Who has successfully kept the fish mikrogeophagus ramirezi aka German Blue Ram in a pH of 7.5 with a dH of at least 7 or 8? I’d love to keep this fish but would rather not have to soften the water for them if they don’t need it. I’m not looking to breed them, just keep them. I'm aware that bolivian rams are easier to keep, but I just don't find them nearly as pretty.
