bluejaws, crosshatches, nigers, pinktails, and sargassum triggers all will eat reef fish that are small enough
i have yet to see my triggers nip at any coral and are actually quite skittish, my male is thick, bright, and is most likely the best looking male bluethroat i have seen, he is about 5-6" long and has grown about an inch since i bought him in february, the female i bought at about 3" and is actually growing at the same rate as the male, i have mine in a 125 and will be moving them to my 700G tank when its complete
the key to keeping them happy is giving them a variety diet, i have about 10 different foods that i feed the tank in a cycle over a week period
here is a new picture of my male
the female
the pair together
