I have a 90 mixed reef w/ a yellow tang, melanaurus wrasse, 2 perculas and a yellow tail damsel (I know! but it's 12 yrs old and my first fish) and a 75 sump/fuge. I would like to add a gold flake angel and need some learned opinions on compatibility. I am ok w/ the possibility of coral nipping but don't want to plunk down $$ if the consensus is a 'clear no'. Thanks in advance.
