Explaining "mixed tanks", to a hobbyist that is clearly not in the know of how many African cichlids are sourced, and sold, is not bashing. I am not a purist either, I have even kept fish such as flowerhorns in the past, and currently have a parrot in one of my tanks - but when it comes to African cichlids, if you do not know the source, then almost anything is possible, and in some cases more than probable. You can argue this until you are blue in the face, but it won't change reality.
When I was keeping and breeding African cichlids, if the vendor couldn't tell me the source of their fish (not just the species) I passed. If I was considering say S. fryeri as an example, I would also need to know the collection location, and have some sort of provenance back to the wild. There are more than one "type" of S. fryeri in Malawi, and this is quite common in the Rift Lakes. So to ensure pure geographical blood lines, I would only breed fish from the same collection location in the lake. This is what I consider the proper manner in which to breed all species of fish. Otherwise all bets are off as to what you are buying, and eventually passing off to other hobbyists.
Doing so removes any & all doubt from hobbyists such as yourself, who are then left posting on online forums, asking questions about what fish they bought. It elevates the hobby - unlike those who simply toss a bunch of fish in a glass box, and with whatever excuse they want to use, inform their customers that their fish are all legit. In the world of cichlids, especially African cichlids, talk is cheap, and hybrids are everywhere. Caveat Emptor!
