I think it is in this family of Aulonocara....very beautiful fish after looking through my book this is the closest i came up with.......This fish is one of the many subspecies of fish originally grouped together as Aulonocara stuartgranti. Included in this subspecies are Mdoka, Usisya, Cobue and Flavescent and others. Re-classification of fish is constant and the Aulonocara is no exception. Some of these fish have been renamed Aulonocara hansbaenschi.
As far as I know, the Ngara is still classified as a stuartgranti, but reclassification of this fish is not beyond reason. When this fish was first imported into the country it was called the "flametail peacock". This name has recently resurfaced with a whole new connotation, higher prices. A. Ngara "Flametail" now seems to mean that the fish has been bred for color.
There is an intensely red strain of A. Ngara in the Chicago area, originally bred by Rick Boester, that is sometimes referred to as A. Ngara "Red".
