I have a 10" Imperator that was acquired with HLLE. I'm considering adding him to my 300g reef that has a mix of fish, mostly Tangs, NO ANGELS, all of which are at most half his size. He was in a FOWLR tank and was the dominant fish along with a large puffer, 2 large angels and triggors. He mostly just chased the other angels. I realize the dangers concerning my corals however I'd like your opinions regarding how aggressive the Imperator will be towards my other fish. thanks
