I bred these fish several years ago in a 6'x2' tank with other malawis present. They are a very impressive and powerful fish when large, the males fins are beautiful. They are very fast swimmers, I would have prefered to have had them in an 8' tank to give them more room to stretch their fins ! They need (if I remember correctly) an area on the tank floor with enough room to court and breed, and plenty of swimming space for initial courtship. I can't remember if the male is overly aggressive with the female, but I seem to recall some chaos in the tank with the other residents. These fish have big mouths and will eat (and hunt) any fish they can fit in there. I recall feeding mine on standard malawi food (pellets and flake) plus frozen shrimp/mussel/fish. I haven't seen any available in my LFS for quite a few years, but I'd have them again, and would recommend them to anyone with a large enough tank to do them justice.
