can i mix my geophagines(geophagus stiendachneri , geophagus sp. red head tapajos, stanoperca leucostica, guincara geayi )with some pink tail charachin Chalceus Macrolepidotus and some Ctenolucius Hujeta?
A lot depends on how big the tank is and how well fed they are. I have a 3" jewel that lives with 3 8" red terrors and a 10" midas and so on but they are in a 265gal tank and well fed.
