Exciting! If I remember correctly, you've been working on this tank set up for a while, right? I have Ps. Williamsi, Cyno sp. Hara, and Labeotropheus Trewavasae in my 125 gallon right now. I like where you're going :thumb:
The fifth species: The hara might have trouble coloring up if you go with Demasoni. Rusties would be fine I think. I don't know anything about petrotilapia or the Joanjohnsonae (is this the same as Lab. Textilis?). Tropheops are very aggressive, but you can handle them in a 125 gallon tank. I'll suggest one other option that works in my tank and should work in yours because much of the stock is the same or similar: Pseudotropheus sp. Elongatus 'Spot' (or sometimes called "Elongatus jewel spot." The males have the same colors as Demasoni, just less blue. Females are drab brown, though.
Great choice! My only comment here is that their color is closer to an olive-green than a yellow. Definitely a hard-to-find color for mbuna.
The only issue might be the Met Estherae (blue), but since this is a 6-foot tank, you might have enough room for them to coexist without issues. I would be wary about saving fry from those two groups, though. I'd be less worried if you went with the red male instead of the blue. Or alternatively you could stock Met. sp. Msobo or Met sp. Membe - these males are a bit more distinct from the hara, but still have some yellow-orange with the females.
