Any specific recommendations?If it were me, with your water parameters, I'd either go with small Central Americans, or South Americans from outside the Amazon basin.
The Acara's from west of the Andes, or Gymnogeophagines or other Uruguayan, Agentinian, or southern Brazilian species.
Your type water will not directly kill Amazonians, but......they are often prone to bacterial diseases in mineral rich, high conductivity water as they age.
This is why we see so many posts about HLLE disease in oscars, Amazonian Geophagus and other soft water cichlid species.
There are Geophagus from west of the Andes Like G, steindachneri, pellegrini, and crassilabrus, and the Gymnogeos that are more adept at handling higher conductivity, and the minerals in your type water.
Are gymnogeophagus out of my skill level/care requirements?
