Agreed, it does look a lot more like a C. azureus, than a S. fryeri, but that's the problem when common names are used, especially coming from a body of water that has so many different "electric blue" species. A couple old shots of one of my male azureus.To me it looks like Copadichromis Azureus or Azul or even Aulonocara stuartgranti Chilumba
