Not crazy about angel fish....I would like to stock a variety, but I really don't want smaller fishes like tetras...the cichlids looks cool.
For something bigger, active, and with nice color African cichlids are hard to beat. For a 55g you could swing 6-8 of the smaller (4-5") variety. It's best to get them all at once, and all the same size, otherwise you'll run into territory issues when adding new ones later on. Make sure you have PLENTY of cover (rocks, driftwood, etc) so that each fish can have it's own spot. Resist the urge (if you have it) to give them feeder fish, they don't need them and you risk introducing disease into the tank. If you must, stick with guppies or rosy reds, no goldfish.
If you want larger-ish and fairly peaceful, Gouramis aren't a bad choice. Like any other animal you can get individuals who are more or less aggressive than normal though.
If you are considering Oscars, my advice is only 1 for a 55g. And really the tank is too small for just 1 (consider full grown size of anything you add).
Remember the general rule, 1" of fish per 1g of water, BUT there's a big difference between a 12" Oscar and 12 1" Neon Tetras. Use common sense here. Also, I always like the consider the length/width of the tank as well. I would try not to put anything over 1" fish length per 6" of tank length in a tank (ie, for a 55g, max length of no more than 9").
So max length per fish is 9" recommended?
