Is my queen the cuplprit?

[SaltLife]

I have a queen angel that I got as a small fish the size of a quarter and now it's about the size of my hand. I am unable to grow ANY corals or keep any corals alive. I was once able to grow anemones and GSP (I know, everyone's favorite) but now I can't even seem to keep them alive. I've checked my tank parameters over and over and they are in line with a normal tank. I am down to this queen for the reason everything I put in my tank these days dies off within a week. I've read these angels are not reef safe and I have seen it nipping at my corals. Is it really killing my corals?!?!?!

I would say yes especially that size of a queen angel it can do some damage quickly to any and all corals in a tank
