Well, I know for sure that they are at least in the same genus, if not the same species. There are quite a few differances, but with rift lake cichlids the classification is very confusing. I have seen pictures of nearly identical fish labelled as
Neolamprologus pulcher but one store I have been too (one of the few I would find credible enough to go by what their labels say) has them labelled as "daffodil brichardi". Some species from the area have over 20 different color variations depending on their location, yet some that appear exactly the same except for small color differences are seperate species....
The female lacks the yellow gill spot present in normal brichardi, the line between the eye and the gill is a vertical curve rather than a small horizontal line, the females eyes are ringed with yellow intstead of a solid blue, the female has a blue iridescent curve under her eye where the male has a large pattern covering the whole side of his jaws, the female has vague horizontal orange lines down her side while the male only has a few orange flecks, and finally, the female's fin streamers are a metallic blue instead of an off-white like the males
's. Of course these could all be location variations.
Whatever she is, I would like to get her a mate that is the same color variation and breed them instead of mixing colors.
