What are you interested in? Plenty of options, but usually it's better to pick a style of setup you like, and go for that, instead of a hodge-podge of different fish which may clash.
If you want cichlids- what kind? There are many different cichlids from four continents and Madagascar. They all are very diverse and thrive with different conditions.
I would spend some time doing some reading on this site. Don't rush into buying fish- look at what others are keeping, consider how much work you want to put into it, and what you want to get out of the fish. Then answer these questions and we can give some suggestions
