so the Maingano (or electric blue Johanni) is a type of Johanni, I believe that in the Maingano, both the males and females are the electric blue. In the normal Johanni, the females are orange. I don't really know much about the Maingano as I've never kept them personally, although I've read that they are somewhat less aggressive than the regular Johanni. The perileucos I am not familiar with. To me, looking at pictures on the net, it appears that you have electric blue Johanni or Maingano, and the first picture is the dominant male and the second one is a female or nondominant male. Hopefully someone who has had them can tell you more.
