I'm going to need better labels for the next auction.

I brought the 5 Cyno. Afras to the MCA auction. They were part of a group (juveniles and adults) I purchased in September from a breeder who is scaling back. This is my first time keeping them, so I'm not exactly an expert.
The adult females I have (including one that just hatched a group of fry) all seem to have the iridescent spots. They will vary in color between individuals and mood, but very similar to your pics. The two dominant males don't show the spots. There's a subdominant male hiding somewhere in one of my tanks I haven't checked, but he stays pretty scarce.
My guess is that it is just a loner type afra. It may be some fluke when I got them originally, but I think it's not very likely since he tends to keep even his grow out tanks stocked so similar colors aren't together.
