I dont think ive seen an albino or color morph annectens yet. That doesn’t mean there not out there tho. Albino P. Dolloli are available every so often. Over the years the majority of albino and color morphs like ur example are protopterus aethiopicus. Also, from what im seeing available there becoming more like urs and less “albino”/white… the patches of pigment have nothing to do with a certain species. Albinism is close to melanism…the patches of pigment are black not colored. An albino that exhibits black pigment can be classified as “lutino”… its still an albino tho, hence the red eyes like ur specimen.
Regardless of that, id wager the growth rate also from 6” to 18” in 1 years time sways towards aethiopicus. You’ll know for sure when/if it surpasses the 30-36” mark in a few years time. I too kept a WAL for 10 yrs to around the 30”+ mark. Its still that size. My aethiopicus is 40”+ at 6 yrs old. I too have debated it being a WAL but the growth rate says otherwise. Its hard to tell with them being albino/color morph and they do look pretty similiar to some WAL’s when it comes to head shape/proportions. Mine also has a bit of black pigment. Not nearly as much as urs but as i noted before. The more i see these days… the more black pigment they have.
