Right now I am contemplating what to put in my 55 gallon. I am having a hard time making my mind up. I do have my heart set on cichlids but I do not want anything that will out-grow the tank. I am planning on doing a 3D background with sand as a substrate. What do you guys think? If you were setting up a 55 gallon right now, what would you put together? How many fish of each would you stock it with?
