If you are going to move the kenyis then I would say give it a shot. I know people say water parameters are different... but I've had them both in what comes out of my tap (mind you my tap is very hard). O's come from soft water but they are hardy fish and live in just about liquid rock here in SoCal. Then they are gonna say but the diet is sooo different.... That's not true for predatory Haps... they have a diet closer to a jag maybe even more carnivores since they are strict piscivores (sp?) in the wild. Malawi predatory haps will have a temperament on par with that JD imo.. When i had mine i didn't have problems until i tried mixing them with centrals on the level of Salvini and Louiselli. My Livingstonii put up a good fight against the Louiselli but the tides were not in his favor and he eventually would have died (but it was close enough to maybe be an individual fish basis, neither on would always win, it was in the air.) The Salvini totally dominated the tank as he grew and would have killed every fish in the tank if I didn't get rid of him.
Also, by the body shape and color of that fish in the picture above I'm 75% sure its a Livingstonii. Could you post a clearer picture of him?
I'd add more predatory haps; N. Livingstonii, N. Venustus, N. Polystigma, N. Fuscotaeniatus (These are monsters, I had one, they will soon be reclassified as Tyrannochromis), D. Compressiceps (males are impressive and can hold there own unlike what some people say about them, and they can easily outrun any fish you add to the tank if it can't, also they tend to hang around the top of the tank and look different so other fish don't pay much attention). I would say Red Empress but idk about the food requirements due to it needing more percent veggies in its diet. Maybe a Blue Dolphin but I hate how they look.
Also, if you add more Centrals id do something on the mid or low aggression spectrum tons of them out there. Wonder if Amphilophus Lyonsi would work... would add a lot to the color to the tank with the haps also in there.
