Wild A. agassizzi, can we narrow down a location?

Hi, I received a young, wild group of A. agassizzi about a year ago, they supposedly came from Brazil. Reading about all the different locations that agassizzi are found in, I'm just wondering if the location they were collected from can be narrowed down a bit. They are a yellow form, I think? From what I've read, the yellow form are found near Santarem and also another form in the Rio Tefe drainage. Any thoughts, I'm just curious, they actually were labeled a totally different species when I got them. The pictures were taking over the course of maybe 6 months. Interesting observation I've made, this is the first Apistogramma that I've spawned in which the male has played a role in guarding the fry, the few others that I've spawned, the female has always taken control of raising fry, keeping the male at a distance. Thanks for your help.

Your fish looks like one of the A. sp. aff. agassizii (Netz) forms to me. From which location, I can't tell for sure since all these forms are highly polychromatic. See also this thread.

Thank you for the information, so if I pass any of the offspring around, should I label them A. sp. aff. agassizii Netz or just keep it A. agassizii. I just read in Romer's book, Cichlid Atlas 1, that all the wild color forms of agassizii can show up in offspring from other locations, not sure if that observation has been proven true over time, it's an older book, but if that's true, wow, things are really confusing now!

The A. sp. aff. agassizii (Netz) forms are different species than A. agassizii, not just color forms or populations of the latter. How they are distinguished from A. agassizii is explained here. All agassizii-complex species are highly polychromatic, meaning that different types of coloration can occur in the same population/batch of offspring. This makes it impossible in most cases to tell the catch location/population from the looks of the fishes.
