I know this is probably the most common thread on this site, buttttt I need help

So for my birthday I'm hopefully getting a 55 and have zero clue what I want to get. As of right now I have 2 peppered cories, 1 bn Pleco 2 German blue ram, and 2 keyholes. I plan on keeping all of them, and I kinda want like one big centerpiece fish.

Sorry my iPod was freaking out, I also have 5 glowingly tetras. I want to stay with cichlids so ill probably need more South Americans. Lets hear all of your guys suggestions. I'm open to pretty much anything.
