I have recently acquired a 40 gallon tank to better accommodate the featherfin squeaker that I purchased after being told it was a cory cat. I am looking for suitable tank mates for my featherfin. Some of the fish that I have been looking at include Bolivian rams, angelfish, and dwarf cichlids. This would be a planted tank with black diamond blasting sand as a substrate. I know that these fish have similar requirements but I was wondering if anyone has experience keeping them together. Could I keep 1 featherfin, a pair of angelfish and bolivian rams in the same tank? If keeping bolivian rams, how many would/ could I put in? Would 1 featherfin, a pair of angelfish and a pair of Kribs work better? Does anyone have other suggestions for stocking with a featherfin?
