I think not too many people realize that Congo Congicus can also show head markings too (one feature people point out on Lake Tanganyika). Congo ones are definitely more sensitive to substrate/background when it comes to coloring up while the Lake Tanganyika generally will color up very easily on any substrate (that’s their pro).
Also it also comes down to personal preference whether or not you care about little details like the facial/head markings.
Congo ones are still my favorite since they seem to have a thicker/better headshape and for me, headshape is the number 1 thing I look at when buying my Polypterus. (Goes back to preference).
anyway I just wanted to show examples of Congo ones with nice head/facial marking since generally we always see washed out Congo congicus all over the internet. Doesn’t do them any justice.
