"Red Neck" is just a commercial name, nothing more. There are several different color morphs/populations of A. macmasteri. The wild form closest to looking like your fish are the "Rotrücken (Red-back)/Red-shoulder Mac" A. macmasteri. Males of this color form look very much like your male, but the females look like typical wild A. macmasteri.
