Apistogramma

[MJR]

I bought this pair a few months ago under the name "Apistogramma Viejitas" but as most people know, there is quite alot of mix ups between that species and Apistogramma Macmasteri. Anyway, i'm not sure if these are actualy viejitas.
Anyone have any ideas?

It probably is a domestic strain of A. macmasteri. It looks very much like the wild Red-shoulder Mac/Rotrücken form of A. macmasteri and nothing like the real A. viejita.
