I just purchased a 125 gallon(72x18x23) aquarium. I have a fluval fx6 for flirtation. I have two firemouth cichlids and a bristle nose pleco already in a 55 gallon that I will be adding to the 125. I also would like to get at least one Oscar because they are my favorite fish. What else would work with them? I will be cycling aquarium before adding fish just want to brainstorm and get a stock in mind. Also should I get dithers like giant danios or silver dollars, or should I wait and see.
