One of the ways I determine what the mixture cichlids in my tanks are done, is by how they are distributed in nature.
If they are found in diverse communities in nature, you might expect that diversity, might work in a community cichlid tank.
If that diversity is not found in nature, you might not expect it to work in a cichlid community tank.
East of the Andes, cichlids live in diverse multi-species communities.
And their aggression (or comparative lack of aggression) levels reflect this.
West of the Andes there are few different species of cichlids living together in nature, and their natural aggression levels obviously reflect this.
Just the names green or red terror names reflect this heightened aggression and intolerance of other cichlids.
So to me, combining Andinoara GTs types with Amazonian species does not seem to be reasonable situation.
I would also "not" combine Mesoheros festae types, with east of the Andes less aggressive cichlids,
As an example, to me, combining A rivulatus with the chocolate Hypselecara types, does not make geographic, or ..... aggression sense.
It also does not make water parameter sense, due to diverse conditions found on different sides of the Andes
The study below points out some of that same evolutional diversity
