I would have posted on this earlier but the site was acting up again and couldn't get in here.
Well do you have any ideas which way you want to go? South American, central american or African? Looking for color, activity, both? What size tank?
Electric Yellows are a good cichlid to move on to, its easy to keep, colorful and active and will get you started on the african side of things. They are common too, so you shouldn't have to much trouble finding some.
