Went to gerbers tropical fish in dayton, OH yesterday and bought this pair marked as apistogramma viejita. After hours of searching on here and Google. I'm sure this is apistogramma macmasteri, since I now know Viejita are rare and 99% are macmasteri. I just wanted confirmation. Still very pretty fish, and the pair was 59.99, so pretty expensive too. Thanks for looking and looking forward to your answers.
