Is it possible to keep a school (7+) humbug damsels (Dascyllus auranus) in a big tank (187 gallons) along with other semi-aggressive fish (a school of 9 yellow tailed blue damsels, 3 smithi damsels, a massive royal gramma, an extremely aggressive pair of true percula clowns, a bicolor angel, and eventually a yellow tang and a pair of twinspot hogfish)? I have kept the twinspots before and they were pretty fiesty, and my current bicolor is a pretty domineering fish. I read that they are less aggressive if added after other smaller fish and are kept in bigger (5+) groups. On WetWebMedia it says that humbugs should be kept in groups. If so, I'm going to pick up the school tommorrow.
