SILVER CICHLID (Paraneetroplus argenteu)

An aggressive species, especially towards conspecifics. It may be possible to successfully keep this species in a community of robust Central American cichlids, if enough rock and bogwood is provided to form sufficient territories for all the fish. There is no guarantee of success if trying this. A bonded pair will often live quite happily together but care should be taken to ensure the female is not bullied.
