Im not a African cichlid person myself but if set up properly they can look amazing, in that tank you could do a lake tanganyika tank with shell dwellers, cyprichromis and calvus with a tangayikan spiny eel. Or you could make it a SA cichlid tank with a group of Cupid cichlids, angels and severums with cory catfish as bottom dwellers. These are just some ideas as the tank has the same footprint as a 125 so you have lots of options
