I did not know that (They showed no sine of this when I kept em (seemed to love the usual Lamp fare of fish foods the fishyer/shrimpyer the better)
). Yep I guess thats why.
To be honest few African cichlid genera are not messy (polyphyletic) esp the older ones (or in this case a renamed old one (those chucked out of Lamprologus that have the ossified ligament thingy).
It has been known for some time that according to mtDNA sequence analysis, this genus is prob polyphyletic. It is likely that it will be revised eventually; as Variabilichromis has been split off, at least some of the more ancient lineages currently placed in Neolamprologus are prob worthy of separation also.
Mind you not everyone even follows the Neolamp/"exLamp" split (still saying the genera of the tribe Lamprologini, are just Altolamprologus, Chalinochromis, Julidochromis, Lamprologus, Lepidiolamprologus, Neolamprologus, Telmatochromis and Variabilichromis) and the "exLamprologus" (Konings, 1998) do not even have a good name nor a type species.
Thing is while genera are clearly different in their morphology, habits and ecology, (and could be further separated) gene flow between genera and is common enough due to extremely low postzygotic isolation. Males of Neolamprologus apparently have always readily and successfully mated with females of other Lamprologini they found ready to spawn. And not only do such hybrids seem to be fertile, new species appear to originate from such interbreeding.
