Is a "Red flame" Centropyge loricula or Neocirrhites armatus or what??
I have all but the Halichoeres chrysus... There is no such thing as a reef safe fish. Every fish can potentially destroy something. It's just that what are you willing to sacrifice?
The Coris gaimard has eaten some shrimps, and will kill everything that it can when it comes to crabs, shrimps and hermits. And the chrysus is rather the same, just smaller. All Centropyge species can nip at corals, but may never do that... If the flame you are talking about is the armatus, the it should be reef safe. Mine is...
