Well as for right now we have several species of african cichlids and some new world too, but we have raised some whiptail catfish and some more. We recently got Mpimbwe Frontosas, Salvinis, Festivums, Geophagus"Tapajos", a bit of community fish and some Shrimps. So a bit of everything but the main idea is getting hard to find species. I want to set up later a Discus colony and try my luck on them tho.
