Comments:
This species is the type species of the genus, however it does not have the typical characteristics of other Gymnogephagus. Gymnogeophagus balzanii have a more southern distribution compared to Geophagus (latitude between 12-27 degrees south which correlates to between the Cape York area and Brisbane) and should be kept in a period of cool water (12-15 degrees C) for two months of the year. Temperatures above 25 degrees C should also be avoided.
