My naso is probably the boss . But I have a yellow that just starts it with everyone else. Will start a fight just to start a fight. Hippo flashes a little now and then but goes to his spot. My (little tomini just stays outta the way) but does get a little sporty once in a while. Flame angel really doesn't care. They swim and hang out together most of the time, just little discussions every now and then
Lol how big is your tank!
