Those triggers should be good together forever if there gettin along now. But I may be worried about the undulated, keep an eye on him. I have seen wussie undulateds to. I am not familiar with the eyeliner trigger can you describe what he looks like? The damsels will be lunch and the flame will, and what type of puffer do you have, what type of wrasses are they? If they are large aggressive wrasses they would do good, but if they are dwarfs they will become lunch. If the triggers are doing good together now they should be good w/ eachother for rest of their lives like i said before. I have in my 240 that are triggers, 5 in. niger, 4 in. queen, 4 in. blue line trigger, 4 in. clown. They are all doin good but the queen and blue line get in there arguments at times. U may need room though when all your fish get full grown. But you should do good.
