Are these what some call the Electric Blue Dempsey?
I have a typical Jack Dempsey male that has the inverse of color in your fish. I'm really curious of the nature of these fish as it would seem they may be amelanistic such as the trait in some reptiles....i.e. African Fat Tail geckos in which the amelanistic version retains the pattern of the normal African Fat Tail but it's colors are a dull lavender and orange pattern as shown in the image of a normal and amelanistic. What do you think?
