I am 90% sure the fish in the last picture is an electric blue...something. It is not an electric blue johanni, I am sure of that, but do not know if there is another part of the name that I am missing. I see electric blue hap, but still doesnt look exactly like yours. All I can find is a profile with a pic that almost matches exactly with the title of the fish being "Electric Blue Cichlid".
Hope that helps a little bit.
By the way, how old are the fish or how big are they in inches? I ask because the bright orange one looks like the male coloration of a P. Kennyi, but then again, I do not have the best resolution on my computer screen either.
