Someone, somewhere has kept every fish available to us successfully in a reef. Often, these exceptions become the "rule". There are lots of these cute little humas on the market and they grow up to be typical triggers; big, quite aggressive and not reef safe. IMO, the only triggers I would consider in a reef are a sargassum, blue jaw, or crosshatch. But, bottom line, I really don't consider any trigger to be a good reef fish. Too bad, there are sure some great looking triggers.
