Depends entirely on your style. Several types of livebearers, characins, gouramis, loaches, cories, and many other types of fish are all very interesting and readily available and all can be great fish but you need to be the judge yourself. I'm personally a fan of the uncommon, but many enjoy the colorful community fish that can be found easily and will really make your tank look nice. You should really just look around and make your own call because it's a hard question for anyone to answer.

As far as the rams go I'm not sure of their behavior but I think you could expect them to be set up a territory and defend it (especially if breeding) and keeping a male to a female will help to decrease how aggressive they are
