No one has mentioned how these fish would NEVER live like this in the wild. They're being forced to endure something intrinsically unnatural in order to override their instincts, their true nature, which is to be territorial and grouchy. Keeping CA/SA cichlids in a school is a gimmick, a jerry-rigged trick to cram more fish into a tank.
Keeping nitrates consistently low in that tank will require divine intervention.
