No, they are true SAEs.
I have not had anyone else so far tell me they look like anything other than true SAEs. I bought them through LiveAquaria which I have always had great success with and they assured me they were true SAEs. Looking at perhaps a dozen sites found on google, in every photo comparison I would say my fish look like true SAEs, and do not resemble flying foxes or false SAEs at all in my opinion. A couple of friends who have more fishkeeping experience than myself also assured me they were definitely true SAEs.
Also, as described in a couple of my replies above, usually the black band is very solidly black with no white reticulations whatsoever. When they were fighting, the black stripe grayed out almost completely, and when that photo was taken it was just beginning to get color back. Within the hour stripe was completely solid black again. Also, I don't know what you are talking about with the belly being slightly lighter than the back? Not exaggerating, I just went through 30+ photos on google images and pretty much every single true SAE had a lighter belly than back. Also have double-checked the sticky on this forum and I have no question they are SAEs.
