Hello. I'm just curious on this one, don't have the fish or the tank but it's fun to dream! If one were to build a 4'x4'x10' plywood tank or have a similar footprint acrylic would there be any reason why a redfin pickerel couldn't be housed with cichlids of similar size and other SA fish? I'm thinking the tank would be dense with driftwood and boulders along with plants. Other fish I'm thinking would possibly be an arrowana, tenemesis cichla, maybe a tiger shovelnose, etc. What are your thoughts?
