Can it be done? Yes, but is it recommended? Some people will disagree with the idea of keeping them in full freshwater, but others say that it is fine. It can take an impact on their health over time, but I myself have seen them be kept in full freshwater without any issues for an extended period of time. I have also kept them in brackish water without issues as well, so it's ulitmately your pick. I don't believe that it should be too big of a deal.
 
They only get around 4", if memory serves me correctly, so a couple of them could go in a tank as small as about 30 gallons. I once had 3 of them in fully fresh and they did very well in a 55 with numerous tank mates.
 
I've always supported that they be kept in brackish.. but the guy at my local fish store keeps them in full freshwater and they are extremely beautiful and seem more active. Hard to argue with that.. he keeps them with discus, tetras, etc.
