I think we both can agree individual fish will have their own personality so I will concede there is a small element of risk with any grouping of clowns. However, I really don't think that's the case with a young tanked raised trio. Regarding the social order here is a quote from Joyce Wilkerson's book, "Clownfishes":
"A typical clownfish social unit consists of one mature female, one mature male, and often a few adolescents who must settle for whatever space and food the adults forgo. The youngest fish avoids the chases and challenges of larger group members by signaling its acceptance of their higher position in the social unit. By intimidating adolescents and forcing them to expend greater amounts of energy to compete for food and a sheltering portion of the anemone, the dominant male and female maintain themselves as the larger and the only sexually mature adults in the group. Adolescents grow slowly, if at all, remaining small (only about half the size of the adult female) and incapable of reproduction as long as the dominant male and female are healthy. The loss of a resident adult is the adolescent's only path to sexual maturity within this hierarchy."
I think you are right in pointing out that my use of the term "harem" to represent a matriarcal social order is incorrect. But it's definitely not limited to just the sexual pair in the wild and they don't execute all non-sexual members. : )
