Setting up my first African river tank

[jgentry]

I was given a 60g tank 48 X 12 X 24. I have kept SA/CA cichlids and saltwater for many years and wanted to try something different that I low mantinance. The tank is decorated with a piece of drift wood and some branches from above. Here's were I need some help, what other fish can I have that match my biotope.

Here's what I have
Kribensis pair
Buffalo head pair
African butterfly fish X2
Leopard tconomis (that isn't spelled right, but it's something like that. It's a small black and white spotted leaf looking fish)

I think what I have so far are correct for the biotope, am I right?

What else can I add from this same area. I was thinking a school of congo tetras, but that's all that I can come up with. I'll try to get some pictures of the tank posted tonight.

Thanks for any help,
jgentry

I'd worry that the buffaloheads would relentlessly attack the kribs, which are a much more delicate species
