I have seven 6-10" mpimbwe fronts in an 8' 240. Three are wild caughts the rest are F1s. If u have the space and can afford it I'd go for a standard 8' x 2' x 2' like mine. Sometimes when I walk up to the tank my fronts dart in the opposite direction and occassionally hit the acrylic even when they head long ways across the whole 8'. Fronts are skidish fish. Any sudden movement scares em and with a larger tank they are less prone to hurt themselves. Having a taller tank will allow you to keep an additional front or maybe two but that's about it. Also, don't keep anything sharp in your tank, drift wood or rough rocks and the likes, as your fronts may lose an eye when they take off.
And I'd go for zaires. My personal preference. The blues are just significantly more vibrant. In my opinion they're just gorgeous.
Good luck and keep us posted.
