The only fly in the ointment might be that balzani more temperate species, come from cooler areas of southern Brazil and northern Uruguay are over 3000 miles south and have lower temp preferences than the tropical species like northern Geophagines, and Heros.
Depending on the ancestral source, balzani may like temp drop in July, Aug Sept, that wouldn't be appreciated by th equatorial species.
I have found that more temperate area cichlids become prone to fungal and bacterial infections if kept at constant warm temps.
I kept my balzani in room temp, unheated tanks, due to these geographic differences.
