The Sargassum and Crosshatch are also suitable species for a reef tank. Unless the tank is extremely large, triggers aren't a good choice for a reef system. They are very active, create a lot of waste and are unpredictable as they mature. Even the planktonic species can get an attitude. The black (Durgeon) trigger and niger, while planktonic, can become very nasty and they are imposing fish when adults that need huge systems. I wouldn't consider either of these personally.
