I cannot be sure on labelling your cichlid Xystichromis sp. "Kyoga flameback". In all honesty I approached Samaki with identification information on the group I maintain. His identification was correct and was later confirmed by Dr. Kaufman. I had been refering to my fish as "Nawampassa all reds" incorrectly; the initial field name given was X. sp. "Kyoga flameback". Anyhow, regardless, I have found that dominant males display much of the red coloration in the dorsal, the mid flank line is much thicker than in your fish, and mine lack the strong vertical barring. The barring on the head is much different as well. Perhaps Chris could chime in here and offer some insight as well.
