With the SPS issues, you have to be here to see it. When things died it wasn't over a longer period of time. For example a SPS coral I had for over 2 years, just suddenly started losing flesh. I took it to Red Coral, we investigated and fragged what was left. By the time I got home, the frag lost half or more of the remaining flesh, and within an hour in the tank, the rest was gone. This isn't from any fish or critter.

Rick your coral losses are due to RTN, but RTN is a symptom and not a disease in itself, there are many potential causes. It's like saying you have a broken arm, there are an infinite list of potential causes for that, but the end result is the same: your arm hurts.
RTN can most assuredly be caused by stress induced by predation.
When you eliminate the impossible, of whatever remains, regardless of how implausible, the explanation is in there. You think it's implausible that the fish are to blame, for the longest time I held the same view in my tank .. but realistically it cannot be eliminated in either of our tanks. Things don't die for no reason, there is a reason. I'm sorry if you don't like to hear this
but I'm calling it like I see it: for the longest time you've had inexplicable losses, now we're getting a glimpse of something that could explain other things that previously thought to have no explanation.

Other SPS, same thing... They start dieing, I would break them off and lightly move them in the water and sheets of flesh would just peal right off. So this is nothing to do with anything eating them.

I still disagree. Once RTN starts it is it's own little beast.

If Dori, only eats the zoas, then I can live without them, as there is no way of catching her, and I won't destroy my tank to do it. I just hope see doesn't develop the taste for the SPS.

You can always a catch a fish, it comes down to techniques you employ if the need is there.

That fish would be dead by now if they were poison.

What's toxic to one kind of critter (mammals) might not be for another (fish). Fish have evolved alongside zoannthid for millenia, it's entirely possible they have built up immunity or resistance to the palytoxins that other critters might not have.
