Part of why I love putting a lot of different Endlers outside for summer. Some tubs are dark, some are green, varying shade and light. With the polymorphic breeding habits being effected by such things you can get a lot of green irridescence, dark body fish etc.... that you normally can't get in an aquarium. Having to out dance a blue Endler in a green tub is a lot easier when you're a basic black bar or wild guppy carrying a green irridescence patch. First generation you get more like dad, maybe some with larger green patches. But maybe gen 2 meets up with a female also carrying green irridescence. Next Gen you might end up producing a couple lime type Endlers if the water color stays the same.
Collection point is important, but more research is showing the short evolution of the fish is post Spanish due to their dredging. The fish are constantly moving through new habitats and had to evolve different mating practices due to the varying environments. Guppies meanwhile remained stable in their environments because they weren't being developed. So collection point becomes seasonally variable as the waters change and different males suddenly become visible for mating.
I just wish guppies and Endlers did all they do in all their colors, but at like 6-10 inches for males and females lol. I'd love to watch the mating dances at that scale.
