I love that this thread was made because I have noticed the same thing over the last few months. While I love making comparisons, I think that we are starting to get way too specific and then by doing that we confuse ourselves. As stated earlier, scientifically there is only polypterus endlicheri endlicheri, and every sp. falls under that category. The sp. is only there to distinguish where it's from, and part of the reason is marketing. If you take 10 of the same sp. you can probably find some similarities, but you can also find some differences. One of the things I've noticed is that most of the differences we see are color and headshape. Color is something I think can for the most part be attributed to the area it's caught in because of camoflauge. Headshape can honestly vary between variants so I don't think that's something that can be held to one variant specifically. Another thing that has really triggered all this talk is the endlicheri sp. Dabola. Once it came along there was originally comparisons between it and the sp. Dabola. And from there we started shortening it and just calling it Dabola which is also interpreted as a wild hybrid (making some things even more confusing). I think the sp. is starting to become too much of factor in how we judge endlicheri rather than just describing where they're from. I think comparing endli to endli is awesome and really interesting, but in the end they are all still endlicheri and while yes they are the same polyptetus endlicheri endlicheri I think it's really cool to have multiple variants just to see differences and similarities in general. So I think what I'm trying to say is recently we've been trying to do things like determine a variant by factors that vary even between the variants.
