I'm kinda new to the fish tank craze and must admit I'm hooked. I started 6 months ago with a 50 gallon and peaceful fish. I just prchased a 220 gallon freshwater setup. I would like some ideas or recommendations for the fish. I'm leaning towards a couple of Colombian Sharks so I'll probably go brackish later. Any ideas of tankmates? Is there a brackish Puffer that is okay as a mate? Love to hear all your input. Nothing that is too difficult to maintain. Open to all ideas.
