Okay so I'm thinking about buying a 55 gallon tank soon. This would be my first tank (other than a betta a few years ago) and I'm interested in cichlids. Out of the American cichlids, which would be happiest in a 55 gallon. I'm fine with either a couple larger cichlids or smaller cichlids with other fish. What do you think is the most visually appealing combo of cichlids for a 55 gallon?
