I was hoping to set up in the near future a tank devoted mostly to Predatory Catfish, the dimensions would be 96 x 24 x 25. I was hoping to focus on less commonly seen cats and wanted some suggestions for cats that would inhabit all strata of the water. Some of the stock I know I want to include that would affect the cats chosen would be Geo's(either brasiliensis, altifrons) and I was going to keep a group of Trachycorystes Trachycorystes. I was considering Ageneiosus marmoratus or magoi and the little more common Sorubim Lima/Elongatus as upper level dwellers. Does anyone else have some good suggestions for rare cats that'll be fine longterm and fairly unprobematic comm'd together?
