Good cats to go with Pbass are Juruense/Tigrinus/Lima/Lince Catfish/Oxydoras Niger/Megalodoras Irwini would be good choices. They all should stay under 3ft as well. If you get the more aggressive catfish species that get over 1ft and are "readily available" they will end up killing and or eating your pbass most likely like marbled achara/brachyplatystoma filamentosum/jau/RTC/TSN. I bet it was something else in the tank that killed the Juruense and not a Pbass, almost definately infact. Personally I've kept TSN/Planiceps/Tigs/Juruense/Limas/Marble Achara/Piraiba/Iwinin with my pbass with no problems ~Trent
