The valid scientific name for your fish is Aulonocara stuartgranti "Chitimba Bay shallow". The common name is the Bi-Color 500 and a previous trade name that it was traded under was Aulonocara sp. "maulana". The reason that the proper location is "Chitimba bay shallow" is that a very similar and popular fish in the aquarium hobby is from there, Aulonocara stuartgranti "Chitimba Bay deep", better known under the trade names Aulonocara maisoni or White Tip Maisoni peacock.
Hope That Helps,
