I have a 240 gallon aquarium coming. What I would like to have for a stocking list is, black convicts, t-bars, red port acaras, fliers, rainbows, and possibly some cordyroys catfish and some giant danios for dithers. What I am not sure of is how many males/females of each. The tank will have a pangea 3d background with lots of driftwood to separate many terratories. In a perfect world, I could have all species breeding with all the fry being eaten up by the other fish. Is this possible or should I have an all male tank, or an all male tank with only 1 breeding pair?
