Two of anything is risky when dealing with possible aggression.

People need to get over the quaint notion of using the word "fine" to describe a new fish introduction just because it doesn't produce any aggression within the first five seconds.

This.

It's a matter of dispersing social quarrels between individuals, which 2 doesn't do sufficiently because the social quarrel reaches the end of the line whenever one fish engages in it.
Generally the recommended minimum to disperse the quarrel is 3-12 depending on species, with the minimum being higher the more aggressive the fish is.
