Hello! I'm from North Carolina as well.
From what I've read those fish are best in schools, meaning like 6 or so of each. I'd start there and I'd probably consider some sort of bottom feeder Pleco or similar to help in keeping the algae in check. Be careful which Pleco you choose as many get very big very fast. Also some Plecos do eat smaller fish, research carefully! You may decide on some Corydoras Catfish instead.
You probably want some sort of "centerpiece fish" to compliment the tank but small schools of each of these fish will make a nice community in my humble opinion. A very nice centerpiece fish would be something like a Sailfin Molly, he should go well with the others here but do your own research to make sure. Hope that helps!
