Neolamprologus helianthis -or- Neolamprologus splendens?

I hope you enjoy yours as I am mine.  I have mine in a mixed tank with other species of Tangs and though all are rockdwellers they each have a slightly different niche-which makes a load of difference in how nonspawning fish get along.They hover over their rock pile.  Julies inhabit their rockpile. Chalinochromis cruise the total rockpiles.  Of course a little amore changes all of this.

Nothing have matched my Oscars as pets.  They are like coming home to a dog with its tail wagging.  But myTangs are starting to catch up.

Well, this is a highly debated question o na broad sense. In general, Tanganyikan Lamprologine relationships, phylogenetics, taxonomy, are a mess. Really, it's a paraphyletic group, a number of people have done phylogenetic studies, and all of them are sub par.

As far as N. helianthus, I believe is a distinct species. Hobbyists would agree, although some scientists have grouped them in with splendens and some have not. The most recent phylogenetic analysis, although not a very sound one in my opinion, does list them as a distinct species. The last phylogenetic analysis also used Chalinochromis sp. "ndobnoi". I believe this is also a valid species.

One thing to keep in mind is Konings Tanganyikan books are out of date. Although a useful tool, a lot has changed on the knowledge of Tanganyikan Cichlids. I don't believe he's published a new book in this field in at least 3 years.

I have a confession. I'm a cichlaholic.

Here I am again with another clear as mud question.  In Ad Koning's book Back to Nature Guide to Tanganyikan Cichlids, he lists N. splendens with the notation that N. helianthis is the hobby name for the species.  They sure look like the same fish externally.  i have N. helianthis, as far as what I was told at the time of purchase.  I have found a few comments on the internet after much browsing that the two fish are similar but nothing really to support Konings claim. I certainly tend to trust his knowledge. Yet (unrelatedly) he still seems uncertain as to whether there is a species Chalinochromis "Ndobhoi" or "Ndobnoi".

It is time to go to bed.  The light just timed out on my fish tank and I can't see the keyboard.
