half breed Neolamprologus brichardi-leleupi

I have a tank with J. dickfeldi, N. leleupi (spell? Lemon cichlid), and N. brichardi. The brichardi harassed badly by the leleupi and chased aggressively usually into the top corners. The leleupi and dickfeldi get along and seemed to have paired. Saw the dickfeldi digging a cave. About 3 weeks ago I caught and put the brichardi in another tank so it wouldn't get beat up. Today, I noticed a few tiny fry at the bottom. I wouldn't imagine the Julie could crossbreed with the neolamprologus bc different genus but the brichardi was removed about 3+ weeks ago. I'm wondering who the parents are I didn't expect interspecies breeding! Not sure if I can find this post again please email -confused bio teacher here!!
