My dragon face pair lived with multiple triggers, tangs including Vlamingi, Unicorn and a few other big tangs with no issue. I also have large carpet anemones. Had them for over a year before I lost a large number of fish. I currently have one in my 350 with 4 eels, angels, tangs and a Thais. They are hardy and fish ignore them. What they need is a established pod population to grow. By the way the triggers I had were a Niger, crosshatch pair, Hawaiian pink tail with them. I also had pairs of yellow and red pipefish along with a black/yellow pair. One of each pair passed after 6 months and the last two went in the wipeout :(
