lake victoria species are very hard to come by. most are on the endangered species list. the most common of them are the haplochromis obliquedens. i have these and ruby greens. they can be kept with some of the malawis since the two lakes are similar. they are mouthbrooders and best kept in groups of a minimum 3 females per every male.
you usually can find them on aquabid. some of the online breeders also carry victorians.
