish not as unsafe, but having a specific need that mat need to be met. It's not universal or guaranteed, but its how I roll.
It's a matter of education & identifying a need. One example is my Coral Beauty Angel - known to be one of the safer Pygmy Angels, which as a grazer, I keep well fed to diminish its need to pick at my corals. Really, much aggression we see is people feeding too little or believing incorrect sticking "guidelines".
My next addition will be a pair of mandarins that will be trained to eat prepared before going in the tank.
My final addition will be a Blue Throat Trigger, added small, last and ensuring plenty of caves for it to hide in.
Too many people just throw in a fish, don't accommodate it's needs then fire it back out once it causes trouble.
