Most cichlids found in our lfs's tanks, are not of the wild variety and usually do not require that we duplicate their exact home water chemistry. Many cichlids, whether they be Tanganyikan shell-dwellers or Dwarf apistogrammas, if they are in our lfs's tanks, chances are they have been "farmed" and are quite acclimated to a rather neutral water chemistry.
I have many breeder colonies and most are set up with neutral water. There are some fish, however, that simply will not do well unless water conditions are at or near their native parameters. Cichlids, I believe, are very versatile and can not only survive, but flourish, in water chemistry different from their native home waters. I must admit that I also keep many colonies that have water that is more closely approximated to their native waters. My discus, for example, are kept in tanks that have a pH of around 6.8. My Victorians, which are wild caught, have a pH of around 8.2-8.4. My Malawians are doing excellent in water with a pH of 7.0-7.6 and most of these are F1 or F2's. My Tanganyikans are kept in water with a pH of around 7.0-8.0, depending upon the species. Many of my South Americans are dept in neutral pH of around 7.0 (straight from the tap). My Apistogrammas and my rams are kept in water that has a pH of 6.8. They seem to have better spawns and have a higher survival rate at that level.)
