Hi im new here, just thought i would say hi. I have been reading on here for the past 2 or 3 days and I know that you all have great knowledge of fish. I have a 50g. with a baby oscar in it. I guess you could say its my first real large fish. I have my tank all set up/cycled and I just wanted some advice on what I can put in there with my new "big/little" guy. I really like the way that jack dempseys look, and I know that they will need a bigger tank within a few months if not sooner. Would these to fish be at war all the time?
