How about instead of showing your faux awesomeness by tearing apart their grammar you try a new approach... it's pretty crazy... it's called... helping.
Since they're Neolamprologus sp. (from lake tanganyika) you will be able to keep them from neutral to extremely hard water. Ideal pH for breeding Tanganyikan is 8.5-9.0. I don't like buffers, but SeaChem's Tanganyika Buffer is a very good way to get your pH to those levels. Normally I'd just recommend natural ways to buffer your pH, but that is an extremely high goal to be achieved with crushed coral or calcium based rocks.
