New Congo biotope help needed

[ayeo77]

Hi all, after 10 years of keeping Central American cichlids in a large 8 x 3‘ tank, I’ve decided to go for a change of direction to renew my interest in the hobby. I’d like to go with a west African Congo biotope and so far have got 15 Congo tetras and a few localised barbs. I wondered if you could all give me some advice on whatI could keep in such a such a tank in terms of pairs groupings and species, as I’ve had much confusing advice out there and also seen conflicting information when doing research online. I’m interested in krib species, Hemichromis cichlids, and any other dwarfs you can think of that are compatible in such a tank. Blockheads? Nanos? Southern mouthbrooders? I understand that Hemichromis may be a tricky one with other sp. thanks
