I think any trigger is going to potentially do damage to a reef tank. None of them are going to be reef safe gauranteed.
I had two blue throats in my 120 and they did great for a while. But over time both died and I am not sure why. Both were extremely healthy looking, active, ate well etc. But one day I found them on the bottom of the tank about 2-3 months apart. All other fish were fine. I will not be getting another until I go 300 DD.
