The issue is fish of the same species, when that species is highly territorial to the extent that most cichlids are (by comparison to other fish like characins or cyprinids). As it notes in the profile of angelfish, they should be acquired as a group at the same time, preferably when young. If you have 2 angels in a 55g tank and they are there for some time, they consider that tank as their territory. Ading another angel is bound to be problematic. Same with Bolivians.
Adding characins (hatchetfish are characins) is not the same, either within the species or with other fish. I frequently add characins to existing groups, they immediately settle in, happy to see more of their own species. While all fish are territorial to some degree, with characins this is usually--not always--insignificant.
