| || | How big of these fish are you willing to buy? Care requirements vary as the juvenile ones less than 4" in diameter are far more sensitive than the adults. You may need to start raising the juveniles in a barebottom setup with daily water changes and multiple feedings. Adults are much easier to keep. In your situation with the 75g, you would be better off buying discus that are above 4" in size. They are more expensive but IMO, they're worth it minus the tedious daily water changes that juveniles require to avoid stunting them. Tank mates must be able to tolerate their required temperature ranging 82 to 88 degrees Fahrenheit. In my discus days, I stick it to 86 degrees. Too warm for most fish unfortunately. You can try combining bristlenose plecos, rummy nose tetras, cardinal tetras and sterbai corydoras with discus. These few ones are tolerant of the discus' required conditions. As for pH, it is not an issue with domesticated fish. They are quite accustomed to it better than the wild forms. And Jack Wattley also keeps his discus in pH of 8.0 last time I checked, same with mine. As for foods, that's not really an issue. They will eat just about anything once established in your tank. Flakes, bloodworms, shrimps, the works.
