I have seen similar fish from many different river systems in Peru. Other than being a Peruvian population of A. bitaeniata, it is impossible to say where the fish originated.
Here is a link that shows two slides, the first is a Apistogramma bitaeniata 'Mamuri' and the second a wild bitaeniata unknown origin. They are the same age but the wild is twice as large as the Mamuri. They are very different.
