Gymnogeophagus Balzani is an interesting species to keep. They are a relatively peaceful species although males can become increasingly intolerant of other males in their territories as they mature.
Gymnogeophagus Balzani is a mouthbrooder. The female can lay up to 500 eggs at a time usually on a stone or any other flat location. Once she lays her eggs the male will go behind her and fertilize the eggs. Once the courtship is complete she will pick up the eggs in her mouth and hold them until the babies are born. Once they are freeswiming she will spit them out if there is no danger so the babies can eat at which time you can feed them newly hatched brine shrimp. At the first sign of danger she will instantly put them back in her mouth. She will do this until the babies are no longer able to fit in her mouth.
