South America; Argentine humpheads were first discovered in Paraguay by Heiko Bleher.
Males will develop the nuchal hump and have an extended dorsal fin. Females will be smaller than the males with less coloration.
Argentine humpheads will need hiding places for spawning, plant pots are ideal for this. The female will tend the eggs while the male will defend the spawning site form intruders.24- 36 hours after spawning, the female will pick up the eggs and start mouth brooding. The fry should be released after 3 weeks, at this stage they will already be free swimmers and can be fed on newly hatched brine shrimp.
The expected life span for Gymnogeophagus balzanii is 5-8 years.
Gymnogeophagus balzanii demand the highest water quality; large weekly water changes must be performed. If the quality deteriorates they are prone to hole in the head disease.
